Battery Care and Maintenance Tips -EricTheCarGuy

[@shiloh4184]

Mad respect for the detail level here. Dude went 5th dimension on a car battery. Wow.

[@larneyhenry2923]

Making use of the kzbin.infoUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type

[@Flashahol]

As an electronics tech I'm very well versed in batteries, but I never thought about checking for voltage differential between post/connector and post/body of the battery. This is by far the best and most complete car battery maintenance video I've seen.

[@mrtron1850]

I don't understand why the voltage differential between the post and the body would matter at all. The posts aren't (normally) connected to the body.

[@rocketrider1405]

ya, aren't you actually creating the path for the current/voltage when you use your leads?

[@Flashahol]

A DVM does not create a path for current when measuring volts; this setting has an extremely high internal resistance. If you are measuring for current, this setting has the lowest internal resistance and, therefore, you are creating a SHORT (the only setting the DVM fuse(s) are there for)! A DVM should be understood properly before handling, starting with Ohm's law.

[@Flashahol]

The negative post is used as a "ground" or, more correctly said, a current return. If your engine block is not "grounded" properly to the negative battery post, you will never get a spark from the plugs as the current will have nowhere to go to.

[@benzeneau1]

I do like your approach to the safety aspect. However, since i have been involved with big Battery Backup systems, sometimes those involve a lot of Batteries connected, with enormous short-circuit Amperages, i feel, it might be prudent to use tools, that are insulated as much as possible. Your spanners and socket wrenches might slip, and then, even a 200Ah Car Battery might turn you into a pizza face. Safety glasses or not

[@mrbiggoggles314]

Eric, you have saved all our asses 1000 times. Everyone appreciates what you're doing man.

[@davidweum]

I'm a big fan.

[@PhattyMo]

Good video. Keeping batteries clean can help prolong their life. I usually start with spraying the battery with a hose. Another tip for topping off the cells,is to use a big veterinary syringe. Keep baking soda on hand -if you spill acid,or get it on your skin,put some baking soda on there,it will neutralize the acid. (On skin,it helps to make the baking soda into a paste,with a bit of water. Apply it to your skin,wait a few seconds,and then rinse with plenty of water.) If you get acid on your clothes,consider them a goner. There will be a hole where the acid was,after they are washed.

[@allinsiteUK]

May be worth considering an insulated cover for the positive terminal connector. As you say, in an accident a short with the body/hood could cause a spark and ignite escaping fuel. Vasaline for the posts too to prevent oxidation etc. Great video, thanks Eric.

[@nathanrice1796]

One of the better 12V car battery videos I've seen. Showed a few techniques I'd never thought of before.

[@spresc2180]

When there is surface drain, there is a trace of sulfuric acid on top of the battery case providing a current pathway between the terminals. Dust/dirt by itself is non conductive unless wet. As abhorrent as it may seem to some, I verify the presence of sulfuric acid (unless I can actually see it) by lightly touching the case top and then taste test. Then spit it out. My tongue has not been burned nor fallen off from occassionaly doing this for well over 45 years. Yes, I know baking soda will tell you, but its not always nearby. Excellent battery care video.

[@trucavalier]

25 years of fooling around with cars I’ve never even thought to check the case for draw. Thanks a million!

[@harindugamlath]

Surface drain. Never thought of that! Thanks Eric!

[@dominicfong6341]

I have never heard of that either, Eric is good isn't he!

[@javaman2883]

@Rex Erection "I passed on college because it's for simple minded people that think they need a piece of paper to be successful in life." College is not always optional. My father-in-law had been working for a company for 22 years, moved up from the bottom. For several years he was even teaching the newcomers to the company how to do CAD properly because the universities were not preparing them well enough. The company owner wanted to retire and sold the company. The new owners let my father-in-law go because he did not have a university degree, which was now required. He tried applying at many other CAD companies, none would hire him because he lacked the degree. So he went back to college, got his four-year degree, and got back in the industry.

[@JohnDoe-le8fy]

Eh .. I don't think that actually does anything, he's just measuring the potential difference between those two area's. It's "conductive" dust.. not draining dust or that battery would be dead all the time.

