45Wh replacement for Toshiba Satellite

This 45Wh lithium-ion battery replaces the PA5185U-1BRS pack in compatible Toshiba Satellite C50, C55, L55, S40 and S55 series notebooks. It delivers 14.4V nominal voltage and works with systems that specify 14.8V, providing a direct drop-in power source for ageing or failed original cells.

2800mAh capacity and cycle headroom

The 2800mAh rating supplies typical office and web workloads for several hours on a full charge, while the rated 600-plus charge cycles give multi-year service before capacity drops below useful levels. Heavy continuous loads or high screen brightness will reduce single-charge runtime, and cells will eventually degrade past the point of holding a full day’s work.

Bundled screwdrivers and protection circuits

Two screwdrivers and a fitting guide let you swap the pack without sourcing tools separately. Built-in overcharge, overdischarge, over-temperature and short-circuit protection guards both the battery and the laptop during daily use and extended storage.
