I. Precautions

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.
It 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. In order to prevent over-discharging, the cell shall be charged periodically to maintain a certain voltage(15.6~16)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.
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.
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%.

II. Battery Installation Guide

1. Battery check

After receiving the battery, you should first carefully check the packaging. During the process, please ensure that the battery has no electric shock.
If there is any damage or leakage, please check the battery box and accessories, and if so, please contact us immediately.
Please check whether the output connector is correct and measure the positive and negative voltages and voltages to see if they are within the normal standard range.

2. Precautions

Do not smoke or catch fire during the installation process to avoid short circuit of the battery and prevent equipment damage or personal injury.
The battery should be installed in a well-ventilated and sunless place. Do not place it where flooding is likely.
When fixing the battery terminals, do not use excessive force, otherwise the terminals may be damaged.
Use a dry cloth to clean the battery components. Do not use oil or other volatile organic solvents to clean the battery compartment, otherwise the battery compartment may be damaged.
Please make sure that the positive (+) and negative (-) polarity of the connection is correct, otherwise it may cause fire or damage the battery or equipment.

3. Battery installation

Clean the battery installation location to ensure that there is no dust or mental objects.
Put the battery in the right place
Connect the terminal between the device and the battery well.
After connection, please check whether the connection is good, the positive and negative poles are reversed, and there is no dust or debris.

III. Battery care and maintenance

1. When the battery is low, please charge it in time. This can ensure a longer cycle life. If the battery cannot be charged in time and is in a state of lack of power, it may affect the cycle life.

2. The battery should be installed in a dry, clean environment with air circulation. Avoid using flammable materials during charging/discharging.

3. Use temperature: -20℃~+60℃. Humidity: RH≤85%. When the temperature exceeds 45℃, please pay attention to ventilation. When the ambient humidity is higher than 85%, please pay attention to protection. Charging temperature: 0℃~+45℃. Humidity: RH≤85%, when the ambient humidity is higher than 85%, please pay attention to protection; Storage temperature: 0℃~45℃ (optimum temperature 15℃~25℃ in dry environment). The battery is affected by temperature and can be displayed by the capacity change, which is normal.

4. Do not use organic solvents to clean the battery compartment. In the event of a battery fire, use a dry powder fire extinguisher or sand.

IV. Common battery faults and solutions

1. The battery voltage is too low after being fully charged.

The battery has not been used for a long-term storage and does not meet the maintenance regulations.

Solution: Charging the battery can be solved.

The battery collides violently, the battery casing is damaged or the electrolyte smells.

Solution: Generally not within the scope of maintenance. If maintenance is required, we need to confirm whether there is a problem with the output cable or the battery itself. First, open the battery compartment and check the battery P + / C + and P / C wires or connectors for damage. If it is damaged, it needs to be replaced. Then, instigate the smelly odor method to determine the battery, if there is an irritating electrolyte odor, it indicates that the battery has leaked. You need to test the voltage of each series. If the voltage of a series is very different from the much lower voltage, the series needs to be replaced.

Insufficient capacity

Solution: It usually takes 3-5 cycles to charge and discharge the battery.

2. After the battery is fully charged, the battery voltage is zero or low (the charger shows that it is full).

Battery disconnected

Solution: Remove the battery, check whether the circuit is damaged, whether the solder joint is off, whether the nickel band is broken, and then repair it according to the damage.

PCB not working

Solution: First, make sure that the cable is in good contact with the protective plate, and then observe whether the solder is closed. If the above conditions are normal, please test the voltage between B + B- and P + P- voltage, if the voltage difference is large, the circuit board will fail. Then please conduct a detailed test on the protection board. If it fails, please replace it with a new PCB.

3. Unstable battery voltage

Welding error

Solution: Use an internal resistance tester to test the resistance, and confirm whether the internal resistance of the battery exceeds a predetermined value. Otherwise, the welding state of the battery will be wrong, and the battery needs to be disassembled and welded again.
