Replacement battery for Latitude keyboard docks

This 7.4 V lithium-ion unit is built as a direct replacement for the original pack used in Latitude 11 5175 and 5179 keyboard docks. It ships new and carries a 12-month warranty from the supplier. The black casing matches the factory colour scheme.

Capacity and voltage match

The pack delivers 28 Wh at 7.4 V, matching the electrical specification of the original battery. That voltage and capacity combination is the single figure that determines whether the dock will charge and run correctly.

Single battery in the box

The package contains only the battery itself; no tools, cables or installation guides are included. Buyers who need screwdrivers or opening picks must source them separately.
