Battery Charging and Care
• Power Off First: Always turn off the light before starting the charging process.
• Access the Charging Port: Gently lift the rubber cover to reveal the USB
charging port.
• Connect the USB Cable: Plug the USB cable into the charging port securely.
• Choose a Power Source: Insert the other end of the cable into a wall adapter,
power bank, or computer USB socket.
• Monitor the Charging Indicator: The charging process begins when the
indicator shows a Flashing Blue light. Once fully charged, it will change to Steady
Blue.
• Unplug When Fully Charged: Disconnect the USB cable once the battery is fully
charged to prevent overcharging and extend battery lifespan.
Battery Care
• Voltage Safety: Do not charge the battery with more than 5V, as it may cause
damage.
• Fire Hazard Prevention: Keep the battery away from flammable materials
while charging to reduce the risk of fire or explosion.
• Temperature Considerations:
o Battery temperature may rise significantly during charging (up to 40°C).
o After approximately 300 charge/discharge cycles, the battery capacity
may decrease to around 80% of its original capacity.
o Cold temperatures impact battery performance:
▪ At 0°C, capacity decreases by 5-10%, reducing runtime by 50%.
▪ At -20°C, capacity may drop by 30%, leading to a 70% reduction in
runtime.
o The battery will return to normal performance once it reaches 20°C
again.
• Proper Storage: Store the battery in a cool, dry place when not in use. To
maintain optimal performance, fully recharge the battery at least every three
months.
