Been a while, but seems every 7 to 10 years, I need a new Nicd for my Makita cordless 9.6V. I think I bought it in 1988, got a few more years on the battery. It has served me very well, thank you. Although I like the new cordless with the LED lights built in so you can see what you are working on. Now if I could just find my damn reading glasses that fell off my nose while working.
