Replacement battery for Toshiba Satellite

This 10.8V lithium-polymer battery replaces the original PA5208U-1BRS pack in Toshiba Satellite E45W, Fusion L55W-C5320, Radius 14 and 15 models plus Chromebook 2 CB35-B variants. It fits the listed machines without modification and restores mobile power for daily work or study. The black casing matches the OEM appearance.

Upgrade from a worn or swollen original pack

When the factory cell no longer holds a charge or shows physical swelling, this 4100 mAh unit restores usable runtime. The jump is worth it if the laptop otherwise meets your needs and the original battery part number matches the compatibility list. No higher-capacity alternative is offered in this form factor.

Limited to 10.8V lithium-polymer chemistry

The pack only works with devices designed for 10.8V lithium-polymer cells and the exact model numbers shown in the compatibility list. It cannot be used in laptops requiring a different voltage, chemistry or connector layout. Buyers who need a different voltage or a higher capacity must look elsewhere.
