Hi. I'm Mike from 1AAuto. We've been selling auto parts for over 30 years!

We're going to remove the battery. These battery hold downs ā€“ they're long bolts, I can just slide this harness off of this one. They look pretty rusty. I'm going to spray some rust penetrant on them before I try to move them. I'll let that sit and now I can start by disconnecting the negative terminal, which is 10mm, and for this one, just loosen it up. It doesn't take much, just put that aside.

This terminal here doesn't look factory, it could be a 10mm on your car. This one looks like it's been switched to a 12. Loosen this up, and just wiggle it free. Put the harness aside.

Work on getting this bracket out, and use a 10mm deep socket, and a ratchet, and just remove these two. Actually, you don't even have to thread these all the way off. Once you get them loose enough, they are sort of hooked in at the bottom, and you can unhook them. Take up this hook. Once you've got one unhooked, you can unhook the other.

Be careful, don't touch, as you're doing this. Don't touch any metal between these two terminals because they are live, you'll short it out. You don't have to thread the nut all the way off of these, because that'll take forever. Just get them loose enough and unhook them. With the battery tie down removed, can take the battery right out of the car. It's got this plastic cover on it, I'm just going to pull it off so it's easier to grab. I'm going to reach in with my hands and grab it. This battery's pretty small. Just put that aside.

When your battery is sitting here in the battery tray, these little hooks go in on either side. That's how they hold down the battery. When you loosen them, you're just undoing them, sliding them out and pulling them up.

We're going to take this tray out of here, so it'll give us more room. While this tray is out, you can clean it, if you like, with mild soapy water.

Place our plastic battery tray back in place. Reinstall the battery, make sure the wires are out of the way. Reinstall the plastic cover. This wide opening goes towards the front. Get that in place.

Take the battery tie downs, get them hooked. Tighten those down.

Iā€™m going to reinstall the positive terminal, so that actually goes over that. Put that down there. This one is a 12mm. When you're tightening this one, just make sure you don't touch the end of the wrench to ground, because this is the live terminal. Couple turns, make sure it's tight. Now you can reconnect the negative. This one happens to use a 10mm. Tighten that up. There you go.
