Gianni has it wrong. Other way round, undo the negative first so if the spanner touches the body/engine nothing happens, as its a negative to negative connection. With the negative disconnected then undo the positive, if the spanner then touches the body/engine the negative is already off so you don't short the battery out. If you use Gianni's method and start on the positive, then with one end of the spanner on the positive, if the other end touches any bare metal it will try to weld itself to your car. Scheesh, the c**p some people write.

Thanks for the video ! Gave me full confidence changing mine and the mechanic double checked and said I did it perfectly. All thanks to your video ! 🎉 Cars running great now

I would disconnect the negative terminal before I do anything else on the battery. I don't want to blow up any fuse or damage any electronic components. Your ratchet almost touched the battery positive post at 3:25.

You also don't need to loosen the back Bolt that is on the rod just the front one then the rod will unhook

I should have watched and listened to your direction before I tried to exchange the new battery for my 2017 RAV4. Because I just dropped the thin holding rod backside of the battery into the deep down the "crevasse", I had to get rid of the bottom plate for the battery to reach the "rod" stuck inside the narrow-open space. lol. 😅 So as soon as loosening the backside holding nut, you have to put the long thin rod away from the unwanted dropping by accident. haha. Thanks for the detailed explaination.

Dude you almost grounded out that ratchet on the battery bracket with the Positive terminal on the battery

I have a Costco battery too

What about computer issues?

NO! Remove the NEGATIVE CABLE Before doing ANYTHING ELSE! Then REVERSE order with Negative Cable on LAST! THST IS THE SAFEST WAY.

You NEVER remove any parts at or around the battery, you FIRST disconnect the negative terminal and move it aside. Period. Dropping tools or parts around the battery may cause shorting between the terminals, possible exploding the battery or starting a fire. Had this happen at our shop, due to poorly trained trainee mechanics. Dangerous in this video. Don't do it that way.

I would never replace the battery cables without cleaning them and applying anti corrosion. That’s why your cables and bolts are corroded.

13mins ??????

Incorrect way to unhook battery neg post 1st then positive then unscrew the tie down.

When replacing a battery, remove the positive first and then the negative. When installing, you do the reverse.
