trickle charger

Here are my experiences with battery maintainers.

1999 Corvette and 2007 Pace Car both used Battery Tender Junior with 0.75 Amp - OK for early models but cannot maintain newer cars with all of the battery drain when stationary. Note that the 2007 was on tender for 18 months during Covid when I did not drive the car and all was good when I eventually started the car.

Now for my 2017 Grand Sport I needed to up the ante - Motomaster Simple Series 3 Amp - works fine. Also second one for 2012 Lincoln Corsair when go south for 3 months in January. All sourced from Canadian Tire. On the C7 I had to modify the connection to the car by adding a cigarette lighter connection to the wires connecting the charger to the battery and then plug it in to the full time receptacle in the trunk. The C7 battery is in the trunk without easy terminal access. No big deal.

Never had a problem with my C7 using the OEM product with designated outlet in rear trunk. Looks the same as the one I have for my C8. Previous corvettes - 79, 96, and 2003 CT product, I believe?

A note of caution re use. C7 must be connected via the connection in the back. [ trunk area ].
The connection in the front, [ cig. lighter ] shuts off after 10 mins when car is turned off !!
Thus using that connection you get 10 mins of 'charging'.
The rear connection operates even when car is turned off.

Yes, exactly. I always plugged in because every time I returned to the garage. I did not drive for 2 wks and my battery was dead. Ditto C8 .
