Panasonic CF-33 Extended Battery

The Panasonic CF-VZSU1BW is a genuine extended battery designed specifically for the CF-33 rugged tablet. It supplies the main power cell only, without a battery cover or bump-out cover included. This unit aims to extend backup time up to three times compared to the standard battery. It suits mobile professionals needing longer untethered operation.

Field workers needing maximum runtime

Users who require the protective bump-out cover or the standard battery cover must source those parts separately, as they are not supplied with this item. It is not suitable for buyers expecting a complete drop-in module with enclosure pieces included. Anyone needing a standard-capacity battery should look at the regular CF-33 battery option instead.

Extended capacity for CF-33

The extended cell comfortably handles full work shifts away from mains power, roughly tripling the standard runtime for typical workloads. It runs out when the stored charge depletes after prolonged heavy use or multiple days without recharging. Actual endurance varies with screen brightness, wireless activity and processing load on the CF-33 tablet.
