● 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!
Note: To guarantee your personal safety and protect the environment, do not litter the battery! Return the old battery to the mobile
phone manufacturer or place it in specified battery reclamation areas. Do not litter any battery with other rubbish.
Warning: Short-circuits of the battery may cause explosion, fire, personal injury or other severe consequences!
