I’ve had the computer for just over two months not, still in the 90 day warranty window. The battery will not stay charged more that 30 minutes. Amazon offered a refund, not an exchange. All I want is a battery. They said no. Wouldn’t refund the $60 for the battery I’m ordering from Amazon. I don’t want to go through the hassle of setting up another computer. I use it as an automotive scan tool and to load the Ford diagnostic software is a pain. I don’t understand why they can’t just give me a battery. Other than that the computer is perfect. Great value for the money.
