Replacement battery for Acer Aspire laptops
This 6-cell lithium-ion pack operates at 10.8V and delivers 4400 mAh of capacity. It is built as a direct replacement for a wide range of Acer Aspire models including the 4250, 5250, 5733, 5742, 5750, 7551 and 7750 series as well as E1-431 and E1-531 units. The unit is supplied new and carries a one-year warranty from Dr. Battery.
Thermal behaviour and power draw
Lithium-ion chemistry keeps self-discharge low and does not generate noticeable heat during normal charging or discharging cycles. The integrated smart control chip manages charge current to reduce power consumption and extend discharge time. Built-in safeguards protect against short circuit, overheating and overload conditions without adding audible noise.
Build integration and clearance
The battery matches the original form factor so it fits the existing compartment without modifications. No extra cables, mounting brackets or cooling provisions are required. Users should verify the original battery part number and output voltage before installation to ensure correct fitment. It is not suited for laptops outside the listed Acer Aspire compatibility range.

Questions about this item
How is the 6-cell 10.8V battery installed in an Acer Aspire E1-531, and what step is often missed?
Power off the laptop, remove the AC adapter, slide the release latch, insert the pack until it clicks, then reattach the adapter and run a full charge cycle to calibrate the smart chip.
What maintenance or replacement will the 4400mAh lithium-ion pack need over time?
The cells lose capacity with each charge cycle; when run-time drops below usable levels the whole 6-cell pack must be swapped as individual cells are not user-replaceable.
What limit appears first during sustained use of the 48Wh Dr. Battery pack?
The built-in protection chip will cut output if the pack overheats or draws excessive current, so thermal throttling is the first hard limit under heavy load.
