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.
