3. 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 1.0C constant current, then charge with constant voltage until current less than 0.02C.

3.3 Quick Charge Mode

"Quick Charge" means at 25±2℃ charge to limit voltage with 1.0C constant current, then charge with constant voltage until current less than 0.02C.

3.4 Standard Discharge Mode

"Standard Discharge" means at 25±2℃ discharge to the cut-off voltage with 1.5C current.

3.5 Quick Discharge Mode

"Quick Discharge" means discharge to the cut-off voltage with 3.0C current.

4. Product Performance

NO. Items Criteria Testing method
4.1 Rated Capacity 10Ah Rest for 1 hour after fully charged, then discharge with 0.5C current until the battery reaches the discharge cutoff voltage. Repeat above process for three times, if the discharge time is not less than 120 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity.
4.2 Minimum Capacity 9.8Ah
4.3 Internal resistance ≤40mΩ 50% battery SOC state frequency of 1 KHZ ac resistance tester
4.5

Cycle life

(DOD100%)

≥2000cycle Discharge with the current of 0.5C until it can’t discharge, and then rest it for 1h. Charge the battery following CC(0.5C)/CV(14.6V) mode to full capacity, and then rest it for 1h. Repeat above process until full charged capacity is no more than 80% of normal value. Accumulated times is defined as cycle life.
