When 0% is displayed, recharge the power bank fully (100%), and then fully discharge (0%).
After about 5-6 cycles, the display will show the normal battery level.

Note:

1, Don't use pointed batteries. Batteries with damaged appearance are not use.
It is not recommended to use the battery with high internal resistance, long storage time and many times of use.
2, Only 18650 flat-head batteries can be used, and the voltage is in line with 3.2V-4.2V. You need to use brand new batteries. Old batteries and damaged batteries will cause failure to work.
3, Incorrect connection of positive and negative poles, will burn out the circuit board.
4, The first time you need to use the battery full.
5, Charging power depends on your device, for example: 9V-2A, if your device supports 9V-2A, then it will automatically jump to 9V-2A, if not, it will not jump.
