In this video I show you how to replace the battery in your 2010 Toyota Corolla S.

Now before you flip out on me YES I did hook up the negative terminal first. NO it won't harm anything. If you don't feel comfortable doing it that way then just hook up the positive first. The only reason you usually hook up the negative last is to prevent arching with your wrench. (yes I messed up showing it like this) Honestly there is nothing that gets in the way on this car so your chances of arching are pretty low unless you are using a 36" long wrench. Thanks for watching!

    My friends positive side of the battery terminal cable got cut (eaten by a squirrel we think) . How do I fix that ?

    What is the size of the Corolla battery cable? 2AWG or 4 AWG +

    Good video Eric & I think I can save you some money. I'm a Power EE with experience in connections from low voltage up to 500KV. The purpose of the grease within the connection & external to the connector is solely to keep the environment (salt or polluted air) from the micro ridges caused by the scratch brushing the inside of the connector & the battery terminals. So any cheap non-conductive grease will work e.g. Vaseline etc. In the power industry the mantra is Scratch brush & grease then torque to specification. This works for all voltages up to 500KV, AC or DC. A lot of electrical connections are palm to palm so it's counterproductive to file these surfaces flat. Scratch brushing creates thousands of micro ridges that carry the current, so protect those micro connections with non-conducting grease then don't over tighten the connector (don't strip the thread). Cheers.

    Oh no, he called us "YouTube" again! And he had come so far. O well, everybody slips once in awhile. Great video btw, and thanks for sharing.

    I had a friend help me replace my battery, so I technically didn't see where he unhooked it from. I later saw a tiny hole which I would assume it hooked into. He said it "wouldn't reach" and told me it just has to hook "somewhere"…. ummm…. I would like to put it back where it's supposed to be. So is that where it actually hooks back into?
    This part of the video was left out. Thank you for the help

    Isn't water conductor 🤔 and if you replacing the battery why bother cleaning the old one ?

  7. Avataaar/Circle Created with python_avatars David Bergman says:

    Hi Eric, can you tell me if anything needs to be reset in the ECM after the battery is removed and replaced on a 2017 Toyota Corolla or can I just do what you did in this video and it should be good to go? Thanks

    Good job

    Eric I have never had luck getting those thin hold down come off. They usually break. 😩

  10. Avataaar/Circle Created with python_avatars MrBilldodd says:

    What I am unable to do is hook the J Bolt to the battery tray. Exceptionally frustrating.

  11. Avataaar/Circle Created with python_avatars Andy Au says:

    Great video. Very informative. Do you know if this method works on a 2016 Corolla? Specifically the spraying of the battery. I'm not worried about the battery, more like Toyota switching parts and plugs from 2010-2016.

  12. Avataaar/Circle Created with python_avatars Pat Jago says:

    My experience is when you get corrosion on your terminals it’s time for a new battery.Don’t bother cleaning and putting back the old battery. The corrosion will most likely come back. Plus you could get stranded somewhere with an old dead battery.

  13. Avataaar/Circle Created with python_avatars gravethebeyond says:

    clean the terminals with diet coke.

  14. Avataaar/Circle Created with python_avatars GNX157 says:

    An upgrade suggestion would be to get a heat shield blanket installed around the new battery. Will help long term durability.

  15. Avataaar/Circle Created with python_avatars Frank Newling says:

    Always connect the positive first. No need to worry about the wrench or any other possible shorting because the battery is not part of the circuit without a ground.

  16. Avataaar/Circle Created with python_avatars kamdaddypurp says:

    How does this person never look at their battery that was a lot of corrosion lol

  17. Avataaar/Circle Created with python_avatars Duncan Mac says:

    Thanks for the video.

  18. Avataaar/Circle Created with python_avatars not ready says:

    Great demo, terrible angle

  19. Avataaar/Circle Created with python_avatars Ami Kingdon says:

    Just did this today! Great explainer.

  20. Avataaar/Circle Created with python_avatars Justin Ching says:

    I didn't pay much attention to the disconnect, but you reconnected the batter cables incorrectly.

  21. Avataaar/Circle Created with python_avatars NURUL AZIM says:

    Thanks for the video. Today I changed my 2014 corolla battery with the help of your video. The + and – thing is little confusing though.

  22. Avataaar/Circle Created with python_avatars hong lan le says:

    YOU DID GOOD JOB, THANKS FOR YOUR VIDEO CLIP

  23. Avataaar/Circle Created with python_avatars Robert Hurley Jr says:

    Isn't there danger or short circuit computer parts by spraying?

  24. Avataaar/Circle Created with python_avatars Ceasar R. says:

    Brand fuckin new! Thank buddy👍🏼 great video.

  25. Avataaar/Circle Created with python_avatars John Lewis says:

    oh man the OCD in me wont let me use those sprays on the terminals. It just made that nice new battery dirty. I just rub a light coating of dielectric grease on mine being careful not to get it on the battery.

  26. Avataaar/Circle Created with python_avatars Renzo Arce says:

    Is it natural that after I put back the terminals and cleaned the battery the car starts up kind of weak 🤔 is it normal?

  27. Avataaar/Circle Created with python_avatars Bread Knight says:

    is this a magic trick?

  28. Avataaar/Circle Created with python_avatars All Around Flat says:

    thanks

  29. Avataaar/Circle Created with python_avatars daniel jovanovski says:

    nice of you

  30. Avataaar/Circle Created with python_avatars Get It Done says:

    same way! nice! the only little difference, i put 1:4 ratio of baking soda solution (water) in a bottle. but i guess, i am going to use your technique more often now. 🙂

  31. Avataaar/Circle Created with python_avatars MacmanJim says:

    Thought when installing battery you connect positive first then negative ?

  32. Avataaar/Circle Created with python_avatars Geo Jor says:

    thanks…

  33. Avataaar/Circle Created with python_avatars Μαθητής Λυκείου says:

    You can use scotch brite to clean the terminals or metallic toothbrush…with contact cleaner and for anti corrosion vvp grease (vaselin based waterpoof)and mil c 85054 amalgard or mil c 81309!-_^
    Good job !regards from Greece from corolla g6 vvti.2001

  34. Avataaar/Circle Created with python_avatars Gary's Garage says:

    Didn't think I would learn anything about changing a battery, I was wrong. Great video. I never thought of using water and baking soda to clean corrosion. Thanks, Gary

  35. Avataaar/Circle Created with python_avatars ourlegacy says:

    Excellent demo. Two suggestions: 1) as noted: Remove negative battery clamp first and positive battery clamp last. Reconnect positive battery terminal connector first and negative battery connector last. 2) No grease b/t the battery posts and clamps because we want clean dry electrical mating surfaces for low resistance. Grease/coating/spray only over secured terminals to prevent corrosion.

    Do you install a battery saver to keep from losing your presets?
