Compatible Toshiba Portege Z30 models

This Cameron Sino replacement battery fits a wide range of Toshiba Portege Z30 and Z30-A ultrabooks. It matches the original PA5136U-1BRS and S02M part numbers. The lithium-polymer cell delivers 3.35 Ah capacity in a black housing. It restores mobile power for daily productivity.

Upgrading from a depleted original pack

When the factory battery no longer holds a useful charge, this unit restores full runtime without modifying the laptop. The swap is worthwhile once the original cell drops below half its initial capacity or shows swelling. No firmware update or hardware change is required for the replacement.

Check your exact model number before ordering

Verify that your device appears in the supported list such as Portege Z30-A-1CX, Z30-A-18J or Z30-B variants. Confirm the original battery label reads PA5136U-1BRS or S02M for a direct fit. Ensure the laptop chassis accepts the same physical dimensions as the original pack.
