Query: Batteries are terrible

While I like the Milwaukee product I detest these batteries. If you use them daily, like I do, you are are lucky to get 6 months out of them. I am constantly ordering new batteries becuase they simply stop charging between 5-7 mos after purchase. I have a Ryobi that I used daily before these for 6 mos and It is now 2 years old and still has the same battery. Had I known the battery stank I would not have purchased the set.
