What it is and who it fits

The Dr. Battery MPL01231P-15 is a new lithium-polymer replacement battery rated at 2200 mAh and 15.2 V, delivering 33 Wh. It is built for owners of compatible Acer Aspire, Chromebook, TravelMate Spin, V3 and ES series notebooks who need a direct swap for the original pack.

The voltage and capacity that decide fit

The pack supplies 15.2 V and 2200 mAh, matching the OEM specification for the listed models including A515-51, A517-51, E3-111, E5-771, ES1-311, ES1-411, V3-111 and TravelMate Spin B118. Verify your original battery part number and output voltage before ordering because many similar-looking Acer units use different electrical ratings.

Behaviour during a full work session

A built-in smart control chip manages charging current to reduce heat build-up and extends usable discharge time across a full day of typical office tasks. Integrated protections against short circuit, overheat and overload activate automatically under sustained load, keeping output stable until the cell reaches its safe low-voltage limit.
