I recently bought a Makita 36 V (two 18's) chain saw to prune my trees. It came with four 5AHr batteries that have the fuel gage on the back. I also have some year old new type batteries with the star on them, that came with the track saw.
Almost 10 years ago I got the then new 18V LXT combo kit with drill, impact, jig saw, sawzall, and grinder. The batteries are still in use, but finally losing power.
The year old batteries, 3AHr, work fine in the old tools, but the brand new ones have a strange problem. They work fine in the drill and impact gun, but will not fit into the other tools in the kit.
I can see that a very small quarter inch square rise on one side of the old tools slide in area is blocking their fit. Obviously I can grind it down easily with a Dremel and it would work.
Nothing on packaging for the newest batteries at HD that says they should not be used in old tools. The package just says it fits 18V LXT tools.
I can't see any reason to not do this, and am thinking mine are probably Type 1 or whatever, and there probably aren't that many left out there.
1: Anyone else run into this problem?
2: Am I missing something?
3: Why would they fit two tools and not the other three?