[@DENicholsAutoBravado]

Great video Eric. It was a mix of why I became a subscriber in the first place and the quality of production your capable of with all your skills and experience. My inner motivation for watching these things over a year and a half ago slowly went from loving cars to wanting to be an Automotive Technician. I've been hired! Thanks to everyone's comments as well that has prepped me for this moment! :)

[@pay9011]

I was listening to an old time radio program than included the sponsors commercials. One was an auto battery manufacturer. They were proudly touting that their batteries only needed water added 3 or 4 times a year (under typical driving).

[@JeffHazardous]

Just a quick tip for a few people who have batteries in their trunks, like my 05 Cobalt, it is very important to reconnect the venting tube if your battery is equipped with one.

[@StoneKathryn]

Thank you Eric the Car Guy! That is what my no start/no crank issue was! The negative terminal connection was loose and was not adjustable so $10 later with a new cable the car started right up. I thought it was something else since my headlights were bright but my car wouldn't crank and then not even the dash lights would come on. Put the new cable on, voila, it is a car again! Thanks so much for pointing this out. My other car ('94 Pontiac Grand Prix) that did this too, it was the bolt that threaded into the positive side of the battery that had somehow gotten stripped and I did get a new battery and a new starter before I figured out it was the bolt. I'm so glad I didn't do that all over again. Thanks again!

[@shorelined1]

Love these videos. I'm amazed how much of a drain a little dirt created! Good to know in dusty Az. I used to test for good connection/hidden oxidation similarly. After getting solid read at posts, switch one probe to opposite clamp/terminal, also on wiring, looking for any fluctuation, then compare to initial voltage read. Repeat for other side. I used to use wire brushes until a few post and clamp got too worn to connect tightly. I started using a few drops of lime away for toilets(buck at $1 store). Just a quick scrub with sponge or toothbrush, wipe dry and it's nice and shiny. I put a thin film of white silicone grease on exposed metal to displace air and prevent oxidation.

[@ericrowland1851]

I've watched a few videos about battery care, but this is undoubtedly the most informative I've seen. I was beginning to give up on finding a decent instructional, but this has now changed that. Very grateful for this. Splendid job!

[@spiralnapkin]

Videos like like always motivate me to get up and check things out for myself. I checked my voltage, and it was 12.12v. I checked for surface drain and got over 10v in some places. I cleaned it up with water and baking soda until i got 0 everywhere else. And when i checked voltage at the posts, 12.33v 👍. I know its not the 12.4 we want, but I feel a lot better than it being 12.12v. Thanks Eric!

[@skhumbuzocele1330]

First 3 minutes....It is clear that I am speaking with a proffessional....just getting helped....you are burning fire Eric🔥🔥🔥🔥

[@scottsullivan7716]

Old vid, I know BUUUUTTT dielectric grease AKA silicone paste is used instead of 'axle grease' on the cleaned and installed connectors/posts. It does NOT restrict the flow of electricity and keep em weather free! Love you Eric (platonically of course)!!

[@Caelin100]

Thank you for emphasizing Safety and low cost solutions. Your instructions were accurate, easy to follow and solved my issue.

[@conscience-commenter]

One most important tip for battery health is knowing the date code for when it was manufactured. Always check a batteries date code before purchase to make sure it isn't old. All the cleaning , voltage checking and charging are ok, but knowing it's age and setting a replacement date (5-6) yrs depending on brand ,type and usage are paramount. Especially if you live in a cold climate. I always put an easy viewable date code and record service dates. During service when the hood is up, no guessing is required .Knowing dates for repairs makes it easy for replacing parts.

[@singuranjoferjohne.3341]

❤

[@shiloh4184]

Erics so mello yellow. But hes saving us tons of $$. If he earned half of what hes saved us all on car maintenance, hed be a billionaire. Just imagine ETCG hobnobbing with Bezos and Buffet at the Stay Dirty Country Club and mixed use development site. Seriously man, thank you. I know the editing process has to suck royally, but the final product is so appreciated by millions!!!

[@blkferrari355]

Great video. Comprehensive, thorough and to the point. Eric, your channel is at the top of my list! Keep up the good work.

[@csabcsaa]

thanks a lot Eric! You just saved my battery :) had the same "dirt conducts electricity" issue, and the freshly charged battery, could not start my diesel truck the next day. After I watched Your video, I measured it, and had 6-8 volts charge leak via the dirt (and actually it wasnt that dirty, but still). Cleaned it, measured it and now it has 0.0 volt leak. Charging at the moment. hope it starts now! Cheers from hungary!

