Choosing the Right Battery Maintainer / Charger for your Car or Motorcycle!

[@freakazoid9276]

Nice to see a review that isn't obviously influenced by a company giving free stuff away. Hard to find genuine reviews anymore. Thanks.

[@JohnEngel]

Thank you so much. Its really nice to see a comment like this.

[@Chris_at_Home]

I have a black and decker 2A mounted on my plow truck. I only do a few driveways in the neighborhood so the battery doesn’t always keep up so I plug it in when done. I like it because it has auto shutoff not like most of the cheaper battery tenders. In my shed where I store toys like snowmobile,atvs and mower I have a small solar panel wired to a terminal strip where I drop through a diode to each battery. The diode prevents one battery draining to another.

Informative video, something to note in addition: longevity and location, these might factor in for some folks. I've had all three and they all got the job done in a heated/cooled garage. None of these are weather proof and from what I've experienced none of these are meant to be outside even when protected from the rain/snow. I lost 2-Schumacher tenders within 3 months in our barn (that is waterproof) charging tractor and mower. Very disappointing and an expensive lesson. Thanks for posting the video, good info/advise.

[@JohnEngel]

Great information. Thank you.

[@carlosw1687]

This is important because you are supposed to charge car batteries in a well ventilated area

[@etow8034]

To the Black+Decker BM3M's defense it is designed to be permanently mounted under the hood as there mounting holes that the other chargers do not have. Rated at 1.2A it actually charges at 1.4A(blinking green LED) and maintains the battery at 300-400mA when completely charged (solid green LED). The physical 6V/12V switch is actually a good feature not relying on the internal circuitry to decide !

[@JohnEngel]

E Tow thank you so much for the comment. I did not know that it was made to be mounted to the car. I can’t tell you that I am still using it but it’s not my favorite one. The Schumachers have been faster and much more reliable.

We hooked up the Schumacher last year and left for 4 months.........when we came back it wasn't on & the battery was dead. Could a power surge have caused the maintainer to disconnect and should have been reset?

[@judyo614]

We are also wondering if disconnecting the battery would be a good idea and hook up the maintainer to it

[@JohnEngel]

Hello and great question. Most of the time if the power goes off, when it comes back on the battery maintainer will just come back on as well. If you have a power surge then the maintainer could have been damaged and that would cause the issue you are speaking of. you can disconnect the battery but that is not needed. I have cars that are on these year round and they are all connected.

Some vehicles have hard to reach batteries. In those cases you can use to the cig adapter to keep your battery charged.

[@ksdad2two]

When it comes to batteries, charging "low and slow" ( low amps, takes longer) will make your batteries last longer.

[@JohnEngel]

I agree. When maintaining the lower amps work best. However if your battery is low then it takes longer to get it back on track.

[@ryanburbridge]

Will an 8 amp charger purchased for my truck hurt the smaller battery of my civic? Thanks

Nope. It will just charge it up quicker.

[@twistof-faith1170]

Using 4 B&D maintainers and 2 of them are almost 10 years old. One is mounted in the truck because it sets for long spells. It's a maintainer and not a charger so the .5 amp is not an issue. Can't get a Standly on Amazon. . . I use one for a deep cycle Battery and inverter for a emergency power in the house, One on the Generator . another is mounted in the truck and one in the mower shed to keep the mower charged over the winter. Ans because they are working so well over time and multi uses. I have another on order to maintain a smaller battery back up for lighting in another building. The longest one in use is going on 5 year of being plugged in. .

[@JohnEngel]

twist of -faith great info. Thank you for the comment.

[@schutztruppe]

what about AH ? I have a 35ah and another 200ah. Is there something to watch out for with these being so different?

[@JohnEngel]

That’s a great question. So Amps/Hour (ah) shows how many amps an hour that charger can send. So the one that can send 200, Theoretically can recharge a battery quicker.

