Dr. Battery MPL16204P-30 6-cell 10.8V 4400mAh laptop battery

Dr. Battery 6-Cell Replacement

The Dr. Battery MPL16204P-30 is a new 6-cell lithium-ion pack rated at 10.8V and 4400 mAh. It replaces original Toshiba batteries including the PA3533U-1BRS and PA3534U-1BAS series. The unit fits a wide range of Satellite A and L series notebooks from the 200 through 555 model families. A built-in smart control chip manages charging and provides short-circuit, overheat and overload protection.

Voltage and Capacity Limits

The battery delivers a fixed 10.8V output and 48 Wh of energy storage. Runtime scales directly with the notebook's power draw, so heavier workloads will deplete the 4400 mAh capacity faster than light use. The lithium-ion chemistry requires operation within standard temperature ranges to maintain the rated cycle life. No higher-capacity or alternative-voltage version is offered in this model.

Upgrading from Depleted Packs

This pack restores mobility to Satellite laptops whose original cells no longer hold a useful charge. The jump is worth it when the existing battery reports significantly reduced capacity or triggers early low-power warnings. It does not add new features or increase the system's maximum performance envelope. Buyers needing extended runtime beyond 48 Wh or a different form factor should verify compatibility before ordering.