[@martinnightingale6033]

Great video . One thing I spotted , it's great to see a mechanic using an adjustable Spanner . I have an 06 VW Touareg 3.0 V6 tdi . Biggest bugbear is if I don't drive it . It struggles to start . Trouble is electrically it's a complex system . As soon as you unlock it and open the drivers door , you can hear something in the vehicle firing up. It took me a while to work out that it's the Webasto engine diesel preheat system . Went out to it today Tuesday , last started Friday last week . First try starting . Probably cranked over for 5 or 6 seconds then stopped . 2 goes with engine preheat (heater plugs ) it turned over normally and fired up sweet as usual . The battery is 8 weeks old from new . I know only too well it's got a parasitic drain .

[@samjohnson466]

Thanks Eric. I had no idea that the battery case could become conductive, something else to check on my vehicles, good one.

[@davidbirch9969]

Don't forget to clean your ground connections! They're just as important as your battery connections.

[@dixoncider7256]

David Birch and sometimes i find unfortunately more important.

[@rahmatalicarexperttrainner5229]

Also you can clean it by hot water and use vaseline on battery terminals.

[@antypanag1]

sir ! u did the BEST video for battery maintenance i have seen in youtube . completed and well explained. seems to me u got it. i bet u r a far more good than an average car technitian (sems to me u like ur job) !!! thanks a lot for ur efford to deliver us this knowlege !!!!! greeding from greece !!!!

[@johncspine2787]

Just got a CTEK charger/maintainer, it’s interesting to see how my battery, although in great health, wasn’t fully charged as I am disabled and don’t drive much. Glad you showed surface drain..too many ppl let their stuff get really dirty, this can really drain the battery!

[@scd6969]

Knowledge is priceless. Thanks EricTheCarGuy for sharing your experience and knowledge for free.

[@jeremylakenes6859]

The dielectric grease is good, not bad, because if it gets between parts it insulated from arcing. If the parts are clean and make contact (dielectric grease will not prevent contact connections...) the grease will move out of the way and will allow contact. Also, likely the terminals are not steel and they won’t create sparks... Other than these things, good video.

[@draytonPW]

Having red cables going to both positive and negative would drive me crazy.

[@vasuv59]

Yes that is confusing

[@draytonPW]

@zdringy your dumb.

[@Raj-nh3fc]

I noticed that too and thought that Eric was about to connect wrong way around untill I realised that both leads were red. Bad to have same colour leads.

[@alexoneal1029]

Thanks Eric...great to learn that surface grime can put a voltage drain on a battery....

[@Grainsauce]

That is amazing, I've near heard or thought of surface drain being on the battery body itself!!!!

[@ACCESSeVENTURE]

Excellent, I will be showing this video to my high school class, Life Skills. Thank you Eric

[@TOURMANBOB]

I knew most of this other than the voltage leaking across the top. However, it is an excellent video clearly explained with nothing flowery about it. Also attention paid to the hold downs and the pan the battery sits on is worth doing. Thank you

[@johnlong384]

Thanks for the cleaning tips on the battery housing which I was not aware of to cause problems.

[@PistonShack]

One of the best video how to charge the battery properly.

[@gweedomurray9923]

You forgot to tape over "Chicago Electric" on the resistance pile meter. :-D

[@johnkinnane547]

Good vid Eric. Batteries always seemed to be over looked to other Non starting issues. Thanks for mentioning not to smoke around them either. I have seen a battery slip straight into the fan this was years ago when fan blades were metal because somebody was too lazy to tie it down, what a acid mess! Thanks mate Johnno

[@gglovato]

Eirc, instead of axle grease, use solid vaseline in the terminals, it will prevent corrosion via oxidation and sulfacid completely and won't affect the connection. You can also use a special gel that's used for electricla connections(usually comes in telecom boxes to keep moisture out) but it's sticky as hell and very expensive, vaseline is much better We use that on stationary big UPS batteries and haven't experienced any problems, wherever it goes away the terminal corrode

[@Cryous]

That stuff you're talking about is flux

[@gglovato]

Cryous no, i meant electrical gel sealant like www.arrowelectricals.co.uk/electrical-accessories-c33/electrical-sealants-gels-c42 or www.xmultiple.com/xwebsite-sealant-GEL.htm

[@alanack67]

OR used sealed batteries like optimas. I was tired of stuff rusting under the hood near batteries

[@johnfranks]

I like NO-OX-ID A-Special. 8oz tube will last a lifetime.

