I have an older Makita set with drill and impact driver. I use them for everything under the sun. One battery batter recently gave the flashing red green signal when I put it on the charger. Both batteries have seen pretty equal use since, when using one tool, I cycle them rather than keep charging the same one. Both tools are still in perfect condition. Makita discontinued the 3ah batteries. They make higher amp ones, but say they only work if your tool has a star on it. I'm not one to throw out two perfectly good tools.
Has anyone used knock offs for the older Makita tools with success? Are they even still available?
