How to Test a Car Battery with a Multimeter

[@razoromero]

Dude, thought you might like to know that eight years after you made this video, it's still helping people. Thanks man, I found it really useful this evening.

[@jillianlyons6092]

Agreed!!!

[@CaneCorso888]

As a woman I so appreciate this video! I had a mechanic tell me the battery he sold me was fine even tho I’ve been having issues with the car starting for a week and a brand new alternator. He tested the battery with a charging unit on it and tried to explain to me that’s how it’s done. 🤔 this video confirms my suspicions were right and he is shady af! You have a new subscriber! Happy I’ll be more educated about my car now! Thank you!!!!

[@elementalraven27]

I’m a 44 year old women and I’m trying to learn how to do as much of my own vehicle maintenance as possible but didn’t want to ask for help with the volt meter- Thank you for helping me swallow my pride a little :) Now to check the alternator video out!

[@chrisfix]

I'm glad the video was able to help you with the multimeter!

[@elementalraven27]

Until I started actually shopping for them, oh my - the choices and variations! I decided I wanted the thermocouple and no touch sensor - couldn’t make up my mind so I purchased one made by Ames instruments from harbor freight for about $44 and then I found a similar device at Walmart made by ever start maxx that cost just under $30… is one of those any better than the other, if you’re going by brand?

[@elementalraven27]

Personally, I like the ever start because it’s a slightly thinner profile whereas the Eames is a little chunky, but I plan on returning one of them and I just want to choose the right one..

[@Alexio.-]

​@@elementalraven27 If your goal is just to measure battery voltage, brand shouldn't matter that much, I have some unbranded chinese multimeter, that is a few years old, I compared it to the professional "fluke" brand we have at work, the measurement is the same.

There’s been a multimeter laying around my house and I never knew how to use it 😅. You’re great Thanks 🥳

[@psdaengr911]

Even the free Harbor Freight meter comes with a basic instruction sheet, often printed in more than one language. If you couldn't take 5 minutes to read it, I'm guessing that you probably never read the hundreds of pages of your car's owner's manual, and don't truly know how to use all of its capabilities properly. (Most people don't RTFM. )

[@ulicornprocreateartclub2617]

Dude thank you so much. I got my car back from the dealership where they were supposed to do a full inspection and had battery problems the next day. The positive lead was totally corroded! You gave me the knowledge to not only fix the issue but also raise hell with them.

[@chrisfix]

I'm glad the video was helpful!

[@jnoll661]

Just bought the same multimeter and searched how to test battery, I know nothing on how to. Came across this video and what a FATASTIC visual and verbal showing of how to use it. MAJOR KUDOS TO YOU saved me from electrocution and the headache of dealing with a 2 year old battery that was dead 2 different times when starting my car. Many thanks Chris and needless to say I subscribed to your channel 😀

[@CarsSimplified]

To anyone with a multimeter with a min/max setting: When testing to see how low the voltage gets when you start the engine, set your multimeter display option to "min" (minimum) and it will keep the lowest voltage it reads on the display for you. Super handy, especially if you are performing the test by yourself!

[@pay9011]

Great tip.

[@nyczumazooma]

Um hmmm

[@EatSleepShift]

My . min is 9.5 or something. Is that bad?

[@LouisOtto]

@@EatSleepShift Not bad, no, but heading that way. Keep checking it semi-regularly and if it falls to 8 or something then start to think about changing it if you haven't already

[@MuckingMunt]

Mine hit 8v very briefly whilst starting just now. It's been a bit sluggish to turn over the last week or two, and flattened after about 36 hours of no use yesterday. Mains charge over night and tested this mornign per this video. Charge outta the alternator seems good and consistent in the low 14.0-->14.4v range, even with/without accessories and lights going. Considering the battery is 7 or 8 years old.. I think I might give it a dignified retirement and replace it. It's had a good run, so I think I'll stick with the same brand too.

