Replacement Battery for Panasonic Toughpad FZ-G1

This NShi FZ-VZSU84U lithium polymer battery replaces the original pack in Panasonic FZ-G1 and FZ-G1AABDXER Toughpad notebooks. It delivers 10.8V and 45Wh capacity through a 4400mAh cell configuration. The part matches multiple OEM numbers including FZ-VZSU84A2K, FZ-VZSU84A2R and FZ-VZSU84AK. Verify your existing battery part number before ordering.

Sustained Runtime on a Single Charge

Under continuous load the 45Wh pack provides consistent output until the low-voltage threshold triggers shutdown. Lithium polymer chemistry maintains stable voltage across the discharge curve rather than dropping sharply after an initial burst. The 4400mAh rating reflects the total charge available when the battery is cycled properly from 100% down to the recommended 5% floor. Expect runtime to scale with screen brightness, wireless activity and processor demand.

10.8V 45Wh 4400mAh Specification Decides Fit

Voltage must match 10.8V exactly; a higher or lower rating will prevent the notebook from recognising the pack. Capacity of 45Wh and 4400mAh determines how long the Toughpad runs between charges. Connector geometry is not described in the data, so confirm physical compatibility against the original battery before purchase. Buyers needing a different voltage or capacity should look elsewhere.

Questions about this item

Does the 10.8V 45Wh lithium-polymer cell run hot or draw extra power during all-day use?

The battery is a 10.8V 45Wh lithium-polymer pack rated at 4400mAh; it supplies power to the notebook rather than drawing it, so it does not generate additional heat or noise beyond normal discharge.

What must I already have in my Panasonic Toughpad FZ-G1 for this FZ-VZSU84U pack to connect and work?

Your Toughpad FZ-G1 must use one of the listed part numbers — FZ-VZSU84U, FZ-VZSU84A2K, FZ-VZSU84A2R, FZ-VZSU84A2U, FZ-VZSU84AK, FZ-VZSU84AR, FZ-VZSU84AU, FZ-VZSU84K or FZ-VZSU84R — so the existing connector matches the replacement.

Will this 4400mAh pack charge correctly with the original AC adapter that came with my FZ-G1 series notebook?

Yes, the pack is built to the same 10.8V 45Wh specification as the original batteries it replaces, so the factory AC adapter charges it normally.
