1. Discharge testing harms the battery or shortens battery life. Response: Discharging and recharging a battery is part of the normal battery formation process. Even an inexpensive vented lead-calcium battery (typically the battery type which is most affected by discharge cycles) is easily capable of 40 or more discharge cycles.
The maximum usable capacity that the battery can release as a backup power supply is the most important indicator. It can be seen from the definition of the state of health (SOH) of the battery that under certain discharge conditions, its value is the ratio [] of the capacity released by the battery from the full state at a certain rate to the cut-off voltage and its …
