Specification description

Appearance

The surface is clear and is free of scratch, mechanical cuts and match well with the host.

Charge voltage

Nominal voltage

12.8V

Cut-off voltage

Nominal capacity

Minimum capacity

17.5Ah(at 0.2C rate discharge after standard charge)

Standard charge

Step 1:0.3C CC charge to 14.4V;

Step 2: CV (constant voltage 14.4V) charge till charge current decline to 0.02C.

Temperature:0~50℃ 

Max. continue charge current

Max. continue discharge current

6.0A

Operating temperature

Charging: 0°C ~ 50°C

Discharging: -20°C ~55°C
