Finished battery can not occur scratches, smudges, deformation, discoloration, leakage and other undesirable phenomena.
2, the warranty period
12 months warranty from the date of the factory code.
Lithium batteries should be kept in a cool, dry, ventilated environment, avoid contact with ignition sources and heat.
Battery specifications basis having the specified temperature range for storage, optimum storage temperature 0-25 Celsius, optimum humidity of 60 ± 25%.
Batteries should be stored at room temperature, should be charged to 40-60% of the electricity. To prevent excessive battery discharge, it is recommended every three months according to the standard charging method on a single charge, such as storage for more than a year, the proposed annual standard way of charging and discharging a charge and discharge cycle to activate the battery.
To ensure proper use of the battery, please read the instruction manual before using.
Do not dispose in fire.
The battery charger can not reverse polarity.
Can not short circuit the battery.
Avoid excessive shock and vibration battery.
Do not disassemble or distort the battery.
Can not be immersed in water.
The battery can not be with other types and models of batteries.
Keep out of the reach of children.
Please use the appropriate charger to charge the battery.
Do not use beyond the specification maximum charging current to charge the battery.
Charging voltage: Do not exceed the maximum specified in this specification charging voltage.
Charging temperature: Batteries should be within the specified temperature range for charging and discharging.
Please use the constant voltage charging mode, do not reverse the positive and negative, to avoid damage to the battery.
Discharge current does not exceed the maximum rated discharge current specifications. Large current will cause the battery to generate heat and reduce capacity.
Discharge Temperature: Battery must be within the specified temperature range specification discharge.
Over-discharge: The battery charge is then instantly put off immediately without damaging the battery. However, if the long put, the battery will be damaged. In the long-term storage, it may be because the battery self-discharge and cause the battery is over-discharge state. Therefore, in order to avoid excessive battery discharge, must live storage.
