Dynamics Hong Kong Limited RINGVIENTO Manual De Usuario

-15- 

To guarantee the optimal performance of your battery, please stick to the following rules: 

‹  Use only the battery provided by the vendor. Otherwise, damages or even injuries could be caused 

during the charging. 

‹  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 the charging, ensure the battery is placed in a room temperature environment or in an 

environment close to room temperature. 

‹  Immediately stop using the battery 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 battery from the OEM or use a battery approved by 
our company. Using any poor-quality fittings will cause harm to your mobile phone or even incur 
danger!
