Replacement Battery for Acer 4250 Series

This 6-cell lithium-ion battery replaces the original pack in Acer 4250, 4251, 4252 and 4253 models. It is built with grade A cells and rated at 48Wh, 4400mAh and 10.8V. The unit is new and intended for owners whose factory battery no longer holds a useful charge.

Capacity and Runtime Limits

A 48Wh pack delivers a finite amount of energy per cycle; actual run time varies with screen brightness, processor load and attached peripherals. The cells are rated for up to 500 charge cycles before capacity drops noticeably. Heavy workloads will drain the battery faster than light office tasks.

Installation Notes and Common Issues

The battery slides into the standard compartment and locks with the existing latch; no tools are required. First use should include a full charge and discharge cycle to calibrate the fuel gauge. Buyers who need a higher-capacity 9-cell pack or an external power bank will not be served by this 6-cell unit.
