Replacement battery for Toshiba Satellite

This new 6-cell lithium polymer battery replaces the PA3817U-1BRS unit in compatible Toshiba Satellite notebooks. It delivers 10.8V output and 5200mAh capacity rated at 58Wh. The black casing matches the original form factor and includes an instruction manual.

Voltage and capacity match

The single specification that decides fit is the 10.8V 5200mAh rating; systems requiring a different voltage or cell count will not work with this unit. Compatible part numbers include PA3816U-1BRS, PA3817U-1BAS, PA3818U-1BRS, PA3819U-1BRS and the PABAS227 through PABAS230 series.

Questions about this item

What does the 58Wh rating actually deliver in a typical Toshiba Satellite notebook?

The 58Wh capacity is designed to match the original battery's energy rating, giving comparable run time on compatible Satellite models when fully charged.

How does the 10.8V output work with the laptop's 19V AC adapter?

The battery supplies 10.8V directly to the system; the 19V adapter connects to the laptop's charging circuit, which manages voltage conversion and battery charging independently.

Will the 9.06 x 1.89 x 0.79 inch case fit my Satellite's battery bay without modification?

The dimensions match the standard PA3817U form factor used across the listed Satellite series, so it seats in the existing bay using the original latch mechanism.
