The replacement battery and the original lasted about three months each. Not happy. I read a lot, I was under the impression the first time was a fluke, guess not. And since they are back ordered I am SOL but so is Amazon but they will now lose an easy $50 or more from me ordering every month plus I had planned to buy one each for my son and daughter for Christmas. I like Amazon but I want quality and when I want to order I want it available. Suggestion, for those that go through a lot make an offer of automatic shipments of battery at a discount or make the battery last longer.