[@y2kroxy]

One thing to note, the green residue seen on corroded terminals is sign that the corrosion is eating up the copper. You will see pitting in that area after you have cleaned the connectors. This occurs occurs when you have tin or lead plated copper connectors and do not use any rust inhibitors. A special conductive grease used extensive for station batteries is a product call "NO OXIDE A". A thin film is used on the post and in the inside and outside of the connector. Please note in your video you suggested using sand paper and the terminal shown at 3:40 show that the lead coating of the connector was exposed which can introduce corrosion problems later on. Most battery terminal connectors are tin or lead coated for this reason.

[@bixby9797]

10 yr later I came across this and got the multimeter out for a F150 battery. Went down to 9.7 volts so I took it up and swapped before winter just in case. Still helping people! Thanks

LOVED IT. You have the same multimeter I use (I have no idea how to use it, but it’s the same one in the picture). Found a 3-year old battery that was sitting on a hidden shelf and it’s working perfectly!! Clear, concise, and straight to the point info, it saved me close to $300 !!!! 😊

[@chrisfix]

Awesome! Thanks a lot! Might be worth getting the battery tested just to make sure its still in good shape

[@andrewn2011]

We took it to Sams Club and they said it was a little low and probably need replacement. Its got a 7/12 sticker on it so I assume thats just under 4 years old. I just received my new multimeter and did this battery test just like you said. It registered 12.46 after the 2min lights on and when we started up it drop to 11.65. I guess I'm going to keep my battery and add it to our monthly maintenance check, but your video just saved me from buying $100+ battery I didn't need to get just yet. Thanks a lot for your time and efforts. Keep posting those videos for newbies like me.

[@dmack177]

Andrew Nakamura They were probably talking about your cold cranking amps

[@paulgeneslapining1655]

Yes, 11.65 is a little low

[@tannerfrancisco8759]

​@@paulgeneslapining1655dropping to that when cranking isn't bad at all though. My drops to 9.78 V when cranking on a cold day and it's no biggie. Most any place trying to sell you a battery is going to say that's bad and while it is starting to go, that's not bad especially if you get 2.5 more years out of that battery they said was bad. If you are in extreme cold or extreme heat that battery is going to go a lot more quickly than that though.

[@Erki36]

I never thought that I will remember that Chris uploaded a video 8y ago that I will need today

[@bobross9648]

Love your vids Chris .... a couple of things though: To clean battery posts you should remove the terminal and clean the terminal inside and the post outside with a battery post cleaner tool - just spraying the outside with WD-40 doesn't get into the electrical contact area of the connection. A little Vaseline on the connection after assembly will keep corrosion down. When adding water to a battery you should use distilled water, not bottled water. Bottled water has dissolved minerals & salts but distilled water doesn't.

[@hartzellaerialproductions527]

Much appreciation brother! I try to work on my car as much as possible and wanted to try to diagnose the issue on my own. My battery is dropping to 7-8 and I’m sure that’s why it’s struggling to start in the PA winter. 10 degrees this morning. You helped me save a lot of money!

[@eduardopina5233]

Nice job, clear and concise without a lot of unnecessary fluff. One other comment, I was always told to use distilled water, bottled water or spring water or mineral water may hurt the life of the battery by causing corrosion. I’m not an expert on at $.80 a gallon I would buy distilled. Thank you.

[@greencupbay]

Thanks so so so much man. It’s 8:30 and I have jobs and contracts lined up but my pressure washer stopped working and cranking. Just checked and it drops to 0v when trying to start. That explains why I needed an external battery pack sometimes and why it’s not running. You just saved me a ton of time. I’m off to pick up a new battery in the morning.

[@chrisfix]

I'm glad the video was helpful!

[@bradster1708]

Great video, just like to add a couple of things; 12V is the nominal voltage of a 12V battery, the actual normal voltage is 12.6V. When fully charged it should be in the range of 12.6 - 13.2V for a very good condition battery. If your battery is under 12V when fully charged it may be on the way out. I am a little sceptical of maintenance free batteries. They seem like a normal battery with easy access to checking electrolyte levels blocked off. When my Mazda 3 battery seemed bad, only 3 years old, I removed the panel covering these and found that the levels were very low. I topped up with distilled water and used a smart charger to resuscitate it. The battery lasted another 4 years, just gave it some TLC every 6 months or so.

