Buyers whose laptop requires a different voltage, cell count or physical connector will not be served by this pack. It is not for users who need a higher capacity than 48Wh or a form factor that differs from the original PA3832U-1BRS series.

4400mAh capacity handles typical office workloads

Runtime shortens under sustained heavy loads such as video rendering or gaming. The 48Wh rating provides a baseline for comparing against your original battery's stated capacity.

Questions about this item

Which laptop models accept the 10.8V 4400mAh battery with part number PA3832U-1BRS?

This 6-cell lithium-ion pack replaces the original PA3832U-1BRS, PA3833U-1BRS, PA3929U-1BRS, PA3930U-1BRS and PA5043U-1BRS batteries in Portege R700, R705, R830, R835, R930, R935, Satellite R630, R830, R835, R845, Tecra R840, R940 and Dynabook R730, R731, R732, R741, R742, RX3 models.

Will the smart control chip manage charge cycles on a Tecra R940 that originally used a PABAS249 battery?

Yes, the built-in chip provides quicker charging, lower power consumption, longer discharge time and short-circuit, overheat and overload protection for the PABAS249-compatible Tecra R940.

How can I confirm the 48Wh pack is delivering its rated capacity after installation?

Charge the battery fully, then run the laptop on battery power until shutdown; the runtime should match the 4400mAh / 48Wh rating for your workload.
