I agree. I just had to dismantle the whole frame of a Belkin F6C-100 to get
some 4 year old batteries out of it. They hadn't leaked enough to hurt
anything, but they were swelled up as if they were wet batteries at -60F and
wedged into place quite snuggly. It had died a year ago, and I decided I
could afford $80 for a set of new ones since I wasn't able to see any
overheated/smoked parts, just a stiff cooling fan that probably baked them to
a quite well done state.