[@davidjames1684]

What people may not realize is that even a large battery (such as 12V 100Ah) should only draw about 0.5 watts so about 40mA (0.04 A) to maintain it when it is completely charged. Also, I doubt the 2A max charger would be much faster than the 1.5A max charger. Reason being the 2A charger will eventually taper down to 1.5A and at that point, the 1.5A charger might still be at 1.5A, so it is only the time between 2A and 1.5A that the "2A" charger would get a "lead". After that, the "lead" will likely not increase. If you plan on topping your car battery off overnight, then I suspect any of these 3 charger/maintainers (and the Noco Genius G750 that this review missed), would all suffice.

[@JohnEngel]

David James very nice write up. Thank you.

[@thurm101]

I have a NOCO .75 amp. I thought that was low but it does the job. I have it hardwired to my battery. My question is can I leave everything connected to car while charging and maintaining

[@GrimYak]

As as maintainer yes, current draw of a locked car with alarm on is up to 0.1 amp. Mine actually activates at 0.1 and sleeps at 0.02. so yes even a 250 mAh tender can mainten the battery provided it was fully charged or close to fully charged in the beginning.

[@pauldow1648]

So do these sense when battery drops below a certain voltage and then charge the battery and then stop at a certain voltage ? Etc. Is this the same as a twinkle charger ? Thanks

[@JohnEngel]

paul dow you are correct. These have the tech build into them to stop and maintain a certain voltage. Almost all are this way now. The old trickle chargers used to keep adding even if the battery was full.

[@alcoury7547]

Informative, Thank You. I have a Prius (Hybrid) can I plug maintainer into lighter? or directly to battery, The owners manual say's to boost the battery do not boost directly to battery (which is in rear) but to connect it to terminal under hood. Which do you think is my best option. Thanks

I now use the stanly it works great.

[@730coderocks]

I may be wrong, and that's fine if you want to use them, but the cigarette lighter port is a bad idea. I don't want to push any amperage through my cars electronics. It is at least going through a fused circuit so In my opinion you could hurt some accessories with that option and I'd just say disconnect the battery and charge it with the clamps.

[@JohnEngel]

Cody Watson most cars I agree with you but the battery on my Viper is behind the driver side rear wheel and you have to take the wheel off and the tray out to get to the battery. This is the only car that I use the cigarette port. I have been using it for over 10 years and so far it has worked. It’s not my favorite method but it works. The new 2020 vette comes with a charger from the factory that uses this method as well.

@@JohnEngel Hey John, many thanks for recommending another Stanley model which I have looked into. I think I will buy what you have recommended but need to pick on your brain again to ensure I get the right product for my purpose, if you do not mind. Background Information: Due to Covid-19, I have been working from home since March 2020. I suspect because of this reason, this is my first time that my SUV car battery died on me back in Aug 2020 when it was only about 3 years old - my past mini van battery lasted about 10 years. I heard about car smart battery maintainer as a solution. My SUV is a GMC Terrain. I like your recommendation for many reasons (i.e. Stanley FATMAX BC8S Fully Automatic 8A 12V Battery Charger/Maintainer with Cable Clamps - Black, 8 Amp). However, I have the following questions if you don't mind answering. (1) What is the "Reverse Connection" feature for / mean? (2) Though it label this model is an "*8 AMP CHARGER", am I right that this device allow me to select "2A" for car battery maintenance purpose? (3) I have looked all over for the length of the electrical cord that plug into the wall outlet of my garage and could not find this information. Assuming the electrical cord that come with the package is not long enough, is it safe to use and extension cord to solve the problem? (4) "....switching to float mode monitoring": am I right to understand this feature mean it will continuously monitor battery level and automatically recharge the battery when it drop below "full" level? (5) "Built-in circuit protection guards against overcharging, reverse polarity, or short circuit; ETL certified for performance and safety". What is "reverse polarity" mean? What is "short circuit" mean? (6) How would I know if the smart battery charger has become defective or near the end of its useful life? I am hoping to be able to place my order as soon as I have your answers and guidance because I cannot get this product locally. Have a great day John.

