Dr. Battery MPL16204P-05 6-cell 4400 mAh 10.8 V laptop battery

Replacement battery for Toshiba Satellite laptops

This Dr. Battery MPL16204P-05 is a new 6-cell lithium-ion pack rated at 10.8 V and 4400 mAh. It fits a wide range of Satellite A and L series models including the A200, A300, A350, A500, L300, L450, L500 and L550 families. The black casing matches the original aesthetic and the 48 Wh capacity targets the same runtime envelope as the factory unit. Buyers who need a higher-capacity pack or a different voltage will not be served by this model.

Upgrading from a depleted or failing OEM pack

The unit replaces original part numbers such as PA3533, PA3533U, PA3533U-1BAS, B-5038 and K000046320. It is worth fitting when the old battery no longer holds a useful charge, shows swelling or triggers a replacement warning in the operating system. The jump restores the original 10.8 V specification and the built-in smart control chip manages charging and discharge within OEM limits. Users whose laptop requires a different cell count or voltage should not use this pack.

Straightforward swap with built-in safeguards

Installation consists of releasing the battery latch, removing the old pack and snapping this one into the same bay — no tools or firmware updates are required. The integrated protection circuit guards against short circuit, overheat and overload during the first charge cycles and thereafter. The most common issue is ordering the wrong variant; verify the laptop model and original battery part number against the compatibility list before purchase.
