Warnings & Precautions
Charging
Use Compatible Chargers Only. Do not use chargers designed for Li-ion or Lead-Acid batteries.
Never exceed the maximum charge voltage of 5.0V.
Avoid charging at temperatures below 0°C or above 45°C.
Discharging
Do not short-circuit the terminals. High short-circuit current can cause overheating and terminal damage.
Ensure proper ventilation around the battery during operation, especially in enclosed fixtures.
Storage
Recharge every 6-12 months during storage to compensate for self-discharge and prevent capacity loss due to sulfation.
