For those of you that don't have the factory built in battery maintainer, I could use some suggestions on what aftermarket maintainers that you are using. Thanks
The C7 does not have a built in battery maintainer. GM offers a rebadged aftermarket unit that just plugs into the cigarette lighter port.
Any of the aftermarket units work just as well as the GM badged unit, including the $9 float charger from Harbor Freight.
EDIT: I just got a new flyer from Harbor Freight and their float charger is $5.99 with a coupon(plus you get a free LED flashlight with any purchase, a $6.99 value).
A lot depends on your parking situation, enclosed home garage or carport, parking deck, or in the driveway. My situation is an open air carport. I didn't want to put the battery maintainer shut up in the trunk of my vert, and didn't want it in the open humidity of the carport. I use a Deltran Battery Tender that's located in a utility room and have a 25 foot lead extension to the vert trunk.
Edited to add that battery maintainer brands are a personal choice. I've used several different ones and never had a problem with any.

I have the vette maintainer and it is no different than the ~$20 shumacher and black & decker maintainers that I have used successfully for years. Except the ~$20 ones come with the clips as well as the cigarette lighter adapter.
I've used a Deltran Battery Tender Plus on my car for years and have been very pleased with its performance.
Same here, used on my 2006, 2008, 2010, and now my 2014 with zero issues and always provided a quick start in the Spring.
Nice to see the green LED glow in my garage in the middle of a Minnesota winter as the Vette hibernates.

I would highly suggest the CTEK MUS4.3 which is an 8 step battery maintainer. They are available at Amazon for under $80.00 and if you want to use the maintainer for plug-in to the rear cargo outlet, order the cigarette lighter adapter.
The CTEK US3300 that GM sells only has one mode (car mode) while the CTEK MUS4.3 has a motorcycle mode, car mode, AGM mode, cold weather mode, and recondition mode.
I use the CTEK brand on 4 of my 5 vehicles.

I use the harbor freight float charger on my vette and tundra. Question for U guys more knowlegable than me. I put this same float charger on my zero turn mower and it killed the battery, I tried two different float chargers twice and it did the same thing. Anyone know why this happened? Thanks

Most likely the low priced chargers "boiled" the battery. You need a quality charger. Although you saved money on the low priced chargers they cost you more in replacing batteries.
The low priced chargers can't measure the voltage they are putting into the battery causing them to over charge and destroy the battery.

Would it not boil the bigger vette and tundra battery or is because the mower battery is smaller. I have a friend who uses the same HF float charger on his mower with no issures. Go figure
