I used to use them for refilling batteries for my Thinkpad 600's. I probably did 3 or 4 batteries. Generally, I thought they were pretty good as long as you didn't care too much about perfect aesthetics of parts of your machine that are generally hidden from view. In my case, the refilled batteries lasted as long or longer than original IBM batteries, and they were definitely higher capacity and so initially had a longer battery life too. I never had issues with batteries fitting in the slots after being refilled, but once I had a problem where the casing started to come apart where they had glued it. Once, they also took one battery back and replaced it when I ran into a problem. My experience dates to 4-5 years ago, however, and I recall that there were issues with some people getting prompt responses/mailings from them following that. I am not sure if those issues were resolved in subsequent years.
In the case of a 600X with a SpeedStep PIII 650+ CPU, refilling an original IBM battery is required instead of using a generic replacement if you want to get a properly working SpeedStep system under Windows -- the original IBM circuitry is somehow necessary to achieve max speed. I have not heard of this specific SpeedStep quirk affecting any other Thinkpads.
