When I keep my fully charged spare battery in the car, dose it stay fully charged over time?
Mine seem to lose their charge. I pop them onto my desktop charger for about 15 minutes each week to top them off.
Storing batteries at full charge limits their life. Optimally you should store a Li-Ion/Polymer battery at 50%. Otherwise you should just swap your batteries every few days to promote their useful life.
