Direct replacement for Satellite C55 C55D C55T L55

This 4-cell lithium-ion battery delivers 33 Wh at 14.8 V and is compatible with 14.4 V and 14.6 V systems. It replaces part numbers PA5184U-1BRS PA5185U-1BRS PA5186U-1BRS PA5195U-1BRS across the listed Satellite series. Buyers who need a higher-capacity pack or a different form factor cannot use this unit.

Steady output during extended sessions

The 2200 mAh cell configuration maintains consistent voltage under continuous load rather than only in short bursts. Lithium-ion chemistry supports stable discharge throughout the usable capacity range. Users who require hot-swap capability or an external charging dock will not find those features here.

Slim profile fits original bay without modification

The pack matches the factory dimensions for the C55 C55D C55T L55 L55D L55T chassis so the latch engages securely. Connectors align with the motherboard header exactly as the original equipment did. No tools or adapter cables are needed for installation.

Questions about this item

Does the 14.8 V lithium-ion pack run hot or draw extra power during all-day use?

The 33 Wh, 4-cell lithium-ion battery operates at the standard 14.8 V (also compatible with 14.4 V and 14.6 V systems) and does not increase heat or power draw beyond normal laptop charging behaviour.

Must my Toshiba Satellite already have a working PA5185U-1BRS or PA5184U-1BRS battery installed for this replacement to fit?

No, this 4-cell pack is a direct replacement for part numbers PA5184U-1BRS, PA5185U-1BRS, PA5186U-1BRS and PA5195U-1BRS and fits the listed C50, C55, C55D, C55T, L55, L55D and L55T models without any other components.

Will the 2200 mAh capacity work properly in an older Satellite C55-B5200 that originally shipped with a 4-cell battery?

Yes, the 33 Wh, 2200 mAh capacity matches the original 4-cell specification for models such as the C55-B5200, C55-B5270 and C55D-B5310, so runtime and charging behave the same as the factory pack.
