Dr. Battery MPL16230P-27 6-cell 10.8V 4400mAh laptop battery

Replacement battery for Toshiba Satellite series

This 6-cell lithium-ion unit replaces original Toshiba batteries across the Satellite A, C, L, M, P and U families. It delivers 10.8 V and 4400 mAh capacity, matching OEM specifications for voltage and runtime. The pack is built with a smart control chip that manages charging, discharge and safety protections. It suits owners of the listed models who need a direct drop-in power source.

Upgrading from a depleted or swollen original pack

When the factory battery no longer holds a charge or shows physical swelling, this replacement restores full mobile runtime. The jump is worth it if your laptop shuts down unexpectedly or runs only on AC power. It also replaces part numbers PA3816U-1BAS, PA3816U-1BRS, PA3817U-1BAS, PA3817U-1BRS, PA3818U-1BRS and PA3819U-1BRS. Buyers who need a higher capacity than 4400 mAh or a different voltage should look elsewhere.

Straightforward installation with model verification

The battery slots into the existing bay without tools; alignment tabs guide it into place. Before fitting, compare the shape, connector orientation and part number with your original unit to avoid mismatches. The most common issue is ordering the wrong variant for a similar-looking Satellite chassis. The smart chip handles charge calibration automatically after the first full cycle.
