With regards to the original post in this thread.
FW have already admitted there was a problem that could cause 61W batteries to age and swell, and they have publicly stated that they will replace them, even outside the original 1 year warranty period.
So, if the original poster does come back, their problem is most likely to be resolved amicably.
FW support occasionally make mistakes, emails are not a reliable form of communications, but it generally works out in the end.
