Replacement Battery for Chromebook CB30 and CB35

This 45Wh lithium-ion cell delivers 10.8V and 3860mAh to restore original run-time on compatible Toshiba Chromebooks. It matches the PA5208U form factor so installation requires no modification. The pack arrives new and ready for an initial conditioning cycle.

Suitable for owners of CB30 CB35 CB35-B3330

Users needing a higher capacity than 45Wh or a different voltage should look elsewhere. The battery is not designed for laptops outside the listed Chromebook series. Buyers who cannot verify their original part number against PA5208U should confirm compatibility before purchase.

45Wh capacity at 10.8V

The 45Wh rating determines whether this pack meets the runtime requirement for the target Chromebooks. A lower or higher watt-hour value would indicate a different part. Matching this figure to the original battery label confirms the correct replacement.
