Compatible Toshiba Satellite battery

This 6-cell lithium-ion battery replaces the PA3817U-1BRS pack used across many Toshiba Satellite L and C series laptops. It delivers 58 Wh and 5200 mAh capacity for extended mobile use. The unit is brand new and matches the original form factor for direct installation.

Simple slide-in installation

The battery seats into the standard bottom bay without tools or cable routing. Most users complete the swap in under a minute by releasing the latch and sliding the pack home. A common mistake is forgetting to fully engage the locking tabs, which leaves the pack loose and prevents charging.

For owners of listed Satellite models

This pack suits owners of the compatible Satellite L, C, P and M series notebooks who need a fresh 6-cell replacement. Buyers whose laptop requires a 9-cell or higher-capacity pack should look at something else.

Questions about this item

How can I confirm the 58 Wh battery is charging correctly after installing it in my Toshiba L755?

The laptop's battery indicator should show charging progress and the OS will report the design capacity near 58 Wh once the new pack is recognised.

What comes in the box and do I need any extra parts to fit the PA3817U-1BRS into a Satellite C655?

The package contains the 6-cell 5200 mAh lithium-ion battery only; no tools or cables are required as it slots directly into the existing battery bay.

Which part number should I choose if my original battery is labelled PA3818U?

This unit replaces PA3817U-1BAS, PA3818U, PA3819U and PA3816U-1BRS, so it matches the PA3818U label directly.
