I am looking for a PRAM battery for my Powerbook G4 500 mhz. I saw on at We Love Macs http://www.welovemacs.com/9224361.html

Its $90 but looks like it is just $15 worth of hearing aid batteries soldered together. Is there a do it yourself or cheaper alternative?

It's listed as 'out of stock' but the price is $39.95. Check out the other usual suspects for Mac parts: pbparts.com, cdw.com, smalldog.com, etc. You'll find something for less than $90, I think.

I saw the ifixit price. They don't intend to have any soon. Ebay has nothing. pbparts wanted $69 plus shipping. Small Dog, CDW, MacZone don't have the vintage parts. Strange that some of these guys stock the G3 powerbook PRAM batteries for less than $20.

Are they special gold-filled batteries or can I get them at Longs Drugs?

AFAIK, they are more-or-less standard coin cells....but! You'd have to solder to them, and soldering to Ni-chemistry coin cell batteries is quite difficult. Welding tabs on is, IIRC, preferred, but most folks don't have the equipment to weld stuff like that. Of course, if they're rechargeable Li-chemistry coin-cells, you should stay far away from them with a soldering iron. That's just begging to get yourself hurt.

Unless you're a good hand with a soldering iron and you've got a good iron as well, you are likely going to come out ahead paying for them. If you're tempted to build up something yourself, make sure you know what you're working with, and practice on the old/dead batteries first.

I just read an article in Wired about how volatile these batteries are. It didn't occur to me I was going to attempt to disturb the chemistry. Stupid me.

Thank you for the warning.

I check their website and then called the local Burbank store (818) 526-8100, They do not stock them. Do you know something I don't?

The part number is 616-0114-A Please provide me with a phone and/or link for this $6 solution. Thank you very much for the money saving tip.