[@johnfranks]

Alan Ackaway Sealed is the way to go if you can afford the difference. My last battery was a Odyssey and withstood 8 years of abuse. No maintenance, no corrosion! I'm giving Optima another chance this go round since they were about $75 cheaper.

[@camomanofcranham]

Great video Eric....just ordered a load tester and a battery post cleaner... bin working on my own cars for over 45 years and never come across those little brushes...cool little mother's...

[@Youngsoldier93]

Eric, you're the man! I never knew that the dirt that sits on top of the battery can actually drain the charge! Good thing I always try to keep everything nice and clean, lol. Keep up the good work ETCG!

[@lonniebanark4917]

[@mondeo984]

BOTH cables in red color ? Hehe, not the best choise to avoid mixing up plus and minus when reconnection cables again.

[@moparone22]

I remember when BMW used black for positive and brown for negative.

[@FGuilt]

I was thinking the same thing...

[@oshinaslanian3221]

moparone22 Really!? When was this, on some of the earlier models?

[@MrGencyExit64]

One's pink, apparently ;)

[@billybobjoe198]

moparone22 Black in your residential wiring is the hot wire. With white / bare being a neutral/ground When a dedicated ground is insulated it's usually insulated in green. Red in residential wiring is usually used as a secondary hot wire in romex. For instance in most circuits in your house you will find 14/2 (14 gauge, 2 insulted + ground) Black (Hot), White (Neurtral), Bare Copper (Ground) Some you will find as 14/3 (14 gauge, 3 insulted + ground) Black (Hot), Red (Hot), White (Neutral), Bare Copper (Ground). Black as a positive terminal isn't that odd. Black seems to get over used, because inside electronics and connections it's often used as a ground.

[@danielmckenzie6858]

the last 2 batteries i have purchased were used from late fresh model wrecks, and been very lucky, the cost of a new battery eing around 130 is insane. I Saturday had to get another battery for my 95 Corvette, it had a bad cell, went to a junk yard and got a used one for $30 dollars, whats your take Eric, your videos about this save me from having a bad moment from happening

[@room101935]

Hi Eric I use a sugar soap solution in a spray bottle which seems to work well at dissolving the grease on battery boxes, when you look inside the cell it's important to check the colour of the water inside and the colour of the cap, as battery's age the get a build up of black gunge this can be a sign of a battery on its way out. Its important to note on battery's 580ah and above the load tester you used will not load the battery enough as it is an element tester and only good for 100 amps or so a larger carbon pile tester is required that's good for 500 amps.I also check neg/ground back to the engine. Vasaline is a good terminal protector.

[@ranger178]

i like to put a miniscule amount of copper conductive grease on the posts .it is made for electrical panels for painting into wires when clamping them in a panel. then i clean up any excess so it does not make a short on battery top and paint some silicone grease to seal terminals. they may get a bit of dust on the grease but the terminals are never corroded four years later when i change battery they are as good as when i installed them.

[@cecewd405]

Thanks for the close up of the battery water levels👍🏽

[@markbenoit]

Hey good stuff. Some thoughts I wanted to add: • The positive post should have some kind of cover. If The battery comes loose and makes contact with the hood or any piece of metal or you set tools on top, it could spark. • you should clean under the battery is well a lot of corrosion happens underneath the battery. A lot of people don't have a battery holddown because the corrosion is so bad underneath their battery that the mounting point/bracket is damaged. • I haven't found that those green and red sponge things do anything as well I would say skip it.

[@compactc9]

I make a point of regularly washing out the engine bay on my truck, and when I do, I always make sure to clean the top of the battery thoroughly for this reason. I started doing this because I thought all that stuff looked nasty, but then Dad told me I'm actually solving the conductive filth issue as well.

[@marksthoughts4721]

Good "old school" tips. Great job. I have used most but forgot a lot. Also learned new ones. Thanks Eric keeping running in a cold morning or night.

[@Mak933]

Eric - These videos are as good as gold. Keep up the good work!

[@84chevyguy]

Had no clue this could happen... Thanks for this video.. This explains alot of dead batteries ive had.. Great job eric.