[@JohnEngel]

@@optimalwin8327 great questions. I’m going to try to answer these as best I can. 1. Reverse connection is if you were to accidentally hook up the positive to the negative. It will detect that you made a mistake and won’t cause a short. 2. You can pick. The 8amp is if your battery was already dead and you needed to charge it quicker. For a battery that is charged you would select 2amp. 3. You can use an extension cord if needed. 4. You are correct. It will automatically do this for you. 5. This just means you don’t have to worry about it shorting out and causing damage to your battery. 6. It most likely will show a red error light.

To prolong battery recycle life, Our engineers of battery charger factory will calcualte time about full charging. such as, 100ah battery, advise 10 hours at leat for charging, so you should choose chager with the biggest 10Amp , or smaller than 10Amp.

The accessory battery on my 2018 hybrid Camry needs to be jumped each day before I can start the car. Last time it was jumped ( yesterday), I drove the car on the highway for 30-40 minutes. I then turned off the car for between 30-60 minutes. It had no trouble restarting so I could drive home. But this evening when I tried to start the car, it wouldn’t start. I need to drive the car in the morning, so I’ll have to jump it again before I can drive. I’d like your opinion; Should I buy a new accessory battery? Should I also get a battery minder?

[@kcb3rd]

Well done. Thanks.

[@GodStang03]

What about Battery Tender?

[@JohnEngel]

GodStang03 don’t have one. Lol

[@JoseRamirez-yh2ll]

This video is like when someone needs to do an essay and they just write a bunch of b/s to get the word count

[@JohnEngel]

Jose Ramirez lmao. Best review ever. I would like to print this one and put it on the refrigerator. Lmao. Thank you.

[@JoseRamirez-yh2ll]

@@JohnEngel ha ha I'm glad you can laugh things out and not take it so serious. So can you tell me if using a battery tender on my car battery, how much more life will or can it extend it?

[@JohnEngel]

Jose Ramirez I see all types of comments and your was great. Yours had some really good humor. I can tell you that the cars I keep on my tenders have twice as long battery life on average.

[@hxhdfjifzirstc894]

Jose Ramirez Thanks for saving me the time. I was suspecting exactly that from the thumbnail.

[@ShinyFenders]

Good info John !

[@JohnEngel]

ShinyFenders Thank you. Trying to up my video skills. Lol

[@ShinyFenders]

John, you can always do the video on how to create the graphics at the beginning of your videos.

[@JohnEngel]

ShinyFenders I used an app called fiver. They made 10 intros for 5 dollars. I supplied the logo and they did the rest. Super easy.

[@ShinyFenders]

Hmmm fiverr.com I like it. Learned something new again. Thanks

[@llineedsadragstrip4089]

no co or deltran ,, im partial they work & dont let me down

[@bbs5400]

with battery tenders, the slower it charges the better it is for your battery during winter

[@davidjames1684]

Not necessarily. Perhaps a slight overcharge is good to produce heat and help melt the ice away. There is such a thing as charging too slowly.

[@q-bert6454]

I bought one of these Stanley chargers and it didn’t even work. Had to return it

[@JohnEngel]

Q- Bert I hope they gave you a full refund. That’s no fun at all. Mine is still going strong but I would make sure that they know that their product was crap out of the box.

[@q-bert6454]

John Engel I got a full refund

[@lornelosier3783]

Hi John, Really enjoyed your video comparaison. I had to by a Battery Charger for my Massey-Ferguson GC2300 equipped with a snow blower and for the 1st time this winter, it refused to start. I had a older model battery charger which I used for one day and it dit the job. However, I just purchased a Schumacher 3A for $52.00 CDN dollars and I am please, once I seen your video, that I bought this model. It also has a cigarette adapter. Question: I have a power boat with two batteries, with an A/B switch. Can I also use it in the summer time, for instance, to charge battery A and then, battery B? Thanks again / Merci beaucoup (french) Lorne Losier

[@JohnEngel]

Lorne Losier thank you so much. I use them Year round and you can just switch the charger between the two. It will make life so much easier. :)

[@lornelosier3783]

John Engel : Thanks very much for your prompt reply. (Merci beaucoup) Lorne Losier

[@leafunpower3207]

Hi Lorne, I want to introduce another kind of battery chargers/maintainer for your interest. www.leafuntec.com

[@ryanburbridge]

So where is the actual testing? I have not found one single actual test between any of the big brands. Just price and advertising lol. I can’t believe no one has hooked up these things to a scope and actually tested these things

[@JohnEngel]

I would like to do this.

