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

This 4-cell lithium-ion pack delivers 10.65V and 8.55Ah of capacity. It replaces Panasonic part numbers CF-VZSU46, CF-VZSU46S, CF-VZSU46U, CF-VZSU46R, CF-VZSU71U, CF-VZSU72U and CF-VZSU1430U. The unit is new and carries UL certification. It is built for field-service professionals who need a direct swap for the original battery.

Practical limits of the 4-cell lithium-ion design

A four-cell configuration provides a fixed energy ceiling of 8.55Ah at 10.65V. Run-time will vary with screen brightness, wireless radios and workload intensity. The pack fits only the listed Toughbook models; it cannot be used in other laptops or charged by non-Panasonic adapters. Capacity will degrade gradually over charge cycles.

Check your existing battery before ordering

Remove the current pack and confirm the part number matches one of the compatible codes above. Verify that the voltage printed on the label reads 10.65V. Ensure the battery bay and latch mechanism are undamaged so the replacement seats securely. This product is not suitable for users needing higher capacity or a different form factor.

Questions about this item

Should I choose the 8.55Ah version or a different capacity for my Toughbook?

This battery is supplied at 8.55Ah and 10.65V; select it when your original part number matches CF-VZSU46, CF-VZSU46S, CF-VZSU46U, CF-VZSU46R, CF-VZSU71U, CF-VZSU72U or CF-VZSU1430U.

What does the 10.65V rating mean once the battery is installed in a CF-30, CF-31 or CF-53?

The 10.65V output matches the voltage required by those Toughbook models, so the system will recognise the pack and charge it normally.

Which interface does the pack use and what does it limit in practice?

The pack connects through the proprietary Toughbook battery bay used by the CF-30, CF-31 and CF-53 series; it fits only those chassis.
