Nominal Capacity 8.8AH 0.2 C5A discharge
Charging Mmethod
Constant Current Constant current of 1A= 2A Do charge with the specified charger to guarantee not be over-charged and please refer to the charger specification

Constant Voltage Constant voltage of 16.8V ± 0.02
Over-charge Detection Voltage 17.1V± 0.1V Built-in PCB
Over-charge Release Voltage 16.3V± 0.3V The voltage should be d16.3V to allow charging when the function of built in PCB is activated
Over discharge cut – off voltage 9.2V± 0.32V Built-in PCB over-discharge cut-off voltage
Over-discharge release voltage 10.8v± 0.4V The battery can re-start discharge when the function of built – in PCB is activated while the out-put voltage is higher than 10.8V
Standby Current
d35¼ A Power consumption of built-in PCB
Operating current 7A Do not use electronic equipment whose capacity is above nominal operating current
Over-Current Protection 13A The battery output will be terminated when the load current exceeds limit design current
Short Circuit Protection Auto recovered ( respond time is less than 300ms) Clear off short circuit and the battery will work again automatically and the responded time is adjustable.
