The backup battery (supercap?) is welded to its bracket and won't push out.
I replaced the backup batteries in my GTA02s with supercaps several years ago. http://www.jeepingben.net/zen/zenphoto/index.php?album=2010/freerunner_supercap_install The parts I used didn't match the original footprint so it was a little work. If you get the exact replacement part, it would be easy if you have soldering experience. I vaguely remember a software problem causing the line that charges the backup bat/cap not being set high.
