How long will it take for the BatterySAVER PLUS to charge a dead battery?
Depending on battery age, type and condition, the natural rate of loss on a new battery represents a small fraction of one percent per month. The BatterySAVER PLUS is designed to compensate for these losses plus any additional losses due to on board electronic instrumentation such as clocks and alarms. The power generated by the BatterySAVER PLUS is not enough to recharge a dead battery. If you would like to recharge a depleted battery, we suggest that you look at the BatterySAVER PRO15W or larger.
