Questions about this item

How long will the 48 Wh capacity run a typical Toshiba Satellite C850 under mixed use?

The 48 Wh / 4200 mAh rating at 10.8 V supplies roughly 48 watt-hours of energy; actual run time depends on the laptop's power draw, screen brightness and workload.

Does this battery use the same connector and voltage as the original PA5024U-1BRS pack?

Yes — it is built to the 10.8 V specification and matches the PA5024U-1BRS form factor and connector used across the listed Satellite C and L series models.

Will the pack fit a Satellite L830 without modifying the battery bay?

The replacement is designed to the same dimensions as the original PA5024U-1BRS cell, so it seats directly in the battery bay of the L830 and other compatible models.
