Maintaining the battery
To help maintain the performance and life of the Li-Ion battery,
understand and follow the guidelines below:
• Recharge the battery frequently, preferably after each use or at
night. Limit the number of full discharges, if possible.
• Frequent use at high temperatures can reduce performance.
• Use a dry location at or near room temperature when storing the
battery for an extended time. Prolonged storage at higher
temperatures can reduce performance.
• Ensure the remaining charge level is at or near mid-capacity when
storing for an extended time. The remaining charge will slowly drain
during storage. Periodically charge the battery to ensure the
remaining charge does not drain to low levels.
