Replacement battery for Toshiba Satellite C855 L855

This 6-cell 10.8V 48Wh lithium-ion pack replaces original Toshiba part numbers PA5024U-1BRS, PA5023U-1BRS, PA5025U-1BRS and PA5109U-1BRS. It fits Satellite C55, C855, L855, L875, P855, P875, S855 and S875 series notebooks as well as Qosmio T752 models. Buyers needing a higher-capacity 9-cell unit or a battery for ultrabook chassis not listed here will not be served by this item.

No bundled accessories or software included

The package contains only the battery itself; no screwdrivers, installation guides or diagnostic utilities are supplied. Users must reuse the original retention screws and latch mechanisms from the old pack. The absence of a calibration tool means the operating system must relearn the charge curve through normal charge-discharge cycles.

Straightforward swap with a known recognition quirk

Installation requires releasing the latch, sliding out the old pack and inserting the new one until it clicks. If the system fails to recognise the battery or stops charging early, the supplier recommends a nine-step power-cycle routine: shut down, remove AC, remove battery, apply AC, boot to OS, shut down normally, remove AC, refit battery, then boot again. This clears the embedded-controller cache on most affected machines.

Questions about this item

How often will the 6-cell 48Wh battery need to be replaced under normal use?

A 6-cell 48Wh lithium-ion pack typically lasts several hundred full charge cycles before capacity drops below 80 percent, so replacement timing depends on how often you discharge and recharge it.

What is the first limit reached when the PA5024U-1BRS replacement runs continuously on a Toshiba Satellite C855?

The 4200 mAh capacity determines runtime; once the cells deplete, the battery management circuit cuts power to protect the pack, so usable time is the primary limit.

Does the 10.8V 48Wh pack get hot or noisy during all-day operation on a Satellite L855?

The battery has no moving parts and runs silently; it warms slightly under load but stays within normal lithium-ion temperature limits for a 6-cell design.
