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 positive 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 the location where static electricity and magnetic field is great, otherwise, the safety devices may be damaged, causing hidden trouble of safety.
Do not overload with battery
Please use special charger for charging.
Please charge the battery within 24 hours after fully discharged.
If 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.
If 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.
In 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.

Battery Checking

After receiving the battery, you should first check the packing carefully. During the handling process, please ensure there’s no shock on the battery.
Please check the battery case and accessories if there’s any damage or leakage, if so, please contact us immediately.
Please check the output connector is correct or not, measuring the voltage between positive and negative, if it’s within the normal standard.

Installation and Precautions

No smoking or fire during installation to avoid short-circuit of battery and prevent equipment damage or personal injury.
The battery should be installed under the condition with well-ventilated and nonlight. Don’t put it under place with possible flooding.
When fastening battery terminals, please don’t use excessive force, or the terminals could be damaged.
Clean the surface of battery with dry cloth, please don’t use oil or other volatile organic solvents to clean, or it may damage it.
Please make sure that the positive (+) & negative (-) polarity is correct connected, or it may fire or damage the battery and load.
Start testing the equipment if it could be well working with battery.
Using and maintenance

Battery Using and Maintenance

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.
Discharge temperature:-20℃~+60℃.Humidity:RH≤85%.When the temperature is higher than 45℃, please note ventilation. When the environment humidity is higher than 85%, please pay attention to protection. Charging temperature:0℃~+45℃.Humidity: RH≤85%, When the environment humidity is higher than 85%, please pay attention to protection; storage temperature: 0℃~40℃ (Best temperature is 15℃~25℃ in dry environment). Temperature affects the capacity of battery obviously, it’s normal.
When the battery power is low, please charge it in time. This could ensure longer cycle life. If the battery can’t be charged in time and let it under power shortage condition, it may affect the cycle life.
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%.
It should be noted that the cell would be possible to be at the over-discharged state by its self-discharge characteristics in case the cell is not used for long time. In order to prevent over-discharging, the cell shall be charged periodically to maintain certain voltage range 13.2V~13.6V , 2months one cycle Over- discharging may causes loss of cell performance, characteristics, or battery functions. But for battery packs with communication fuction, please maintain it once in 1 month.
Don’t use organic solvents to clean the battery case. If for battery fire accident, please use dry powder fire extinguisher or sand.
Battery is a consumable product with limited cycle life. Please charge it in time when the capacity can’t reach the requirement to avoid any loss of the user.

Battery Common Troubles and Solutions

Battery voltage is too low after fully charged.

Battery was in long-term storage with no usage, not in accordance with the provisions for maintenance either. Solution: charge the battery can be solved.
Battery disconnected 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.
Protection circuit does not work Solution: first, make sure the cable is contact with the protection circuit well, then, observe solder is off or not. If 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 circuit, if not pass, please change another new protection circuit.
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 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, indicating that the battery has been leaking. You need to test the voltage of each series. If the voltage of one series is very different with much lower voltage, 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 soldering 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 soldering condition, the battery needs to be unpacked to be welded again.
Protection circuit abnormal Solution: replace the protection circuit.
Connector or terminals in poor contact condition Solution: replace the terminals or connectors
Battery works properly in charging but could not discharge or discharging well but could not charge. Solution: The protection circuit is damaged; you need to replace the protection circuit.
