2 Battery Usages


2.1 Charge

Charging terminal of battery is connected tochargerappropriate with it, and then charge. Charging voltage is14.4±0.15V. Do

not reverse.


2.2 Discharge

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


3 Battery Test

Single cell and Protection board specification are only results ofstandard test,this is for reference.


3.1 Standard Test Requirements

Battery tested must be done within 1 month after production. If the battery is not tested on time due to transportation or other reasons, the battery can be recharged and discharged for testing.

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

Standard charge voltage is 14.4±0.15V, standard discharge cutoff voltage is about10.0V; standard current is I5 (when I5 > the normal work current, test according to the normal current).


3.2 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 ·


3.3 Standard Discharge

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


4 Battery Service Environment

Battery discharge ambient temperature is -20°C ~ + 60°C (When the ambient temperature >45°C , please pay attention to the ventilation and heat dissipation), Charging temperature is 0°C ~ + 45°C . 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.
