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.
