Dr. Battery MPL01246P-28 laptop battery 11.55V 4670mAh

Replacement Battery for Acer Aspire S13

The Dr. Battery MPL01246P-28 is a new lithium polymer battery built to match OEM specifications for the Acer Aspire S13 S5-371 series. It delivers 11.55V and 4670mAh capacity, providing 53.9Wh of energy for compatible ultraportable notebooks. Buyers who need a different voltage or a higher capacity pack cannot use this unit.

Fits Directly Into Existing Chassis

This battery slots into the original compartment without adapters or cable changes, freeing the user from carrying an external power bank. The integrated smart control chip manages charging and discharge cycles while the pack supplies power to the motherboard exactly as the factory unit did. Builders looking for a modular hot-swap solution or a secondary battery bay will not find that capability here.

Sustained Output With Protection Circuitry

Under continuous load the smart chip regulates current to prevent short circuit, overheat and overload conditions, keeping voltage stable across the discharge curve. Quicker charging and lower power consumption extend usable runtime between wall charges during long work sessions. Users who require detailed cycle-count telemetry or software-adjustable charge thresholds are not supported by this hardware.
