reference
Battery is recommended to use the original charger charging,
charging time not more than 5 hours, the use of poor quality
charger or charging time is too long, are easy to make the battery
damaged.
The first 3 charge should be put to recharge by 10% to completely
activate the battery! Do not charge only a small amount of
electricity to avoid shortening the battery life and capacity.
If the machine is not a long time please at least a month for the
machine to avoid an electric charge, the battery performance
Note:
1.To ensure that the battery maintains the capacity level, it is
recommended that the battery and battery pack be stored at -0 ~ 35
° C, low humidity, and non-corrosive gas.
2.Avoid storing the battery in high temperature or high humidity,
otherwise it will cause battery leakage, rust, and low capacity.
3.Long-term storage may cause the capacity of the battery and
battery pack to decrease, and it will take 1-3 charge / discharge
cycles to reach the maximum discharge capacity.
4.The battery needs to be charged and discharged once after three
months of storage. To avoid over-discharging the battery, it must
be stored under power.
5.The battery is over-discharged for an instant and then charged
immediately without damaging the battery. However, the battery will
be damaged if it is discharged for a long time.
