Installation with Included Tools

The package supplies four screwdrivers and an instruction manual for removing the bottom cover and swapping the cell pack. Common issues include hidden screws under rubber feet and fragile ribbon cables that tear if pulled at an angle. Disconnect the old battery connector before lifting the mainboard to avoid shorting the pads.

Sustained Runtime and Cycle Life

The pack is rated for up to 1000 charge cycles using grade A cells that maintain charging speed over time. Built-in protection guards against over-charge, over-discharge, over-temperature and short-circuit events during long sessions. UL, CE, FCC and RoHS certifications confirm the safety circuitry remains active under continuous load.
