2. Deep cycle lithium ion battery 12V 40Ah performance

NO. Items Criteria Testing method
4.1 Rated Capacity 40Ah 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 120 minutes, you can stop and define the Discharging current*time value (Ah) as battery capacity.
4.2 Minimum Capacity 40Ah
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 0.33C until it can’t discharge, and then rest it for 1h. Charge the battery following CC(0.33C)/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.
