Rechargeable Battery Warning

Recharge the battery at an ambient temperature between 5°C and 35°C. Do not recharge for longer than necessary to prevent overheating and bursting. Overcharging or prolonged inactivity may reduce battery life. Rechargeable batteries wear out over time, and their performance will gradually decrease.

To extend battery life, use it until completely discharged before recharging fully. Recharging a partially discharged battery may reduce its lifespan. In such cases, repeat the full charge/discharge cycle multiple times. Avoid recharging the battery overnight.
