Corrosion on Your Car / Truck Battery? Cleaning Tips! It’s Important!

You may find some dusty green or brown corrosion on your battery, especially near the terminals or metal tie downs. If you discover this, it may be the result of an overcharge condition, undercharge condition, or excessive venting of the battery. This video shows you how to clean the battery up, why you should, and other places to check for additional corrosion, like the terminal ends and wires, that could cause more problems with your electrical system, even after you replace a battery!

Female who has always been dependant on others to help with car issues. Unfortunately most people think they know BUT THEY DONT KNOW what their doing! These videos are just perfect me and others who are just learning. Thank you so much. Amazing...

[@newttella1043]

You are correct! Dudes don't want to admit to how clueless they are so they just charge ahead with a "fix".

[@annasimmers9549]

Ditto

[@jeffreymeeks4051]

I recently graduated from automotive school and I can attest to the accuracy of this channel. Among all of the car gurus and supposed experts throughout youtube, 1A Auto gives accurate, detailed information on many veihlce issues. Much of what they discuss are concepts I learned in school.

[@Chris-mo9gt]

As someone unhappy with the help I rely on from selfless ppl these videos help me no longer need them. 😂

OMGGGG SAME HERE 🙌🏼THANK GOD AFOR THEIR VIDEOS 😊

*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*

[@brandongiroux7448]

Definitely the best teacher on this channel. For those who aren't full red seal mechanics, he makes things simple and direct. Thanks man!

[@johnhynal6633]

Gotta admit at 77 years that a red headed stranger could teach me anything about battery maintenance that I didn't know. Duh... Best presentation ever! Thanks.

[@johnl9135]

I keep forget why the terminal keep getting corrosion and came here to refresh my memories, but at the same time got info how to properly cleaned the battery too. Great info, thanks.

[@ronaldkorte8094]

When cleaning the tops of the batteries, I always plug the holes with rubber stoppers to keep the cleaner out of the internals of the battery. Has always worked well for me.

[@Carlostype]

The best battery maintenance video there is! Never thought of contaminants getting to the cells

I just realized i usually click 1A Auto’s videos when it comes to car issues and have been doing it for nearly 10yrs. Damn

[@AngelTorres-pm9yl]

Lol! “You do you boo boo…” I’m in love. Brains, brans and sas! 😍 Thank you for this. Gonna work on my battery 🔋 tomorrow.

[@cornpop7805]

Thank you for taking the time to help people with their cars! I'm a lifetime electrical guy and I would like to add: Voltage doesn't flow, current flows. A lot of people like the water analogy, so let's use that. Voltage would be analogous to pressure and just assume whatever the device that requires Voltage, is already designed for that Voltage (pressure) too little or too much voltage to the device, can cause issues. However, current that flows to devices, can vary depending on certain factors. For instance, your stereo will use less current when the volume is low and more when the volume is high. Windshield wipers: less current on low than high, etc. You battery delivers more current (flow), through the cable, the more devices it's powering, could be: headlamps + radio + wipers + defrost. The alternator is wired in parallel to the battery, so it powers items, or shares the load, when the engine is running.

[@agostinodibella9939]

I never heard of corrosion of the different terminals due to different over or under charge conditions. That’s interesting. Very cool test with the LED bulb to show the small current drain on the top of the battery! I never saw that before, which really makes you think about keeping the battery clean! Excellent video overall!

[@helpisonthewaytutoring4259]

This is a great video! So informative and detailed yet easy enough for someone with little experience to understand. I especially appreciate the explanation of the causes of corrosion. The fact that I have corrosion on the positive terminal and the illustration of the need to take the battery out helped me decide to wait 2 days and get my voltage regulator checked vs. tackle the cleaning myself. Thanks for the helpful content!

[@Josephplaysrblx]

Blippi meets car mechanics. Loved this video and your energy!

[@indycog]

I love this guy! I knew half the info but kept watching for his moxie.

[@benmcclure85]

You broke this down in such a simple and useful way for people who aren't mechanics to understand! This is an excellent guide.

[@inner_kundalini]

This is absolutely THE BEST video on battery care. I understand now so much more about batteries and care, and so clearly. Thank you sincerely 💚💚💚💚

[@MrBigbear1684]

One observation that I made was as the battery nears its END OF LIFE their increased off gassing from the battery and subsequently the top of the battery is "moistened" with acid from the battery and the corrosion increases at an alarming rate on both terminals but mostly on the positive terminal.

[@davidlummus4833]

I love seeing your videos! I need to do the cleaning of my battery terminals, but just because of how fun and informational this was, I even want to show my fiance! Thanks guys!

Dielectric grease does not conduct electricity. It simply has a greater water resistance than standard grease

[@gns2550]

i hear people say electrical tape conducts electricity too

[@ms79ta]

Thank you for the extra knowledge. Battery in my car never does this but my F-150, the one with all the brains (😁) , has given me issues with corrosion on the positive post. You're very thorough and easy to learn from. 👍

[@igork.2271]

Thx man, the most accurate and precise tip about cleaning battery corrosion. You helped me a lot.

[@robertnewman4105]

Great info! I've been cleaning the terminals about 2 or 3 x a year and it never had much corrosion. But now doing some winter prep, I've got some blue build up corrosion. Cleaned it and going to have it checked further soon.

[@chadhoes606]

This was great. Got a new battery yesterday. Terminals were very corroded. I thought the guy did everything necessary when replacing it, but the battery died again. So I get to get up early tomorrow and use what I learned here to clean those terminals. He tested the starter and alternator and said they tested fine.

[@idmhead0160]

Installed a new battery for you and didn't even bother cleaning the terminals? I'm assuming you mean the connectors?

Question: why didn't you clean the area where the battery sits on-it was very dirty? Felt like you should it up after cleaning the battery so nicely. Thanks

My dad was a NY certified mechanic and all around petrol head, who also owned a gas/repair shop. Dialectric grease is good, however you can also simply apply vaseline around the battery terminal and leads before reattaching everything. Seems to last 2-3 years here in the NE, which is probably about when one would need to do some basic PMCS on a battery anyways. Since I have Permatex Anti-Seize, I use that which also works very well.

[@1AAuto]

+Boots Thanks for the feedback!

[@johnjohns2333]

I use a Vaseline coated fabric washer under the terminals when the battery water is topped off in each cell and the top is sealed and cleaned.
