Query: Good tools, but the batteries are poor

I have two sets of these tools. I have used both sets for a couple of years and they work fine for the price. The drawback is that the batteries go bad after about a year and you can not find replacement batteries easily. When you do, they are around $100 each!! I have four total batteries and two of mine have gone bad (50%). Delta does not even list the tools on their web site and I have gone to many stores with battery in hand only to be disappointed that I can not find a replacement. I would recommend a tool set from a company that actually claims the tools on their site and offers replacement parts and batteries.
