Compatible Satellite models

This 14.8 V lithium-ion battery replaces the original pack in Satellite C55Dt-C5245, L55-C5340, L55-C5384, L55D-B5364 and L55D-C5318 notebooks. It supplies 2200 mAh capacity across four premium cells and is certified to CE and RoHS standards. The unit is designed to meet or exceed the manufacturer specifications for those specific models.

Sustained discharge behaviour

The four-cell lithium-ion construction delivers a steady 14.4 V or 14.8 V output during extended work sessions, streaming or browsing. Capacity remains stable across the discharge curve rather than dropping sharply after an initial burst. This consistency helps the laptop maintain performance without unexpected shutdowns under continuous load.

Build and connector implications

The pack uses the exact connector layout required by the listed Satellite chassis, allowing a direct swap without adapters or cable routing changes. Rigorous testing confirms mechanical fit and electrical compatibility for daily insertion and removal cycles. A one-year replacement warranty covers defects in materials or workmanship under normal use.
