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.
Battery Installation and Replacement
