Yes, OWC stocks the PRAM battery
. Radio Shack used to stock the PRAM battery, although it was listed for nearly $20 the last time I saw one there, so I haven't been back (might still be in stock, might be a different price).
Hmm. Looks like Amazon has some too
. You can even get overcharged for the OWC battery
! I wonder if they just place an order with OWC and ship the order to you when you place an order with them?
As for instructions... it's really easy
. There's usually a plastic clip that goes over the battery that is easy to tug off, then you just flip flop batteries and reinstall the clip. As shown in the instructions, some of the systems don't even have a clip.
@MB: Appreciate the links . . . be a couple of days before I'll have the time to pull the computer out from behind the MacPro . . . . Most of it is straightforward, but, as far as the battery in the G4 goes, the last time I had to pull the battery out to regain control of the computer after the new eBay cpu took over the system and trashed all of the installs, when I tried to remove the "clip" it broke . . . so there must have been something more to it than simply flexing the holder as it usually is popping batteries in and out . . . it was "more complicated" . . . . The battery seemed to be stable after I put it back in . . . prolly wouldn't stay in if I turned the computer up-side-down . . . .
Back to it here when I figure out if anything changes . . . seems like you are saying that Amazon has the best prices for PowerMac G4 PRAM batteries??
Edit: Looks like OWC sales has the battery available for less than Amazon, and a couple posts on the Amazon page show complaints of short life and/or Chinese knockoffs being sent out . . . And, of course the OWC page shows all of the compatible machines and that does include the PM 3,3--it also says that on some older machines the screen "may go black to indicate a dead battery" . . . although it doesn't say that other items like the op drive also stop working . . . since the battery is long overdue for lifespan I could just order it before bothering to mess with anything . . . we'll see. The only other possibility is if the rambunctious young cat we have decided to wedge himself between the back of the PM and an old printer . . . then ***maybe*** the video cable was tweaked . . . but, power cord is still working???
