Addiction Cном. from °C
40 °C - 103 %, 25 °C - 100 %, 0 °C - 86 %
Charge voltage
Буферный режим –2.25-2.30 W/El., Temperature coefficient –3 мW/El./˚С., Cyclic mode –2.35-2.45 W/El., Temperature coefficient –5 мW/El./˚С.
Maximum charge current
0.3 С
Self-discharge
≤3% в month at 25 ˚С. Могут храниться to 6 months at 25 ˚С, after which a charge is required. Higher temperatures reduce shelf life
