Replacement battery for Toshiba Satellite C50-B

This 4-cell lithium-ion unit replaces the original PA5184U-1BRS and PA5185U-1BRS packs used in Toshiba Satellite C50-B, C55-B, C55D-A, C55D-B, C55Dt-B, C55t-B, C70-C, C70D-C, E45, E45T, L50-B, L55-B and L55T-B models. It also fits Satellite Pro C50-B, C55-B and C55Dt-B systems. Buyers who need a different voltage or a higher cell count should look elsewhere.

Steady output through the workday

Rated at 14.8V and 2200mAh for 33Wh, the pack delivers consistent voltage under continuous load rather than spiking for a short burst. The integrated smart control chip manages charging current to reduce heat buildup during extended sessions. Overheat, short-circuit and overload protections engage automatically when thresholds are exceeded.

Slim black casing with OEM mounting

The black housing matches the original form factor and clips into the battery bay without adapters or tools. Four lithium-ion cells are arranged to keep the profile thin enough for the Satellite chassis. One-year warranty covers defects in materials and workmanship.

Questions about this item

Does the 4-cell 14.8 V lithium-ion pack run hot or draw extra power during all-day use?

The 33 Wh battery uses a smart control chip that manages charging and discharge to limit heat and power draw during continuous operation.

What must I already own to install the MPL16237P-21 in my laptop?

You need a compatible Toshiba Satellite or Satellite Pro model such as the C50-B, C55-B, L55T-B or C70-C and the original battery compartment.

Will this 2200 mAh replacement work alongside the original AC adapter I kept from my older Satellite?

Yes, the 14.8 V output matches the original PA5184U-1BRS and PA5185U-1BRS specifications so the existing adapter charges it normally.
