Replacement battery for Toshiba Portege

This lithium-ion battery replaces the original power pack in compatible Toshiba Portege R700, R930, Dynabook R730, R731, R732, R734 and R741 series laptops. It delivers a 4.4 Ah capacity in a black housing and is supplied new from Cameron Sino. The cell chemistry matches the factory specification for Li-ion operation.

Upgrade from a depleted or ageing original pack

When the factory battery no longer holds a useful charge or shows reduced runtime, this unit restores mobile operation to the level the notebook was designed for. The change is worth it if the laptop otherwise meets your needs but is tethered to an outlet. It also replaces OEM part numbers PABAS235, PA3831U-1BRS, PA3832U-1BRS and PA3929U-1BRS.

Verify the exact model before ordering

Check the model label on the bottom of the laptop or in the BIOS to confirm it appears in the supported list such as Portege R700-100, R700-131, R930 or Dynabook R731/W2JC. Ensure the battery bay matches the physical shape of the original pack and that the connector orientation aligns. Buyers needing a higher capacity than 4.4 Ah or a different voltage should look elsewhere.

Questions about this item

Does the DS-CS-TOR730NB fit my Portege R700-100?

Yes, the supplier lists the Portege R700-100 among the compatible models for this 4.4 Ah battery.

How do I install the battery in my Dynabook R730, and what step is often missed?

Slide the pack into the bottom bay until the latch clicks, then charge fully before first use; skipping the initial full charge is the common mistake.

When will this Li-ion pack need replacing?

Runtime will gradually fall; plan a swap once it no longer holds enough charge for your daily work.
