Battery Capacity

WUBEN ABD4800 4800mAh 21700.
Capacity (IN) 2.96V > 4.156V: 4080mAh*

No Data Found

 * Actual capacity (input) value will be higher if cell is being charged from 2.7V to 4.2V.
From our experience, placing a USB tester with the charging line would result in earlier charging termination(0.3V~0.5V) than direct plugin.
