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.
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: 13.32V~13.6V, 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.
 Don’t use organic solvents to clean the battery case.
 Battery is a consumable product with limited cycle life. Please change it in time when the
capacity can’t reach the requirement to avoid any loss of the user.
 In order to prevent the safety problem caused by the failure of the protection board overcharge
protection function, do not charge for a long time. After the battery is fully charged, remove it.
In addition, use the original charger or the one attached to the battery and operate it according
to the instructions. Otherwise, the battery may be damaged or cause danger.
 The shallow charge and discharge of the battery ensures that the battery can be used
economically. Overcharge and over discharge may cause the battery overheat, fire or function
failure, shorten life, or other dangerous.

Battery Common Problems 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 <8.0V, it can't be charged and need to
be isolated. Please consult the technicians. If the voltage is ≥ 8.0V, 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.
Battery suffered fierce collision, with character-external battery case damaged or with electrolyte odor
Solution: It’s not in the scope of maintenance generally. If needing maintenance, we need the
confirmation of the problem whether on the output line or the battery itself.
First, open the battery case, check whether the battery P + / C + and P- / C- lines or joints damaged or
not. If damaged, it needs to be replaced. Then, instigating smell odors method to determine the battery,
if there is irritation electrolyte odor, indicate that the battery has been leaking, and need to test the
battery voltage of each series. If the voltage of one series is quite different from others or much lower
than others, then this series needs to be replaced.
Insufficient capacity
Solution: To charge and discharge the battery with 3~5 cycles generally.
Battery voltage instability or cannot charge or discharge normally.
Faulty welding
Solution: To test the resistance with the internal resistance tester, and confirm the internal resistance of
the battery exceeding a predetermined value or not. If not, the battery would be in faulty welding
condition, the battery needs to be unpacked and be welded again.
Protection board abnormal
