Compatible Battery for Toshiba Portege R30 Series

This replacement battery fits Toshiba Portege R30 and R30-A series laptops. It matches original part numbers PA5161U-1BRS, PA5162U-1BRS, PA5163U-1BRS and PA5174U-1BRS. The 10.8V 4400 mAh Li-ion cell restores mobile power for business and everyday productivity use.

Fits Directly Into the Existing Battery Bay

The pack slides into the laptop without adapters or cable changes. Built-in protection guards against over-charge, over-discharge, overheating and short-circuit. OEM-grade cells deliver stable output and long cycle life so the system runs reliably on battery alone.

Replaces Worn or Failing Original Packs

Swapping the old unit restores full runtime when the original no longer holds charge. The upgrade is worth it when the laptop shuts down early, reports reduced capacity or the battery physically swells. Buyers needing higher capacity than 4400 mAh or a different voltage should look elsewhere.
