Battery safety and usage
Batteries should be stored in an ambient temperature of -4°F (–20°C) to
67.9°F (+20°C). Lithium batteries will self-discharge during storage, so
they should be fully charged before storage. Self-discharge may affect long
term battery performance. Furthermore, it is recommended that the battery
should be charged in a set time, as below;
Ambient temperature of:
-4°F (–20°C) to 67.9°F (+20°C), once every 6 months
67.9°F (+20°C) to 113°F (+45°C), once every 3 months
113°F (+45°C) to 149°F (+60°C), once every month
Battery should have greater than 50% charge prior to recharge.
The ambient temperature for charging should be 32°F (0°C) to 104°F
(+40°C). If under 32°F (0°C), the battery capacity will be diminished; if
over 104°F (+40°C), the battery may overheat, resulting in permanent
damage.
