6-cell 58 Wh replacement battery

The CELUX 6-cell lithium-ion battery delivers 58 Wh and 5200 mAh for compatible Toshiba laptops. It replaces the original PA3817U-1BRS pack and fits a wide range of Satellite and Satellite Pro models listed by the supplier. The unit is supplied new and ready to install.

Who this suits and who should look elsewhere

Owners of the listed Satellite L, C, M and P series machines needing a direct swap for a worn or failed pack will find the correct connector and form factor here. Buyers whose laptop uses a different part number or requires a higher capacity cell count should verify compatibility before ordering.

Check your existing setup first

Confirm the original battery label shows PA3817U-1BRS or one of the cross-referenced part numbers such as PA3816U-1BRS, PA3818U or PA3819U. Ensure the laptop model appears in the extensive compatibility list provided. No tools beyond a standard screwdriver are typically required for the swap.
