Replacement for Panasonic Toughbook CF-19 Series

This lithium-ion battery replaces the CF-VZSU48 family of packs used in Panasonic Toughbook CF-19 models across the MK1 to MK8 range. It delivers a rated capacity of 5.7Ah at 10.65V from six cells manufactured in Japan. The black pack is supplied new and matches the original part dimensions.

Fit and capacity limits

It suits owners of a compatible Toughbook CF-19 who need a direct drop-in replacement with the factory voltage and capacity. Buyers whose laptop requires a different part number or a higher ampere-hour rating should look at other options.

5.7Ah at 10.65V with six Japanese cells

The decisive specification is the 5.7Ah capacity at 10.65V provided by six lithium-ion cells made in Japan. This combination determines whether the pack meets the runtime and voltage requirements of the specific CF-19 unit being serviced.
