8.1 Battery Maintenance
Keep the both sides of coin cell clean.
- Low temperature may decrease the performance of coin cell, and low
battery indicator may appear early. In such case, please put coin cell
into pocket for warm before use, thus bring it back to normal condi-
tion.
- Do not let any conductive metal (such as tweezers) contact both sides
of coin cell simultaneously to avoid short circuit.
- Charge the coin cell for 8~10 hours each time; ambient temperature
should be 5°C~40°C.
- If the coin cell is full after charging, but its performance decreases
apparently, it means the coin cell is exhausted, please change a new
one.
