【Design Life】

2700 cycles @ 70% Depth of Discharge (DOD) at 25℃

3800 cycles @ 50% DOD at 25℃

5900 cycles @ 30% DOD at 25℃

【Operating Temperature Range】

Nominal Operating Temperature: 25℃ (77℉)

Discharge: -20℃ to 50℃ (-4℉ to 122℉)

Charge: 0℃ to 40℃ (32℉ to 104℉)

Storage: -20℃ to 40℃ (-4℉ to 104℉)

【Recommended Charge Conditions】

1. Daily energy storage

   - 2.42+/-0.02 VDC/Unit at 25℃, current limit 0.07CA (84A) (CC-CV)

   - 2.42+/-0.02 VDC/Unit at 25℃, current limit 0.07CA (84A) (Multi-step)

2. Power fluctuation control

   - 2.42+/-0.02 VDC/Unit at 25℃, current limit 0.14CA (168A) (CC-CV)

【Self Discharge】

Less than 10% after 90 days, can be stored up to 6 months at 25℃ (77℉);

Fully recharging is required before usage, and charged sooner if stored at higher temperature than 25℃ (77℉).
