I'm about to put my GSh in storage for a very long time since I drive a company-provided vehicle now. I have never used a battery maintainer and after doing a bunch of research, does amperage matter if it's just maintaining the battery? Can I hook the battery maintainer while the battery is connected to the vehicle?

Yes, I've been using a Battery Tenders on my lawn mower and my muscle car for years. One will charge a low battery and then kick over to trickle-maintenance mode. The other will only maintain an already charged battery. I get 6 years out of a lawn mower battery and I got 12 out of my last battery in my muscle car.

No, amperage doesn't matter unless you are trying quickly charge a battery. I've even used the cheapy wall wart models from Harbor Freight with good success.

I've been using my Battery Tender since 1995.

Awesome. Thank you both!

What matters is not the amperage. But a quality one like a Ctek to ensure no damage to the battery or the cars electronics. Which on a hybrid is very expensive if you blow anything.

You are correct. It is the XM ID 😁

I have the Optima tender and would recommend it. It will also do the Optima batteries and small motorcycle ones.
