Rectangular black lithium-ion laptop battery with four cells and label showing 14.8V 2200mAh

Toshiba

Toshiba Satellite C55/C55D 14.8V 2200mAh 4-Cell Laptop Battery

SKU CH-K9RR-223MR

14.8V 2200mAh 4-cell lithium-ion replacement battery for Toshiba Satellite C55 and C55D models

  • Battery TypeLithium-Ion
  • Reliable lithium-ion chemistry powers work and play
  • 2200 mAh capacity extends runtime between charges
  • Four premium cells deliver stable 14.8 V or 14.4 V output
  • CE and RoHS certified for safety and environmental compliance
  • One-year replacement warranty backs long-term durability

Compatible Satellite Models

This 14.8V lithium-ion battery fits Toshiba Satellite C55 and C55D series laptops including models 5242, 5244, 5308, 5287 and 5290. It replaces the original PA5185U-1BRS pack and supplies 2200mAh across four premium cells. Buyers needing a different voltage or a higher capacity pack should look elsewhere.

Upgrade From Worn Originals

The jump is worth it when the factory battery no longer holds a useful charge or shuts down under load. A fresh 4-cell pack restores the runtime the notebook had when new and is certified by CE and RoHS for safety. It will not add capacity beyond the original 2200mAh specification.

Simple Swap Installation

Installation requires only releasing the latch and sliding the new pack into the same bay; no tools or software steps are needed. The battery is built to meet or exceed the original manufacturer specifications for fit. The only common issue is forgetting to fully charge the new pack before first use.

Questions about this item

Will this 14.8V 2200mAh 4-cell battery fit my Satellite C55-B5287 chassis?

Yes — the pack is listed as compatible with the C55-B5287, C55-B5290, C55D-B5242, C55D-B5244 and C55D-B5308 models.

What is the correct way to insert the battery so the latch engages?

Slide the pack into the bay until the release latch clicks; forcing it before the click leaves the contacts misaligned.

When should I replace this lithium-ion pack?

Replace it when run-time drops far below the original 2200 mAh capacity or the pack no longer holds a full charge.
