A 14.8 V 2200 mAh 4-cell lithium-ion battery compatible with listed Toshiba Satellite models

  • Battery TypeLithium-Ion
  • Lithium-ion chemistry delivers stable power for daily tasks
  • 2200 mAh capacity extends runtime between charges

  • Certified to CE and RoHS for safety compliance
  • Compatible with Satellite C55 and S55t models listed

14.8V 4-Cell Lithium-Ion Replacement

This 14.8V lithium-ion battery replaces the original pack in compatible Toshiba Satellite models. It delivers a 2200mAh capacity across four premium cells and is certified by CE and RoHS for safety. The unit is built to meet or exceed the original manufacturer specifications and carries a one-year replacement warranty.

Upgrade from worn or failed original packs

Swap this battery in when the original no longer holds a useful charge or shows reduced runtime. The 14.8V rating also fits devices specified for 14.4V, so the jump is worth it whenever the existing pack is depleted, swollen or simply aged beyond reliable daily use.

2200mAh capacity for everyday workloads

The 2200mAh rating comfortably powers typical office tasks, web browsing and media playback on supported Satellite C55 and S55t units. Runtime will taper under sustained heavy loads such as continuous video rendering or gaming sessions where the draw exceeds the cell headroom.
