If overcurrent at power on is detected or a short circuit occurs, unplug the battery, then check
if there are foreign objects in the port. If under-voltage at power on is detected, charge the
battery before use.
If the battery temperature is abnormal, wait for the temperature to return to normal. The
battery will then automatically power on or resume charging.
For other situations, after resolving the issue (overcurrent, short circuits, excess battery voltage
due to overcharging, or excess charging device voltage), press the power button to cancel the
LED indicator protection alert and unplug and plug in the charger again to resume charging.

• DO NOT charge the battery near ammable materials or on ammable surfaces such
as carpet or wood. DO NOT leave the battery unattended during charging. There should
be a distance of at least 30 cm between the battery station and any charging batteries.
Otherwise, the battery station or charging batteries may be damaged by excessive heat
and this may even lead to a re hazard.
• The battery temperature will be high after ight. Wait to charge the battery until it cools
down to room temperature. Otherwise, charging may be disabled. Charge the battery at
a temperature range of 0° to 60° C (32° to 140° F). The ideal charging temperature range
is 22° to 28° C (72° to 82° F). Charging within the ideal temperature range can prolong
battery life.
• DO NOT immerse the battery in water to cool it down or when it is charging. Otherwise,
the battery cells will corrode causing serious damage to the battery. The user accepts full
responsibility for any damage to the battery caused by immersing the battery in water.
• Regularly check the terminals and battery ports. DO NOT clean the battery using alcohol
or any other ammable liquid. DO NOT use a damaged charging device.
• Keep the battery dry during charging.