[@harrybrooks9634]

WOW! Thanks for free education! I needed to know/learn many things you taught! BUT you forgot to teach us how to get the gunk out of the tops of each battery cell! Would that suction bulb thing you showed us do that??? Actually I was seeking a more basic just checking liquids levels and filling with distilled water...for my wife working in LA. Do garages offer this service? I have NEVER seen or heard any advertisements. Why don't battery sales outlets provide this service especially in the Fall? Would seem to be a great savior preventing dead batteries! As a chemist I liked your showing folks and warning them about the "strength" of the sulfuric acid! Have you done windshield wipers??? NEXT? PLZ!

[@michaelchitwood6226]

Great educational on how to use a DVOM.

[@dandeleona4760]

Interesting about dirt conducting current. I wondered if that made a difference. I also didn't know slow charging is better than fast so that info was useful. I think those pads were designed to stop charge leaking to the surface of the battery by lifting the wires off the case with an insulator felt. Of course if they get dirty and conductive, so much for that function.

[@cac7549]

Eric, this is an excellent video with all the information. You are our man. Great.

[@battosaijenkins946]

+Carlos Elias Remember to be in a well ventilated area for the baking soda. It reacts with the leaked green stuff and I almost passed out from the fumes... VERY TOXIC =(

[@cac7549]

makes sense yes.

[@99unlv11]

Thanks Eric. Very informative video. I enjoy watching all your videos.

[@tasmedic]

If you're checking for voltage drop between battery post and the terminal, switching the headlights on first will make the voltage drop much easier to detect.

[@jeffpv.]

Very well done video! I had a car once that someone used a red wire for the ground. I simply wrapped the wire with black electrical tape to better identify the wire. Someone could connect jumper cables backwards and have a real problem.

[@shannonsisk]

really great video Eric. I would guess that most people just think of these batteries as they would batteries in a remote control. Non serviceable, no maintenance needed, just replace as necessary. Battery maintenance goes a long way and helps to save you money!

[@Aluzcz]

Quick question: Can a large fast battery charger be hooked up to the house batteries of a driving RV

[@namjignerak]

excellent point on battery surface drain; I had similar problem before.

[@JustMe-cf6kr]

Eric, Once again, a Fantastic Job. Your videos help me teach my students automotive. I like that you not only mention safety glasses, and the safety aspects. You do them. You show it how I want them to do it. Video first, hands on second. Great Job.

[@givoneam6657]

Thanks Eric great video ...appreciated the time and the effort...we need more video like that

[@algernonfriday4824]

Beautiful, was not expecting the residue as a conductor insight. Yes, Coca-Cola, Pepsi, and any carbonated drink in general can be used, or is used. At least with these nuances: 1) in a hurry, 2) for the scaling up in the posts is perfect, 3) for whole battery is news to me and would still likely require a real cleaning as the congealed syrup would attract insects at least in Puerto Rico, or in the summer in the mainland.

[@SilentGamer-jt8dl]

Hey Eric, excellent video as always. But I'm struggling to understand why you find it necessary to cover up all the manufactures names/logos throughout the video?.

[@spudmunson3976]

It is not about copyrights. It is about giving manufacturers free advertisement. They know what Eric does in his videos if they want product placement they should have to pay for it. Why give corporate America a free pass. None of us ever get a free pass from these corporations.

[@ajbrown7245]

So I guess ZEP paid for some advertising then? I could care less. Eric's video's are so informative.

[@henrikaleksandernilsen6388]

It's just a product, and everyone uses products. I don't care about which brand the baking soda, battery or battery charger are from, and I don't think anyone else would either. Also, Eric has a lot of viewers all over the world (not just the US) who wouldn't be able to buy these products anyway.

[@BigDaddysGarage]

AJ Brown I think ZEP sent Eric a goody bag (or goody box). So yeah that kinda answers the question too....Wanna see your name on a EricTheCarGuy video? Send a box of goodies!

[@TheWizzyWizard]

AJ Brown I think you meant to say "couldn't care less"...

[@VintageCars999]

Never thought to clean off the surface but these are some good tips for a long lasting battery.

[@robertmattison1282]

Use a PLUMBER Brush to scratch the terminal clean. Excellent Video.

[@aserta]

Baking soda is good, but another thing i use and that's perfectly safe on plastics (because it's designed to use on such things after all) is clothing detergent. The powder kind. Scoop some on an stout brush and scrub.

[@jcharles1470]

This is the best video about battery maintenance that I see!!!! thanks a lot!!!

[@Dhi-fe5eu]

Great video. Could you make a video showing if your car will not start or turn over. How you can tell if it’s the starter, alternator or the battery using the voltmeter.

