3.2 Discharge

Note that the positive and negative (poles are not reversed as indicated by the battery case logo), then connect to the matching load.

4. Battery Test

Single-cell and Protection board specifications are only results of standard tests, this is for reference.

4.1 Standard Test Requirements

All tests in this specification should be done in standard atmospheric conditions. (Temperature: 25± 2℃; relative humidity:65± 20%).

The standard charge voltage is  14.6±0.2V, the standard discharge cutoff voltage is about 10V; the standard current is I2 (when I2 > the normal work current, test according to the normal current).

4.2 Standard Charge

Charge the battery with Lithium-ion battery special test cabinet, with standard charging voltage, standard current, constant current, and constant voltage charging to the current dropping to 0.05 I5·

4.3 Standard Discharge

Discharge the battery with a Lithium-ion battery special test cabinet, discharge to standard discharge cutoff voltage with standard current, constant discharging, or until the battery stops.

5 Battery Use Environment Requirements

Battery discharge ambient temperature is -20 ℃~ + 60 ℃ (When the ambient temperature is>45℃, please pay attention to the ventilation and heat dissipation), and Charging temperature is 0 ℃~ + 45 ℃. Ambient humidity RH is ≦ 85%. Pay attention to waterproof when ambient humidity is > 85%, at the same time the battery surface condensation phenomenon should be avoided.

6 Special Attentions

In order to make full use of the energy efficiency of the battery and prevent accidents such as leakage or heat generation, please prohibit the following:

◆Do not immerse the battery in the water. Once it is in the water, isolate it immediately and ask a professional to deal with it.

◆Do not charge, discharge, and leave the battery at temperatures over 60℃. Also keep away from fire, heaters or corrosive materials. Otherwise, it can cause overheat, fire, or function failure, shortened life, or even danger happening.

◆Do not charge the battery at a temperature below 0℃.

◆Do not reverse the positive and negative terminals. Do not short the positive and negative of the battery.

◆Do not combine the battery in series or in parallel.

◆Do not reverse polarity charging. Do not connect the battery electrodes to an electrical outlet.

◆Do not transport or store the battery together with metal objects such as hairpins, necklaces, etc.

◆Do not strike, trample, throw, fall or shock the battery.

◆Do not directly weld 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 the magnetic field is strong. Otherwise, the battery protection circuit may be damaged.

◆Do not overload the battery.

◆Do not machine the circuit board, which may damage the internal circuit and cause function failure. 

◆Do not deform the product under pressure, which may cause electronic components or part of the circuit damage, and make the product unstable.

◆Do not remove the case, in case of unnecessary damage.

◆Do not overcharge or overcharge the battery.

◆Please use a special charger for charging.

◆Please charge the battery within 12 hours after using. If the battery is not charged for more than 12 hours after use, please test the battery voltage before charging. If the voltage of the battery is <10V, do not charge, need to place in isolation.

◆If the battery leaks and liquid splashes into the eyes or skin, do not rub it, wash it with clean water, and immediately seek medical attention.

◆In case of an accidental fire, a dry powder fire extinguisher or sand should be used.

◆If the battery gives off a strange odor, generates heat, becomes discolored or deformed, or any abnormality appears during use, storage, or charging, stop charging and using immediately, remove and isolate it from the device in the safe way.

◆The electrode of the discarded battery terminal should be covered with insulating paper to reduce the safety hazard when laying aside.

◆Reversing the Positive and negative charging terminal will burn the internal circuit board, so pay attention to it.

7 Battery Using and Maintenance

7.1 Battery Storage

Storage temperature 0℃～40℃(Optimum storage temperature 15℃～25℃, dry preservation). Battery performance is affected by temperature, the most obvious is the change in battery capacity, this is normal phenomenon. Avoid condensation caused by temperature changes during storage, otherwise it will lead to the rust of batteries or metal parts.

7.2 Battery Checking Before Using

◆After receiving the battery, first check the packing carefully, please ensure there’s no shock on the battery during the handling process.

◆Please check the battery case and accessories if there’s any damage or leakage, if so, please contact us immediately.

Please check whether the output connector is correct or not, measure whether the positive and negative is reversed, and whether the voltage is within the normal standard. In case the battery terminals are dirty or rust, clean the terminals with a dry cloth .

◆before use. Otherwise, poor performance may occur due to the poor connection with the instrument.

7.3 Battery Installation Notes

◆Please clean up the installation position of the battery to ensure no dust, metal, or other foreign materials. 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 of well-ventilated and no sunlight. Don’t put it under place with possible flooding. The using and storage of the battery should be kept away from inflammable and explosive materials

◆When fastening battery terminals, please don’t use excessive force, or the terminals could be damaged.

◆After installation, please check whether the terminal fastening is in place and whether there are sundries on the surface of the battery. 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 correctly connected, or it may fire or damage the battery and electrical appliances.

◆Test to run the equipment, observe whether the equipment and battery are abnormal.

7.4 Battery Working Requirements

◆The charge and discharge current of the battery shall not exceed the specified maximum charge and discharge current, which may affect the service life of the battery or damage the internal circuit, or even cause danger. 

◆Discharge current shall not exceed the specified maximum discharge current, which may affect the service life of the battery or damage the internal circuit.

◆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 about 80% of the nominal capacity.

7.5 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:13V-14V, 2 months one cycle. ( for battery with communication function, please maintain it once in 1 month) What's more, the SOC/capacity.
