Storage Guidelines for the Li-Ion Battery
• Use a location at room temperature or cooler. Prolonged storage at higher
temperatures can permanently reduce the charge capacity and performance.
• Ensure the remaining charge is at or near mid-capacity. The charge will slowly drain
during storage. Periodically recharge the battery during storage to ensure it does
not drain to low levels.
