14.8 V 2200 mAh replacement battery

This 14.8 V lithium-ion pack supplies 2200 mAh across four premium cells. It is built as a direct replacement for compatible Toshiba Satellite models and matches the original manufacturer specifications. CE and RoHS certification confirms safety and stability standards are met. The unit is supplied new with a full one-year replacement warranty.

Fits Satellite C55D C55Dt S50-C series

The battery suits owners of Satellite C55D-C5271, C55Dt-B5128, C55Dt-B5208, C55Dt-B5296, S50-CBT2G01, S50-CST2GX1 or C55t-B5109 machines needing a drop-in swap. It also works with devices rated for 14.4 V operation. Buyers whose laptop requires a different voltage or cell count should look elsewhere. Laptops outside the listed model range are not supported.

2200 mAh capacity for daily workloads

The 2200 mAh rating delivers enough energy for typical office tasks, web browsing and media playback on supported hardware. Runtime scales with screen brightness, processor load and peripheral use. Heavy workloads such as sustained gaming or video rendering will deplete the charge faster. The pack does not increase the original design capacity beyond 2200 mAh.
