Why this battery

Fits Toshiba Satellite C50 and C50-B notebooks replacing PA5185U-1BRS, PA5184U-1BRS, PA5186U-1BRS, and PA5195U-1BRS packs.
14.8V 2200mAh lithium-ion cell delivers 32.56Wh — matches OEM output for full CPU and display load without voltage sag.
Connector slides in vertically with locking tab on the right side; seat fully until the tab catches and holds firm.
We ran this cell through full discharge to hibernate cutoff then uninterrupted charge to 100% — BMS settled cleanly with no fault codes.
After installation, complete one full discharge cycle to hibernate shutdown, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears false health warnings.

About this replacement

Toshiba Satellite C50 / C55 Series — 14.8V Li-ion Replacement Battery (PA5185U-1BRS)

This is a 14.8V, 2200mAh Li-ion replacement battery for the Toshiba Satellite C50, C50-B, C55D, C55T-B5110, and over 300 additional Satellite variants sharing the same power rails and connector. It replaces OEM part numbers PA5185U-1BRS, PA5184U-1BRS, PA5186U-1BRS, and PA5195U-1BRS. Capacity is 32.56Wh — identical to the original specification.

Satellite C50 and C55 platform compatibility: These models share the same 14.8V four-cell architecture, connector pinout, and BMS handshake protocol. A single cell SKU covers the full range because the battery management IC reads the same EEPROM signature across all variants in this chassis family.
Bench tested on actual hardware: We cycled this cell on a Satellite C55D unit, monitoring charge acceptance and BMS communication at each stage. The protection circuit tripped correctly at low-voltage cutoff and resumed charging without fault flags after reconnection.
Post-install calibration on the Satellite C50 chassis: After fitting this cell, run the laptop on battery until Windows forces hibernate, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the false "poor health" warning that fires after any cell swap on this platform.

BIOS reporting battery health as poor immediately after replacement

The Satellite C50 BIOS stores charge history and health data in the outgoing cell's EEPROM. When a new cell is installed, the BIOS compares the blank EEPROM state against its stored baseline and flags the battery as degraded before a single cycle has run. This is not a fault with the replacement cell — it is a calibration gap. Run one full discharge to hibernate-cutoff followed by an uninterrupted charge to 100%, and the BIOS learn cycle will write fresh baseline data to the new cell's EEPROM. After two to three full cycles, the health indicator should read normal.

Laptop shutting down at 20–30% charge shown on the gauge

This happens when the fuel gauge IC is still calibrated against the old, degraded cell's voltage curve. Under full CPU and display load, the new cell's voltage profile differs from what the IC expects, so it hits a false low-voltage floor and cuts power before the cell is actually empty. It is not a fault in the replacement battery. Force two complete discharge-to-hibernate cycles followed by full uninterrupted charges — each cycle teaches the fuel gauge IC the actual voltage cliff of the new chemistry. After calibration, the shutdowns stop and the percentage reading stabilises.
