Charge cell with 0.2C to 16.8V then CV to 0.02C cut off; Discharge cell with 0.2C until cell voltage reaches 12V. Repeat to 500 cycles, record remained capacity of 500th cycle. |
Capacity Retention ≥80% of Cmin.. |
| 4.2 Self-Discharge |
After the standard charging, storied the cells under the condition as ambient temperature 23±2 °C for 30 days, then measured the capacity with 0.2C till 12V at 23±2 °C as residual capacity. |
Residual Capacity ≥85% Cmin / |
| 5.1Constant temperatureand constant humidity test |

No explosion No fire No leakage Residual capacity ≥ 60% initial capacity |
| 5.2 Vibration test |
A cell after standard charging and then vibrated for 90 minutes for each of the three mutually perpendicular planes with total excursion of 0.8mm and with frequency of 10 Hz to 55 Hz. | No explosion, no fire no leakage. |
| Test Item | Test Method | Criteria |
| 6.1 Heating Test |
Acell after standard charging, is to be put into an hot box. The temperature of the oven is to be raised at a rate of 5 ±2°C per minute to a temperature of 130 ±2°C and remain for 30 minutes. |
No explosion No fire Temperature≤150ºC |
| 6.2 Overcharge protection |
After the battery is fully charged, use constant current constant voltage source to continue to load the battery 8h, constant current constant voltage source voltage is set to 2 times the nominal voltage, the current is set to 2.0C external current |
No fire, no smoking ,no explosion. The over charge protection function should be started. |
| 6.3 Over discharge testing |
At standard testing condition,the cells be discharge to 12V according to the requirements of standard discharge, then connect with external load of 30 ohm for 24 hours. |
No fire, no smoking ,no explosion. The over charge discharge function should be started. |
| 6.4 Short-circuit Test |

9. Battery operation instruction
9.1 Charging
9.1.1 Charging current:Cannot surpass the biggest charging current which in this specification book stipulated.
9.1.2 Charging voltage:Does not have to surpass the highest amount which in this specification book stipulated to decide the voltage.
9.1.3 Charge temperature:The battery must carry on the charge in the ambient temperature scope which this specification book stipulated.
9.1.4 Uses the constant electric current and the constant voltage way charge, the prohibition reverse charges. If the battery positive electrode and the cathode meet instead, can damage the battery.
9.2 Discharging
9.2.1 Discharging current The discharging current does not have to surpass this specification book stipulation the biggest discharging current, the oversized electric current electric discharge can cause the battery capacity play to reduce and to cause the battery heat.
9.2.2 discharge temperature:The battery discharge must carry on in the ambient temperature scope which this specification book stipulated
9.2.3 Over-discharges:After the short time excessively discharges charges immediately cannot affect the use, but the long time excessively discharges can cause the battery the performance, battery function losing. The battery long-term has not used, has the possibility to be able to be at because of its automatic flashover characteristic certain excessively discharges the condition, for prevented excessively discharges the occurrence, the battery should maintain the certain electric quantity.
9.3 Storing the Batteries
The battery should store in the product specification book stipulation temperature range. If has surpasses above for three months the long time storage, suggested you should carry on additional charge to the battery.
10.Period of Warranty
The period of warranty is 12 months from the date of shipment. Guarantees to give a replacement in case of cells with defects proven due to manufacturing process instead of the customers abuse and misuse.
11. Other The Chemical Reaction
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the batteries cannot maintain a charge for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery.
