I have a Powerbook 540c battery I'd like to get restored. I actually used to have 2 of the batteries but I made my own attempt at rebuilding one and it went... poorly. So I'd like to send the remaining one out. There used to be a couple of services doing it but their websites are out of date by ~10 years, no replies, most recent reviews are from years ago, etc. Has anybody had a battery rebuilt in the last couple of years that can make a current recommendation?
