Replacement Battery for Acer Aspire Models
The Dr. Battery MPL01215P-21 is a new 6-cell lithium-ion unit built to replace the original power source in a long list of Acer Aspire laptops including the 5750, 5755, 7551, 7560, 7741G and 7750 series. It delivers 10.8 volts and 4400 mAh capacity for owners who need a direct swap without modifying their notebook.
Fit and Installation Requirements
The battery matches the physical footprint and connector layout of the OEM packs referenced by part numbers such as BT.00603.111, BT.00603.117 and BT.00603.124, so it seats in the existing bay and locks with the original latches. No extra cabling, adapters or firmware updates are required, freeing the user from sourcing proprietary mounting hardware.
Sustained Discharge Behaviour
A built-in smart control chip manages the cells during extended sessions, regulating charge current to reduce heat build-up and lowering self-discharge when the system idles. Protection circuits cut power on short-circuit, over-temperature or overload events, keeping output stable across the full 48 Wh rating rather than fading after a brief burst.
