Query: Not Happy

I bought this battery for my particular ACER laptop. The first battery that shipped wouldn't even fit and the company exchanged it. The next battery was a perfect fit and charged but I found when trying to use it that the touch pad on the PC didn't work and the computer froze. The company was slow to respond and gave me a number to call. By that time I just gave up on it. I won't go this route in buying a PC battery again.
