A recent ACL reconstruction has had me down for several weeks, and the battery in the Boxster, which I suspect was nearing end-of-life to begin with, is nearly dead. There was enough juice to lower the window when I opened the car door manually, but I'm going to buy a new battery this weekend.
I know it's advisable to keep power to the car when the battery is removed, either through the fuse panel or with a cigarette lighter adapter/charger, but would it hurt anything to simply keep my trickle charger connected to the battery leads when I remove the battery? Would that provide sufficient juice to keep the DCM and radio from going whacky? Any concerns with doing this?
Electrical is my weak point...
Thanks!
