Keep it plugged in?
I have a 2015 i8 with the original 12 V battery and I want to make it last as long as possible. Since battery access is problematic, a battery tender is not practical. I think I heard on Pat‘s Garage Online that keeping the car plugged in trickle charges the 12 V. I have been leaving the car plugged in, but I’m wondering if I’m doing it any good, or harm?
Opinions?
