Cautions
Please pay attention to followings in case of battery will have leakage, heat etc.
 Do not immerse the battery in water or seawater, and keep the battery in a cool dry surrounding if it
stands by.
 Do not use or leave the battery at high temperature as fire or heater. Otherwise, it can overheat or fire or
its performance will be degenerate and its service life will be decreased.
 Do not reverse the position and negative terminals.
 Do not reverse polarity charging.
 Do not connect the battery electrodes to an electrical outlet.
 Do not short circuit. Otherwise it will cause serious damage of the battery.
 Do not transport or store the battery together with metal objects such as hairpins, necklaces, etc.
 Do not strike, trample, throw, fall and shock the battery.
 Do not directly solder the battery and pierce the battery with a nail or other sharp objects.
 Do not use the battery in a location where static electricity and magnetic field is great, otherwise, the
safety devices may be damaged, causing hidden trouble of safety.
 Please use special charger for charging.
 Please charge the battery within 12 hours after use .
 Charging current should be less than maximum charge current specified in the Product Specification，
Charging current bigger than recommended current may damage the battery.
 Discharging current should be less than maximum discharge current specified in the Product
Specification；Discharging current bigger than recommended current may damage the battery.
 t should be noted that the cell would be possible to be at a over-discharged state by its self-discharge
characteristics in case the cell is not used for long time. n order to prevent over-discharging, the cell
shall be charged periodically to maintain a certain voltage(13.32~13.6)V ,2months one cycle，
Over-discharging may causes loss of cell performance, characteristics, or battery functions. But
for battery packs with commnunication fuction, please maintain it once in 1 month.
 f the battery leaks and the electrolyte gets into the eyes, do not rub the eyes, instead, rinse the eyes with
clean water, and immediately seek medical attention. Otherwise, it may injure eyes.
 f the battery gives off strange odor, generates heat, becomes discolored or deformed, or in any way
appears abnormal during use, recharging or storage, immediately stop charging, using, and remove it
from the device.

 n case the battery terminals are dirty or oxidation, clean the terminals with a dry cloth before use.
Otherwise poor performance may occur due to the poor connection with the instrument.
 Tape the discarded battery terminals to insulate them.
 The lithium ion battery charge discharge shallow is beneficial to improve the cycle life, proposal user
each discharge is put to the nominal capacity of 80%.
 Do not combine the battery pack more than 4 in series and 8 in parallel.

(1)No smoking or fire during installation to avoid short-circuit of battery and prevent equipment damage or
personal injury.
(2)The battery should be installed under a condition with well-ventilated and no sunlight. Don’ t put it under
place with possible flooding.
(3)When fastening battery terminals, please don’ t use excessive force, or the terminals could be damaged.
(4)Use a dry cloth to clean the battery package, please don’ t use oil or other volatile organic solvents to clean
the battery case, or it may damage it.
(5)Please make sure the positive（+） & negative（-） polarity is correct connected, or it may cause fire or damage
the battery or the equipment.

ttery voltage is too low after fully charged.
(1)Battery was in Long-term storage with no used, not in accordance with the provisions for maintenance either.
Solution: Charge the battery can be solved.
(2) Battery suffered fierce collision, with character-External battery case damaged or with electrolyte odor.
Solution: t’ s not in the scope of maintenance generally. f needing maintenance, we need the confirmation of
the problem whether on the output line or the battery itself.
First, open the battery case, check the battery P + / C + and P- / C- lines or joints damaged or not. f damaged, it
needs to be replaced. Then, instigating smell odors method to determine the battery, if there is irritation
electrolyte odor, indicating that the battery has been leaking. You need to test the voltage of each series. f the
voltage of one series is very different with much lower voltage, then this series needs to be replaced.

(1) Battery disconnect
Solution: Remove the battery to check whether the line is broken or not, the solder joints come off or not, nickel
belt breaks or not, and then repair according to the damage situation.
(2) PCB does not work
Solution: First, make sure the cable is contact with the protective board well, and then observe solder is off or
not. f the above conditions are normal, please test voltage between B+B- and P+ P- voltage, then the board
would be failed if the voltage difference is very high. Then please do testing in detail on protection board, if not
pass, please change another new PCB.
