To guarantee the optimal performance of your battery, please stick to the following rules:
Use only the battery provided by Aspera. Otherwise, damage or even injuries could be caused during
charging. You may also void the warranty.
Power off the mobile phone before removing the battery.
The charging process lasts a longer time for a new battery or a battery not in use for long. If the battery
voltage is too low to enable the mobile phone to be powered on, charge the battery for a longer time. In
this case, the battery icon does not flicker until a long time after the battery enters the charge status.
During charging, ensure the battery is placed in a room temperature environment or in an environment
close to room temperature.
Immediately stop using the charging process if the battery produces odor, overheats, cracks, distorts or
has other damage, or if the electrolyte leaks.
The battery wears out with use. A longer charging time is required as the battery is put into use for a long
time. If the total conversation duration decreases but the charging time increases even though the battery
is properly charged, purchase a standard Aspera battery. Using any poor-quality fittings will cause harm
to your mobile phone and may be dangerous.
Note: To guarantee your personal safety and protect the environment, be careful if disposing of the battery.
Return the old battery to Aspera or place it in specified battery reclamation areas. Do not dispose of the
battery with normal household waste.
Warning: Short-circuits of the battery may cause explosion, fire, personal injury or other severe
consequences.
