  • Battery TypeLithium-Ion
  • Lithium-ion chemistry delivers a reliable charge

Replacement battery for Satellite C55Dt L55 series

This 14.8V lithium-ion battery replaces the original PA5185U-1BRS pack in compatible Toshiba Satellite notebooks including the C55Dt-C5245, L55-C5384, L55D-B5364, L55D-C5227X, L55t-C5348PL, L55t-C5388 and L55W-C5352. It uses premium four-cell construction rated at 2200mAh and is certified to CE and RoHS standards. The unit is supplied new and carries a one-year replacement warranty against material defects.

Voltage window and cell limit

The pack is designed to fit devices that accept either 14.8V or 14.4V operation; it will not work in laptops that require a different voltage. Its four-cell layout fixes the maximum energy storage at 2200mAh, so run-time cannot exceed what that chemistry and cell count allow. No circuitry in the battery can increase capacity beyond the rated figure.

Typical office workloads versus heavy loads

The 2200mAh rating comfortably powers general productivity tasks such as document editing, web browsing and video streaming for several hours on a full charge. Demanding workloads like sustained gaming, rendering or compiling will deplete the cells more quickly and may require connection to mains power for uninterrupted sessions.
