I recently took my old Power Mac 4400 160 (Power Mac 7220 in Australia and Performa 4400/160 in North America) out of storage and tried to power it up but no joy! It was working fine before it was boxed up (For about 18 months) so Im almost certain its a battery problem. The thing is I have no idea what battery I need to replace it with. http://www.macbattery.com/index.html has a list of Macs and compatible batteries but my 4400 isnt on there Any help would be much appreciated and if you think its not a battery issue please let me know. Thanks. Alan.