[@ryanburbridge]

John Engel and that wasn’t a negative comment directed to you. I have been obsessed lately after replacing two batteries in my truck. I have been reading and watching videos on lead acid batteries. I spent most of my career as a mechanic and still never fully understood the science behind this old technology lol. Now that I’m obsessed i find it really hard to believe no one has actually tested any of these products.

[@JohnEngel]

ryanburbridge none taken. I agree with you and would like to do a video on something more substantial. You came up with a great video idea. Thank you.

[@ryanburbridge]

John Engel i don’t have any scopes but have seen a ton of KZbin videos of people with fancy scopes testing all sorts of things. Just posted a video of me figuring out how to access the individual cells of my new “maintenance free” (LIE) batteries. I have the batteryMinder OBD12 being shipped and will post a video once installed. Keep up the good work. Hate KZbin for censorship but people like you that post quality content keep me around. kzbin.info/www/bejne/jYqUequujcSAjZo

[@JohnEngel]

ryanburbridge awesome. Thank you.

[@BomberandCompany]

Hi John, I have an 08 Bentley Continental GT that sits in the garage for long periods of time. What battery maintainer do you recommend for that vehicle?

[@JohnEngel]

Vincent Ng so the Bentley has a battery charging port in the trunk. If you are looking in the truck it’s on the left wall. Ctek is the brand that came with it. It’s a little more expensive but if you are only buying one, it’s not that bad.

[@BomberandCompany]

[@svtrag]

I thought they were called “battery tenders?” I’m confused.....

[@JohnEngel]

svtrag I received a letter from their lawyer that explained the difference in great detail. Lol

[@svtrag]

Well that’s stupid!

[@GrimYak]

They are but it is also a brand. Im thinking copyrighted too.

[@CrimtideStreams]

I can't find the Stanley 2AMP anywhere.. just 1.5.. can you give a part # or model # for me to find?

[@JohnEngel]

Crimtide I just did a search on Amazon and found they have moved to the 1.5 but you can still find the 2.0 part number Bc209w.

[@CrimtideStreams]

@@JohnEngel Thanks for the info. Do you know of any reason why one should spend more money on the Deltran Battery Tender? I would imagine warranty being 5 years is better than what Stanley can offer.. Not sure about anything else.

[@JohnEngel]

Crimtide I think it all comes down to preference. I used a Deltran about 10 years ago and it did the same as the ones I use now. The warranty is nice because they can go bad after years of use.

[@CrimtideStreams]

@@JohnEngel I think I'll go with the Deltran BT Plus 1.25A .. seems pretty decent, on sale right now too. 5 year warranty as opposed to a 1 year limited on the Stanley. Thanks again.

[@killerdonkey5750]

The Stanley says 1.5 on the website but when it showed up the box had 2 amp on it.

[@haroldprice1030]

Ok then....How does it work?

[@JohnEngel]

Harold Price which one?

[@haroldprice1030]

I'm sorry....how do the batteries get charged up? With a power cord , a solar panel or with a USB cord ? Thanks you for sharing your knowledge . @@JohnEngel

[@JohnEngel]

Harold Price no problem. Thank you for that. All of these are power cord models. I am interested in the solar versions and will get one shortly to see how it does. Thank you again.

[@tranixter]

YO DAYTONA 600 SQUADDDDDD

[@JohnEngel]

Tran A love the Daytona. :)

[@kattmilk]

Is there a similar device that will keep a battery charged w/o having to plug the device into a wall outlet? I don't have a garage & don't think my landlord will allow me to keep the battery charged inside my house; she will view it as a fire hazard.

[@JohnEngel]

I think there are some solar powered ones but I have not had the chance to use them yet.