[@mohandasu43]

Mr. Eric, a good and a wonderful information to take care of the batteries for all around the world. Than you sir.

[@marcsultana3311]

Nicely done, Eric! I like the emphasis on safety. I'm a subscriber. Keep up the good work. Thanks.

[@simonthebroken9691]

Thanks Eric. Great review. Sometimes I forget a detail or two.

[@austinallen7691]

I love your videos man. Very descriptive and honest yet straight to the point.

[@waynerlee]

In NYC, I just use tap water with a stiff brush. Our tap comes from surface water as oppose to many municipalities that get their water from the ground that may contain far more minerals. That would be more conductive than NYC water, which has hardly any conductivity.

[@SomeGuyInSandy]

That's a great tip Eric. I didn't know about the "surface drain" thing at all! I'll be cleaning all of my batteries this weekend, thanks! (seriously, I will, lol)

[@AsTheWheelsTurn]

awesome, good info and well presented. thanks! I had a battery I thought was bad and was going to replace but I found it was a combination between dirty connections,little bit of a surface drain and a little bit low on water here in 116 degree phoenix heat. It seems to be working like a champ now.Thanks for saving me $120.00 battery is only a year and a half old so I wasn't quite ready to call it quits on the thing unless I had to.

[@TechTimeWithEric]

Just a suggestion: I can tell you from working at Advance Auto that if you pop the caps on one of their batteries, your warranty is void. That is an Auto Zone battery, and I know their warranty is similar. Just because the caps are there, doesn't mean that you should take them off, that's why they're labeled as maintenance free. Otherwise, this was just like watching the training information from Advance Auto.

[@michaelthomas4156]

Great information/video. Thanks for stressing safety (safety glasses/gloves).

[@LA_Commander]

Great video Eric! Although I a red negative battery cable doesn't look too cool man, since you changed out the terminal might as well put a nice new cable on there too.

[@derekrowlands1189]

Great video thank you very much, could I use silicone grease on the terminals instead of axle grease?

[@rockslide4802]

Try brushing some Vaseline on your battery terminals and cable connections. I use Vaseline (petroleum jelly) and an old toothbrush, both of which I keep in my tool box. Works great. An old mechanic taught me that in the late 60s. Still works like charm. I never have corrosion on the terminals.

[@boblee5438]

I have an Odyssey battery. No maintenance required. Awesome battery!

[@JamesMossR33]

Regardless of whether or not damage may be caused by reversing the cables briefly, having a red earth lead just gets my OCD twitching. I would have had to take 1/2" off the earth cable to get back to some pristine copper strands when swapping the clamp. But that's just me and I thought this video was great Eric.

[@andynghiem1014]

Fantastic! Both positive and negative cables are red.

[@DrWenChannel]

Hi Eric, really like your channel. Just a quick question. My wife only drive her car locally (almost no highway driving). Would the alternator get enough chance to charge the battery? Someone told me that normally alternator only start charging batteries IF the car is driving on the highway (e.g. >50 MPH), is that true? If the car is mostly driven locally, would it be a good idea to use a car battery charger or maintainer (e.g. Schumacher SC1319 1.5A 6V/12V I2Fully Automatic Battery Maintainer) regularly to keep the car battery full charged (like maybe once a month)? Would that prolong the life of the battery? Thanks!

[@sonyyoung1036]

Your videos are the best I have seen to educate DIYers like me. I understand your rule of thumb (9.6 volts or higher) when doing the load test and noticed you did not use CCA scale on the tester to see if the pointer is in the good or bad zone based on your battery CCA. Any reason for not using the CCA scale reading? Thanks

[@lahmyaj]

15:15 - What about submerging the battery terminals themselves in a bi-carb soda/water solution? Or something else to clean them up?

[@McmM-cv9sb]

That was real good Eric a pick up a few tips that I didn't know about and Battery care thanks again love all of your videos keep up the good work👍

[@Commodore-dr6oj]

Was quite surprised with the surface drain great video Eric

[@paulk6216]

How to remove stuck battery terminal clamps: Use a flat end screwdriver or the pointy end of a file. Stick it in the gap where the two parts of the clamp come together. Gently tap with a hammer. Clamp should open up and be easy to remove.

[@jameskoralewski1006]

Also, check the tightness of the ground wire from the negative battery terminal to the body ground.

[@MCFIXIT]

This is fantastic! Thanks for all your insights over the years!
