general information

[Design lifespan]

400 cycles at 100% discharge depth (DOD) at 25 ℃ and 1800 cycles at 30% discharge depth (DOD) at 25 ℃

[Operating temperature range]

Nominal working temperature: 25 ℃ (77 ℉), discharge: -15 ℃~50 ℃ (5 ℉ 122 ℉), charging: -15 ℃~40 ℃ (5 ℉ 104 ℉), storage: -15 ℃~40 ℃ (5 ℉~104 ℉)

Certification

IEC 60254-1:2005/IEC60254-2:2008

Balanced charging voltage

14.4-15.0 VDC per unit, 25 ℃ (77 ℉)

Self discharge

After 90 days, the self discharge should not exceed 10% and can be stored at 25 ℃ (77 ℉) for up to 6 months; Before use, it is necessary to fully charge. If the storage temperature is above 25 ℃ (77 ℉), it needs to be charged earlier.