[@georgejfunderburk7645]

You just reviewed them on cost and convenience features only. Electrical items with no electrical tests. What voltages and currents do they apply to batteries in various conditions? Just a talker not a reviewer.

[@JohnEngel]

George J Funderburk great points. Thank you for your comments. I think you are spot on and I should have done more. Thank you.

[@georgejfunderburk7645]

@@JohnEngel It's still helpful info but only part of what I was hoping for.

[@georgejfunderburk7645]

I bought the Black & Decker because it was available immediately at local store, happy so far after 1 year maintaining motorcycle battery.

[@JohnEngel]

George J Funderburk the black and decker is really nice because you can manually switch between 6 and 12v. Thank you again for the comments and suggestions. I am planning to buy some more and do another video like this so all of the feedback helps make better videos.

[@deanrhodenizer938]

I, too, was a bit disappointed with this review. I presently have a couple of Battery Tender brand maintainers and need a third unit now and was looking for a comparison of how these devices maintain batteries. I searched for "best battery maintainers" and was looking for more in-depth information.

[@kenbarnes8958]

I bought 2 of the b + D. They both died within 6 months.

[@JohnEngel]

I hate that. I would recommend the schumacher but the B&D that I have is still going strong years later.

[@stuffsethmakes]

you don't even pull them out of the box to show us things? c'mon man. jump cuts were a little abrupt, almost like you edited out words you didn't want us to hear.

Stuff Seth Makes good call. This video was subpoenaed for a lawsuit and there was coffee right infringement that had to be removed. The only way to do it was to use KZbin‘s editor and it makes things very abrupt. Good eye though.

[@peterpiper_203]

John Engel Oh snap I found your other video bout the issue Wow what a pile of manure I was a tasking how they held up over the course of the year since you posted the original video My issues are I have a company vehicle So my car truck and sons vehicles sit all week he is at college So I only drive on mine the weekends And start his for 20 mins a week Any help would be appreciated Regardless glad that you got your issues straightened out

[@JohnEngel]

@@peterpiper_203 So far I have had no issues with any of the battery maintainers that I tested during the making of the original video. My favorite budget friendly brand is still the Schumacher as it has the most versatility and ease of use. Any of the three will keep you battery exactly where you need it. Thank you again and sorry about the confusion, the legal aspect is now all I think about when it comes to this video. LOL

[@peterpiper_203]

John Engel Thank you Shame you have to think about that non sense

[@deadzone5389]

The intro shows some promise with mention of sophisticated circuitry to protect, monitor, and maintain the battery -- as well as the possible differences between an $80 unit and one for $5.99. He doesn't touch on that at all, and leaps to "for my cars I've kind of gone middle of the road." Without any real commentary on electrical function this is a kind of long superficial review of $20 units, and which ones have which leads, connections, and mounts. It's not at all about "choosing the right battery maintainer."

[@JohnEngel]

dead zone great points. Thank you so much. I agree with you. I should have given more background. Thank you for pointing that out.

[@rockslide4802]

First of all, there is only ONE brand that is called BATTERY TENDER, the others are battery maintainers. If you are going to talk about Deltran Battery Tenders, you should at least have one on the table. And you completely overlooked CTEK, a leading brand of smart chargers/battery maintainers. The title of your program is wrong, you never displayed a real Battery Tender which by the way comes in many amperages, which include 1.25 amp, 3 amp, 4 amp and 5 amp. Moreover, your title should have included the fact that you are really talking about low to mid cost smart chargers.

[@JohnEngel]

Rockslide great feedback and thank you. I totally agree.

[@davidjames1684]

What happened to the NOCO Genius G750? What kind of 3/4 ass review is this? Also your description states "Selecting the right battery maintainer is easy when you have all the facts!". What about power consumption? You didn't tell me that fact. If I leave a battery on the tender almost 24/7, I want to know how much power it is consuming because that will add up. This review falls short. Downvoted.

[@JohnEngel]

Thank you for your great comment and ideas to help with the next video. I will make sure that I take all of these into consideration. I hate that it upset you so badly.
