Replacement Battery for Toshiba Satellite

This 11.1 V lithium-polymer pack delivers 4400 mAh and 49 Wh across six cells. It replaces part numbers PA5109U-1BRS, PABAS272, PABAS271, PABAS273, PA5110U-1BRS and PA5108U-1BRS. The unit fits a wide range of Satellite C55, C55D, C855, C875, L75, L855, L875, M840, P845, P855, P875, S70DT, S855 and S875 models. Buyers needing a different voltage or connector layout cannot use this pack.

Sustained Discharge Behaviour

Built-in overcurrent, anti-overcharge, anti-overdischarge and temperature-control circuits protect the cells during long sessions. The manufacturer rates the battery for up to 500 recharge cycles over its service life. Consistent output is maintained by the protection board rather than by raw cell chemistry alone. Users who require hot-swap capability or external charging cradles will not find those features here.

Thermals and Power Draw

Temperature monitoring prevents overheating while the pack powers the notebook under normal workloads. Low internal resistance keeps energy loss minimal during charge and discharge. No active cooling is required because the design relies on the laptop chassis for passive heat dissipation. Buyers expecting a fan-assisted module or a ruggedised enclosure for extreme environments should look elsewhere.

Questions about this item

Does the 11.1 V 4400 mAh pack run hot or make noise during all-day use?

It is a sealed Li-polymer battery with no moving parts, so it produces no audible noise and generates only normal warmth during charging or discharge.

What must my laptop already have for this 6-cell pack to fit and work?

Your Toshiba Satellite must use one of the listed part numbers — PA5109U-1BRS, PABAS271, PABAS272, PABAS273, PA5110U-1BRS or PA5108U-1BRS — and the matching battery bay.

Will this replacement behave the same as the original battery in my older Satellite C55-A?

Yes, it matches the 11.1 V 49 Wh specification and includes overcurrent, overcharge, overdischarge and temperature protection, delivering up to 500 recharge cycles.
