Query: Don't waste your money...

These batteries are junk. I bought the driver and saw kit and the hammer drill kit. In the first year I replaced the drill/drivers three times...while under warranty. The saw worked well and the flashlight was the best part of this kit. Now it is a couple years old and the batteries are dead and at $90 each I am not replacing them. They were not used that often and I took care to cycle them throughly when charging. I bought Hitachi this time with a five year warranty. I wasted $600 on the Porter Cable junk.
