Li-ion / LiPo Battery Storage and Permanent Capacity Loss

A fully charged Li-ion / LiPo cell is approximately 4.2 volts (3.7 volts under load). Li-ion / LiPo is different from other battery chemistries as it should never be stored fully charged. Li-ion / LiPo should be stored approximately “half full” (40% – 50% of full charge).

Li-ion / LiPo batteries function via a chemical reaction that occurs inside their sealed enclosure. Providing power is a chemical reaction, while the aging/degrading process is another chemical reaction. Chemical reaction doubles its speed for every ten degrees increase of ambient temperature.