[@Boz1211111]

Fully charged lead acid is between 12.7 and 12.8. it cannot be more than that. Also. Voltage is measured after proper rest time of 12-24 hours. If you measure it right after charging thats the reason it shows more but that voltage cannot be used to determine state of charge or battery percentage

[@paulmaxwell8851]

Yeah, I have mixed feelings about 'maintenance-free' batteries. I do use them, and they do tend to stay nice and clean, without the corroded terminals you get with flooded batteries.

[@LongTimeTTFan]

[@aleblanc3547]

Another good one. I've used a baking soda and water mixture (1/4 cup baking soda to 16 ounces water) to neutralize the acid on top of the battery and around the terminals. It does a great job of killing that corrosion, but the mechanical action of the sandpaper is still needed to remove all the residue. That WD-40 suggestion is a great idea. Thanks, Chris.

[@chrisfix]

Great Tip! Thanks a lot! Glad you found the video informative!

[@Quentyn73]

I was about to say the same. You don't need a solution, just sprinkle a teaspoon of baking sodium on the positive terminal, spray some water and let chemistry do its thing. Rinse. Don't let acid crystals get on your clothes or this will be the last time you're wearing them. Obviously rinse well from any metal parts our comes in contact with. Use only conductive grease or none at best.

[@edr121]

WOW! Thank you so much for your insight. I have been troubleshooting my 2005 Chrysler T&C Touring 3.8 for a month now and nothing seemed to work. The symptoms were as you described erratic dash panel, headlights inconsistently browing-out, vehicle turning of while at low revolutions, multiple error codes including cylinder misfire P003. I changed the alternator, cleaned battery terminals several times, checked each relay in the PCM box, took out dash panel an re-solder it, check al fuses, and the list goes on... and on. Until I came up to your idea of checking the battery and changing the battery terminals for Marine type. Wow! my battery was going bad, but my terminals were bad too. No more problems. Thank you!

[@wholeNwon]

Common voltage-related gremlins.

[@OidHunter]

Good video. I would use a spark plug brush and electrical cleaning spray to clean the terminals instead of sandpaper, then apply a thin layer of battery terminal grease to prevent the galvanic corrosion. You can also buy a battery terminal post cleaning tool, this has steel bristles plug to clean the connectors, and a bristles hole to place over the battery terminals, this works well. Wd40 dries out and is a water displacement spray (hence the "WD") not a lubricant.

A good load test is the "cold flood crank" mode. Turn key on, floor gas pedal and hold. Turn it over and it should just keep turning over. Not all cars have this so if it starts immediately let off of gas. Generally I'll crank it for 5-6 seconds and see what the batt voltage levels off at. Most ford and GM use the clear flood crank to clear flooding condition. The ECM does this by either cutting fuel injection pulse width or ignition system or both. This is a lot of info but good to keep in memory. Also fun to mess with people lol. Love the vids Chris. Lot of great info!

[@chrisfix]

Brenndon McGill Thank you man and thanks for the tip! That is a great way to test the engine load!

[@averyalexander2303]

Cranking the engine for a few seconds won't damage the starter. That's what it's designed to do. And the comment about damaging the engine by cranking it is completely ridiculous.

[@1LeggedGuy]

[@doctor_fever]

Thumbs up on this video, with one suggestion: Battery terminal corrosion pads (chemically treated green & red felt washers) provide protection without gunking up the top of the battery the way WD-40 (or any non-evaporating spray) does. A light grease layer over the terminals provides an extra layer of protection. Oh - it's nice to see someone else who likes that simple and cheap Cen-Tech multitester! Mine has lasted and lasted.

[@ThePackDad]

Are you recording the multimeter in the engine while starting, then reviewing the video to see the numbers, then resuming recording? Didn't seem like any else was there.

A distinction should be made between bottled water and distilled water. Bottled (drinking) water is NOT distilled water. If you have a "wet" battery with caps, only add distilled water. Regular bottled drinking water does have minerals. I only mention this because you said to use bottled "or" distilled water. Only use distilled water, which is bottled, of course, but drinking water is also bottled.

