I have a cabinet shop and most all my machines use digital read-outs that take 2 AA batteries. These readouts can go through as many as 5 sets a year and seeing that I have 7 of these, that is a lot of batteries. I was going to start getting recharable batteries and wondered if betweent the 2 or 3 brands out there if there was really a difference? I wanted to ask before I go down to my local big box store and buy what seemed like a good deal. The only thing I know about modern rechargable batteries is that my makita nickle metal hydride batteries were far better than my dewalt lithium ion batteries and there is newer technology out there with whick I am not familiar. Thanks folks, I know this seems like a small thing, but every dollar I can save is worth it.
