SKU CH-538D-E4E7W

Replacement 10.65V 58Wh lithium-ion battery for Panasonic Toughbook CF-19 MK1-MK8 series

  • 65V 58Wh capacity powers extended field work
  • Li-ion 3-cell design delivers stable current output

  • Replaces CF-VZSU28 CF-VZSU48 CF-VZSU50 part numbers

Panasonic Toughbook CF-19 replacement battery

This 10.65V lithium-ion pack delivers 58Wh of capacity across three cells. It is built for users whose CF-19 series laptop no longer holds a charge or fails to power on. The battery matches the original CF-VZSU48 form factor and voltage. It restores mobile runtime to rugged devices used in field service, logistics or public safety roles.

Upgrade from degraded or failed original cells

The unit replaces part numbers CF-VZSU28, CF-VZSU48, CF-VZSU48U, CF-VZSU48R, CF-VZSU50 and CF-VZSU58U across MK1 through MK8 revisions. The jump is worth it when the original pack drops below usable runtime, swells or triggers shutdowns under load. Fresh grade-A cells and a new protection circuit restore the factory 5700mAh rating. UL, CE, FCC and RoHS certifications confirm the safety baseline.

Suits owners of any CF-19 MK1 to MK8 needing

Buyers who want more storage, a different voltage or a higher cell count should look elsewhere. The pack fits only the listed Toughbook models and the specified part numbers. It is not a universal laptop battery and will not fit other Panasonic series or third-party chassis. Confirm the original part number on the label before ordering.

Questions about this item

How do I confirm the CF-VZSU48 battery will fit my Toughbook CF-19 MK6?

Open the back cover and match the original battery model number and appearance to the CF-VZSU48, CF-VZSU28, CF-VZSU48U, CF-VZSU48R, CF-VZSU50 or CF-VZSU58U part numbers listed for this replacement.

What is the correct installation step that users often miss when replacing the CF-VZSU48 battery?

Before fitting the new 3-cell lithium-ion pack, verify the original battery model and compare its physical layout to the replacement to ensure the connector and screw holes align correctly.

When will the 58Wh 5700mAh CF-VZSU48 battery need replacement?

Replace the battery when the Toughbook CF-19 no longer holds a charge, shuts down unexpectedly, or shows significantly reduced run time compared to the rated 58 watt-hour capacity.
