Replacement battery for Portege X30W-J

This KingSener PS0010UA1BRS battery replaces part numbers PS0010UA1BRS and 41CP5/63/69. It is built for the Toshiba Dynabook Portege X30W-J series. The unit delivers 15.4V and 53WH capacity using Li-ion cells. It arrives new with a black casing.

Suits X30W-J owners; not for X30L

This battery fits the Portege X30W-J series only. The similar PS0011UA1BRS model for the Portege X30L is not interchangeable with this unit. Buyers who need a battery for the X30L should look elsewhere. Confirm the original part number before ordering.

Voltage and capacity define fit

The electrical rating is 15.4V and 53WH, which equals 3450mAh. These figures must match the original battery exactly for safe operation. A different voltage or capacity will not work in the X30W-J. Check the label on the old pack before purchase.

Questions about this item

How long will the 53WH rating last on a typical charge?

The 53 watt-hour capacity stores enough energy for several hours of normal use; actual runtime depends on screen brightness, workload and power settings.

Yes, 15.4V is the exact voltage specified for the compatible X30W-J series models.

Will this pack fit the X30W-J chassis without modification?

It is built to the PS0010UA1BRS form factor for the X30W-J series; the separate PS0011UA1BRS variant is for the X30L and is not interchangeable.
