Questions about this item

How long will the 4100 mAh capacity actually run my Toshiba Satellite Radius 14 E45W?

The 4100 mAh rating at 10.8V delivers roughly 45Wh, which typically powers compatible Toshiba models for several hours of mixed use; actual runtime depends on screen brightness, workload and battery age.

Does the 10.8V output match the original PA5208U-1BRS battery specification?

Yes, the replacement is rated at 10.8V, the same voltage as the OEM PA5208U-1BRS pack, so it will charge and discharge correctly in the listed Satellite and Chromebook models.

Will the MPL16243P-12 pack fit inside my Toshiba Satellite Fusion L55W-C5320 without modification?

The battery is built to the original form factor for the listed Toshiba Satellite and Chromebook 2 series, so it slots into the existing bay using the original screws and latches.
