GM Accessories 84020220 Battery Conditioner with Crossed Flags Logo, Black

This is the OEM battery tender that GM sells for use with the C8 Corvette. I'm sure it's used with other vehicles too, but the C8 has a plug in its "frunk" that this plugs into. Very easy to use and it works great. I received it in a nice package, just like you'd get if purchased at a Chevy dealership.I highly recommend this tender for your C8 or any other vehicle with a cigarette lighter type plug that can be used to charge your battery.

I have a 60th Anniversary Edition, Grand Sport. I need my baby properly cared for during the winter months and GM Battery Condition is part of that equation. Worth the money, great buy and a must have!!Randy W.

It works great as a keeps my racecar ready to go!

Got this to maintain battery on a 2021 Camaro that does not come out of the garage over winter. Nice solid unit. Battery on these cars is hidden in trunk and inaccessible. Problem is, the cigarette lighter socket is not energized when the car is shut down, so plugging this into cig socket to maintain battery is pointless. I returned it. Nice unit, expensive, and not useable for my application. Returned.

My battery kept dying over the cold winter months while my C7 was sitting in my garage. The conditioner is a little pricey, but I understand why it's at the price point it's at. It's been working well for me so far. One thing I suggest is to put a towel down over the trunk edge, then put the conditioner wire on top of that so that you can close the trunk.

Was exactly what I was looking for.

Had to replace my old one I ran over!! Great charger for Corvettes..

Great Product and Excellent Knowledge and Customer Service.
