In 2018 I bought a new combo set of a Sub-Compact Makita 18volt LXT cordless drill and impact driver. These units are the perfect size and balance for 95% of what I use them for. Fast forward to yesterday, 2022 and I decided to use my older, larger Makita impact driver to drive some 4 inch Timber-Loc screws and low and behold, the battery was toast and would not take a charge. Neither would the battery from its partner, the screwgun!
Moral of the story: Do not neglect your cordless tool batteries! Don't play favorites like I did, and ruin your batteries.
