Dr. Battery MPL01203P-08 6-cell 11.1V 4400mAh laptop battery

Compatible Acer and Gateway laptops

This 6-cell lithium-ion unit replaces the original battery in a wide range of Acer Aspire and Gateway notebooks. It matches the 11.1V operating voltage and 4400mAh capacity specified by the manufacturer. The black housing fits the existing bay without modification. Buyers who need a higher-capacity pack or a different voltage should look elsewhere.

Straightforward swap with built-in safeguards

Installation consists of releasing the latch, removing the old pack and sliding this one in until it clicks. The on-board smart chip manages charging current, prevents short circuits and protects against overheating or overload. No driver or firmware update is required. Users who expect hot-swap capability or external charging contacts will not find them here.

4400mAh at 11.1V decides runtime

The 49Wh energy rating determines how long the notebook runs on a single charge under typical workloads. Voltage must match the original exactly or the system will not recognise the pack. Capacity fixes the maximum possible runtime for this form factor. Shoppers whose original battery shows a different mAh or Wh figure should verify compatibility before ordering.
