Greetings MacRumors POWER PC FANS! Sadly due to my location being in Canada I can't get new PRAM batteries for my macs... I tried OWC And they wanted $27 shipping, Amazing they wanted $20 shipping and my local "the source" store wanted $21 + tax and this was their "Clearance" price. And since I'm really short on cash and wanted to get my macs to hold time i decided to make my own. My first post i showed the tangerine G3 that i have below with 2 Double A's adding up to 3Volts and it held time. Sadly though The holders to these batteries where a little big and i placed them under the DVD rom drives. But it was really tight and i did not like the way it was seated under there! So when i was at work i found a new Motherboards at the back of the shop and though, the CMOS batteries for PC's are 3Volts too. I grabbed a few boards un soldered the Battery holders for the 3 Volt batteries grabbed a few used batteries that all had 3v and took them soldered some power button cables to them and then to the imacs. I then used a hot glue gun to glue the bottom of the battery holder to avoid a short circuit. So i put a layer of glue there to prevent that and then after it dried i put another layer and as shown below glued it to the CD-Rom/Hard drive caddy. Now i have both G3's holding time by Beige G3 is next along with my EMac. It looks good and clean i can easily replace the battery if needed and it holds on. What do you guys think? EDIT: the first photo Left is my G3 before i put the new button battery in. the right is the Indigo Imac with the finished product. Sadly i didnt photograph the same machine. The bottom is the motherboard that i got the holder from.
