A quick video of me repairing a pair of Snap-On digital calipers. I received them as a gift a few years ago but the cover for the battery broke and I lost it shortly after. I decided to use two AAA batteries as a replacement instead of fixing the existing case and having to buy another special button cell battery which would be much more expensive. The previous battery should've allowed the tool to work for like 10+ years so this upgrade should last me for as long as the calipers function accurately.
