Test Conditions

3.1 Standard Test Conditions

3.1.1 Unless otherwise specified, all performance tests is required conducted at temperature 25℃±2℃, Humidity less than 45%~75%RH.

3.1.3 Unless otherwise specified, the tested product is required unused within two month after outgoing.

3.2 Standard Charge Mode

"Standard Charge" means at 25±2℃ charge to limit voltage with 0.33C constant current, then charge with constant voltage until current less than 0.02ItA.

3.3 Quick Charge Mode

" Quick Charge" means at 25±2℃ charge to limit voltage with 0.5 C constant current, then charge with constant voltage until current less than 0.02ItA.

3.4 Standard Discharge Mode

"Standard Discharge" means at 25±2℃ discharge to the cut-off voltage with 0.33C current.

3.5 Quick Discharge Mode

"Quick Discharge" means discharge to the cut-off voltage with 0.5C current.

 

 

Electrical Characteristics & Test Condition.

@Ambient Temperature 25±5℃ & Humidity 45%~75%.

 

NO Items Criterion Condition
1 Internal Impedance ≤30mΩ Test the internal resistance of 50% SOC battery pack with 1 kHz AC internal resistance test instrument.
2 Nominal Capacity ≥98Ah Rest for 1 hour after fully charged, then discharge with 0.33C current until the battery reaches the discharge cutoff voltage. Repeat above process for three times, if the discharge time is not less than 180 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity.

How to choose a suitable battery pack?

  • battery voltage is the same with the original.
  • battery size same with the original. Or similar/smaller.
  • battery plugs same with the original (check the plug diagram)

Match the above three conditions, in general, this battery can be used.

The larger of MAH, the longer use time. Different voltage, battery size, shape, can be same voltage, because the battery combination of different ways, the shape is not the same. You can leave a message about your old battery, please pay attention!!!
