This "memory" reduces the capacity of subsequent charges and thus future battery life in a given device. The effect can also be caused by poorly-designed chargers. The memory effect can be mitigated by diligent battery use: fully discharging and recharging. One can recondition batteries with a memory effect by deep discharge and charge cycles.
For example, a battery with a capacity of 1000 mAh and a voltage of 3.7 volts would have an energy storage capacity of 3.7 watt-hours (Wh).
