Terminals

F1

Housing material

ABS (acrylic butadiene styrene)

Maximum discharge current

68 A (5 c)

Internal resistance

15 mOhm

Operating temperature range

Discharge: -40 ~ 60 °C, Charge: -20 ~ 60 °C, Storage: -40 ~ 60 °C

Addiction Cном. from °C

40 °C - 103 %, 25 °C - 100 %, 0 °C - 86 %

Charge voltage

Буферный режим – 4.5 - 4.6 V, Temperature coefficient -6 мВ/ ˚С, Cyclic mode – 4.8 - 5.0 V, Temperature coefficient -10 мВ/ ˚С

Maximum charge current

1.35 А

Self-discharge

Могут храниться to 6 months at 25 ˚С, after which a charge is required. Higher temperatures reduce shelf life

Life time

8 years in buffer mode или более 260 cycles заряда-разряда в циклическом режиме, at 100% discharge

*The battery must be charged before use. At higher ambient temperatures, storage time is reduced
