Mastering Battery Reserve Capacity: A Detailed Guide
The reserve capacity (RC) quantifies the time a fully charged battery can deliver 25 amps of current before falling below 10.5 volts. Higher RC means longer operation before the charge depletes. For instance, a battery with a 200-minute RC can deliver 25 amps for that duration. RC greatly affects the discharge rate.
