which may affect the service life of the battery or damage the internal circuit, or
even cause danger.
When the battery is short of power, it should be charged in time, which is
beneficial to extend the battery life. If the battery is not charged in time, battery
is in the state of power shortage for a long time, battery life will be affected.
The lithium-ion battery charge and discharge shallow is beneficial to improve
the cycle life. Suggest user each discharge be put to 80% of the nominal capacity.
6.5. Battery Using and Maintenance
The battery would be possible to be at the over-discharged state by its self-
discharge characteristics in case the battery is not used for long time. In order to
prevent over-discharging, the battery shall be charged periodically to maintain
a certain voltage range: 13.32 V~13.6 V, 2 months one cycle. (for battery with
communication function, please maintain it once in 1 month) What's more, the
SOC/ capacity calibration shall be performed. The calibration method is to
charge fully with charger, then discharge to over-discharged protection state.

6.6. Battery Common Troubles and Solutions
Battery voltage is too low after fully charged.
Battery is in long-term storage with no usage, and not maintenance in
accordance with the provisions.
Solution: Please test the battery voltage. If the battery voltage is <8.0 V, it can't be
charged and need to be isolated. Please consult the technicians. If the voltage is ≥
8.0 V, the battery can be isolated to charge, and periodically check to see if it can be
charged normally.
Battery Disconnection
Solution: remove the battery to check whether the line is broken or not, the welding
joints come off or not, nickel belt breaks or not, and then repair according to the
damage situation.
Protection Board not work
Solution: first, make sure the cable line is contact with the protection board well,
then, observe welding is off or not. If the above conditions are normal, please check
the voltage between B+/B- and P+/ P-, the protection board has been broken if the
voltage difference is very high. Then please do testing in details on protection board,
if not pass, please change another new protection board.
