How the heck do I replace the battery!

[stevenole08]

This is embarrassing, but removing the battery has been a nightmare. I pulled up the carpet in the trunk, those push pins were nasty. I am struggling mightily getting the plastic sheath off of the positive terminal. I have pulled the tabs on the plastic on both sides. Had to use an allen key since my hands are too big. And I removed what I thought were the nuts holding it down. I can wiggle it a bit now, but I'm terrified to force it and break it. I'll attach a pic, but has anyone done this themselves? My battery is dead dead and calling to get this towed would be ridiculous.

I haven't trted but from what I've seen, it's not user friendly. Good luck. Don

Just hooking up a battery tender wire to the terminals was a piece of work. Very tight spaces.

I would install a battery tender under the hood using the remote terminal.

I had to jump my FJ the other week and I was puzzled under the hood. I had to go back home and look at the manual...

This is how I did my CTS-V and C6 Z06 (both rear-battery cars).

Why would you remove it just for being dead? You can use the lugs under the hood to jump/booster box or connect a charger. I installed a NOCO on board battery maintainer under the hood. Can't even tell its there when not in use.

How did you install the battery tender under the front hood? I am referring to the little loops on the tender. I know I can aligator clamp them both but then the hood will be propped open since the red/positive post is in an odd spot, and the clamp sticks straight up. The negative post is way to big for the little eyelets

You can remove the black plastic shroud on the positive jump terminal. It's just two plastic clips. With that off, you can put a tender on and then close the hood.

Doesn't prevent it from going dead, probably just extends it's death date. Don

LOL, Don...of course it prevents it from going "dead", that is PRECISELY the point of installing one on a car that is used infrequently. The more sophisticated ones do extend the life of the battery, but that is secondary to keeping the battery in a healthy state of charge and ready to go when the weather says its OK to drive precious.

You have a recommendation for a battery tender? Thanks, Don

I've always used the (Deltran) battery tender. I've had various models and am currently using two of the 1.25A battery tender plus units.

I have one of those but always considered them to be a charger not a maintainer. Don

CTek is the way to go. And they both charge and maintain. Steps 7 and 8 both do long term maintenance.

The Cadillac and Corvette OEM chargers (what you get if you option the Battery Protection package) are rebranded CTEK units.

For many years I been using Pro Charging Systems marine chargers on my AGM batteries. My Jeep battery is 8 years old and have been using the charger when parked in the garage. Obviously since it’s for marine, water is not an issue and you could use it outside.

Had Cteks before and gave up on them. They will not bring a battery back from a deep drain, simply not enough Amps.

FWIW, my Z06 has spent six Winters and my Blackwing three Winters on the OEM maintainers and are fine. Tens of thousands of Corvette owners are using the OEM maintainers and I assume a non-zero number of Cadillac owners are doing the same. The idea is to put the cars on the maintainers when they aren't going to be driven for several weeks so that you don't overly drain them.

I use the Schumacher maintainer. Attached a quick plug in the trunk directly to the battery.
