What safety precautions should I follow regarding the battery?

Do not charge the battery pack using any method other than the specified one, and never throw the battery into fire or subject it to physical shock. Do not disassemble or modify the battery pack, and avoid short-circuiting the terminals, water exposure, or leaving it in high-temperature environments. The battery is a consumable item and its lifespan is not covered under the standard product warranty. (Page 2)
