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

Inserting or removing battery

Battery compartment is located inside the handle. Turn the cover counter-clockwise to remove. Remove battery for replacement.

Insert the battery (the battery contacts must face into the battery compartment).
