Replacement Battery for Portege Z30 Series

This lithium-polymer pack replaces the original PA5136U-1BRS unit in Toshiba Portege Z30, Z30-A and Z30-A1301 laptops. It delivers 14.8 V and 3380 mAh (52 Wh) from four Grade A cells. The pack is 100 % new from the manufacturer and carries CE, FCC and RoHS certifications.

Capacity and Cycle Life

The 52 Wh rating provides a full day of typical office work before a recharge is needed. Rated for 500-plus recharge cycles, the battery maintains usable capacity well beyond the first year of daily charging. Runtime will fall off sooner under heavy multi-tasking or high screen brightness.

Voltage Match Requirement

The 14.8 V output must match the voltage printed on your original battery; a different voltage will prevent the laptop from powering on. Verify the part number PA5136U-1BRS before ordering.

Questions about this item

Will this 14.8V 3380mAh pack fit alongside the original charger in my Portege Z30-A1301?

Yes, it matches the PA5136U-1BRS part number used by the Portege Z30, Z30-A and Z30-A1301 series, so the existing AC adapter charges it normally.

How can I verify the battery is working correctly after I install it?

The operating system should report a 4-cell lithium-polymer pack at 14.8V and roughly 52Wh, and you should see normal charge and discharge cycles without error messages.

What comes in the box and is any extra cable or tool required?

Only the battery pack itself is supplied; no additional cables, screws or tools are included, and none are needed for the standard internal swap.
