Replacement for Acer Aspire models
The Dr. Battery MPL01215P-22 is a 6-cell lithium-ion battery rated at 10.8V and 4400mAh. It serves as a direct replacement for a wide range of Acer Aspire laptops, including the E1-431, E1-531, E1-571, E1-731, E1-771, V3-771, and V3-771G series. It also matches original part numbers such as BT.00604.049, BT.00605.062, BT.00605.065, BT.00605.072, BT.00606.008, and BT.00607.125.
Drop-in fit for listed notebooks
Installation requires no tools beyond those needed to access the battery bay on the compatible Acer chassis. The pack supplies 48Wh of energy through the existing connector, freeing the user from a tethered power adapter. It is not suited for ultrabooks or models outside the extensive compatibility list, nor for systems requiring a different voltage or cell configuration.
Steady output under continuous use
A built-in smart control chip manages charge cycles to deliver consistent voltage during extended sessions, reducing the sharp drops seen in worn cells. Protection circuits guard against short circuit, overheat, and overload conditions, allowing the pack to sustain its rated capacity over long discharge periods. The chemistry is optimised for daily cycling rather than occasional standby use.

Questions about this item
How long does the 4400 mAh capacity last before the voltage drops under continuous load?
The 6-cell 10.8 V 4400 mAh pack delivers 48 Wh; run time depends on the laptop's power draw, so a 20 W system would run roughly two and a half hours before the voltage sags.
Does the built-in smart chip keep the pack cool and quiet during all-day operation?
The smart control chip manages charging current and provides overheat protection, so the battery runs silently and stays within safe temperature limits during extended use.
Which original Acer battery part numbers must match for this replacement to fit?
It replaces Acer part numbers BT.00604.049, BT.00605.062, BT.00605.065, BT.00605.072, BT.00606.008 and BT.00607.125 — verify yours matches one of these.
