Good source for coin batteries with tabs? I'm looking for a supplier of coin-type batteries, with tabs, for Powerbook units. I need them in bulk (10 to 20 units at a time), and would like to find a supplier with discount pricing for quantity. I have a stack of Powerbook and iBook models that need new PRAM batteries, including some TItanium (400-500MHz VGA models) that will not power on, which I expect is due to faulty PRAM batteries. Does anyone recall if there is a way to bypass the PRAM battery check, to turn on a Titanium with a bad PRAM battery? I recalled that Command + Shift, Option + Shift, or Control + Shift did something like this, but it has been a very long time since I was required to recall exactly what these did. Do any of you know a way to jumper the mainboard, so that the system will allow a power-on without a PRAM battery module? I hate to replace batteries in systems that I can't test at all, just to test them. I need to inspect the modules, to see if the same module is used on the VGA (400MHz and 500MHz) systems, and the DVI (800MHz to 1GHz) systems. I should have some DVI systems with no displays, from which I can rob components.