[@dukeman7595]

I'm sure distilled water would be better, however, I have used plain old tap water for years without any adverse effects.

Chris Fix, thank you for your most excellent wealth of knowledge.

[@benjamingarcia661]

My Rav 4 no power, I check everything, and I was getting ready to tow it to the dealership and pay $$$. Then I watched your video and there it was broken cable😂. Thank you very much. My car running fine. Wish I could post a picture

[@robertmiller1293]

I found that these videos helped me out big time. Thank you

Vaseline/Petroleum Jelly is good to put on the battery terminals to stop them rusting also...

[@chrisfix]

lee major Thanks for sharing the tip!

[@flagmichael]

I like the Permatex purple spray.

[@Rusiputki]

Please do not put any crap on the battery terminals, just wire brush it and it's good for years or until next acid leak. In other words dont waste your time getting dirty every time you move your battery.

[@allsystemsdownagain9553]

Vaseline is good for masterbating also. My post is good and hard.

[@WesleyVantHull]

Nothing beats battery terminal protector..

[@rvnmedic1968]

Excellent video production, clear instructions, well done! Very helpful,Chris.

[@bluebox212]

Hey Chris, is it just me or am I the only one that feels like car stores will MOST of the time recommend a new battery...even if you don't need one? Great tutorial btw....

[@defons1234]

I was told by Walmart service adviserthat my two year old max start battery was good by checking the voltage. I told him to do a load test on the battery sure enough the battery had a internal current draw and they had to give me a new battery under warranty. Thanks to all the good information on KZbin such as from Chris. So make sure ask them to do a load test on your battery when you want it checked.

[@rolandmetayer7210]

I agree! Often the " Bigbox Stores " want to sell you a NEW BATTERY ! PERIODDDD ! ! !

[@2003evodave]

Why are you getting batteries at a “CAR STORE” ? Big hint,,,next time try an auto parts store.

15 years I have owned a multimeter and never used it. That changed today. Many thanks.

[@GrandmaSezSo]

I took my lawnmower battery to a parts store and they put a meter on it and said it was no good. They wanted to sell me another battery. I told them the battery had been sitting for two years so asked if they could try charging it. The guy said, it was a goner. His exact words. I said ok, thanks, and took my battery and went to parts store up the street. They charged it and THEN tested it and said it was fine. Parts store are not always honest especially with older women so I found this video helpful so I can get a meter and test my own batteries.

[@dezhaowu]

I really like these people who make videos and give great suggestions to help people on the internet. Thank you so much!

[@chrisfix]

Thanks!

[@analise17]

Thanks for being succinct and not mansplaining in your video. You get right to the issue, and it's really appreciated!

[@Frontlaven]

Great vid, I got the same free HF multimeter too.

[@chrisfix]

Thanks! Yea, it is a good cheap multimeter!

[@kevinatspeed]

ChrisFix Cheap is correct. Why is it free? Cheap. However no one on this planet wants cheap. What you want is a good value. For example, I intentionally bought a 'cheap' IAC that was advertised as "High Performance IAC". There is no such thing. My response: www.ebay.com/itm/181344884708

[@chrisfix]

Kevin Johnson lol, good point. Cheap and a decent product.

[@paulk5311]

i had one of those. gave it away. it worked ok but the leads broke right at the elbow. i fixed one side and then the other broke and since my brother gave me a good one i just passed this one off to someone else. so now i only have two, a digital and an analog one.

I don't even have a Multimeter (on my way to buy one) this was so clear and helpful! thanks from the Dominican Republic.

[@MrLaChien]

Thank you Chris, I like your videos over the years, you don't waste our time talking crap or selling expensive equipment

[@kellyokamoto1604]

Extra "old timer's tip": Once those terminal posts are clean, lightly coat with petroleum jelly. Been doing this for our assortment of vehicles for over 45 years and have never seen an adverse effect. Keeps the posts from forming corrosion.

[@chrisfix]

Thanks for the tip!

[@bbrad628]

Dielectric grease on terminals to prevent corrosion
