Battery Care
Storage:
- Bring to ~50 % charge, then store in a cool, dry place
- Do not drop
Charging:
- A CV stage that lasts too long degrades the battery rapidly
- Stand-by applications: exceeding 26.8V degrades the battery
- Charging is disabled below freezing; warm the battery first
- Maximize capacity by regularly charging to the specified voltage
Discharging:
- If no voltage, the battery is off; charge it to wake it up
