Replacement battery for Satellite S50 and C55t

This 14.8 V lithium-ion pack replaces the original PA5185U-1BRS unit in Toshiba Satellite S50-CBT2N22 and C55t-B5109, C55t-B5140, C55t-B5230 models. It is built with premium four-cell construction and carries CE and RoHS certification for safety. The battery is supplied new and includes a one-year replacement warranty against defects.

Voltage match decides fit

The pack operates at 14.8 V and is also compatible with 14.4 V systems, so it will only work in laptops designed for that voltage range. Installing it in a machine that requires a different voltage will prevent the laptop from powering on or charging correctly. Buyers must confirm their original battery is rated 14.8 V or 14.4 V before purchase.

2200 mAh capacity for daily workloads

At 2200 mAh the battery delivers enough energy for typical office tasks, web browsing and media playback on a single charge. Runtime will fall short during sustained heavy loads such as video rendering or gaming, where the four-cell design reaches its limit faster than higher-capacity six- or nine-cell alternatives. Users needing all-day autonomy without a charger should consider a larger-capacity option if their chassis supports it.

Questions about this item

How long can the 2200 mAh capacity actually run a Satellite S50-CBT2N22 under normal use?

The 2200 mAh rating shows the total charge the pack stores; real-world runtime depends on screen brightness, CPU load and background tasks, so exact hours vary by workload.

Does the 14.8 V rating work with a laptop that originally shipped with a 14.4 V pack?

The pack is built to fit either 14.8 V or 14.4 V systems, so it will operate correctly in both voltage ranges.

Will the four-cell layout fit the battery bay on a C55t-B5230 without modification?

Yes, the four-cell form factor matches the original PA5185U-1BRS design, so it seats directly in the C55t-B5230 bay.
