Replacement battery for Toughbook CF-30 CF-31 CF-53

The KingSener CF-VZSU71U is a 69WH 10.8V lithium-ion battery built for Panasonic Toughbook models CF-30, CF-31 and CF-53. It matches the original dimensions and connector layout so installation requires no modification. The pack uses cells rated for stable capacity and longer running time in demanding environments. It arrives new and ready for initial conditioning cycles.

Replaces CF-VZSU46 series

This unit substitutes the CF-VZSU46 family including CF-VZSU46S CF-VZSU46U CF-VZSU46R and CF-VZSU46AU plus part numbers CF-VZSU72U and CF-VZSU1430U. The jump is worth it when the original pack no longer holds a full charge or runtime has dropped below usable levels. A fresh 6750mAh cell restores the mobile work window without changing the laptop chassis or power adapter.

Suits field workers needing reliable mobile power

The battery suits professionals who rely on Toughbook CF-30 CF-31 or CF-53 units away from mains power and want a direct-fit replacement with no false capacity claims. It is not for users of other Panasonic models or other brands because the connector and form factor are specific to the listed series. Buyers who need a higher capacity than 69WH or a different voltage should look at other solutions.
