The purpose of this article is to list the battery contacts for the Fluke-374 FC, Fluke-375 FC, Fluke-376 FC. The battery compartment is consisting of 1 dual battery contact part number 4386306, 1 positive battery contact part number 3665520 and 1 negative battery contact part number 3665535.
The negative is prone to failure because there's not enough space for the battery so it compresses and creates a fatigue point and it'll snap within months. Same for the 373.
