Which PRAM Battery for 15" Al G4 PB (A1106)?

[Droooooj]

I think my PRAM battery is dead (date resets to January 1st 1970 when started up with main battery removed) but I can't find a replacement PRAM anywhere (I'm in the UK).

According to iFixit the part number is 820-1686-A - is this the only PRAM module that will work in my machine? (I've seen lots of other similar looking parts on eBay, but with different part numbers).

Also, is it not possible to actually just replace the battery, not the whole circuitboard? It looks like a regular watch battery I could pick up for £5 from the pic.

Last I remembered, the battery is actually soldered to the metal tabs but I'm sure it's possible to just swap in a regular battery. Try removing yours to see what size battery it is. A sharp utility/razor knife should separate it.

I noticed in your last pose that you had a 1.67ghz model. Is your model the High resolution one(1440x960)? It would also have a dual-layer DVD burner and cheaper DDR2 memory.

The board you require should be on the page:

I agree that if you can unsolder original battery and find one the same that should work, replacement boards aren't cheap.(it's a U.K. site by the way)

P.S. If you leave the main battery in place it should have enough power to retain date and time even when the computer shuts down with low battery.

@OrangeSVTguy - my PowerBook's not the hi-res one. :-/
Is the Hi-Res one the DVI one (are they one and the same thing?)

@Peterkro - that site's all sold out of my version. :-/ But thanks.

I've seen a few listed on US eBay, but they got different part numbers to iFixit.

iFixit = 820-1686-A

ebay listings = 922-6714 & 922-6711 (they all specify it's for an A1106)

Not sure which is right!? Does Apple do a list?

Here's the dead one I pulled out, just in case anyone else is researching PRAM model numbers. Note it has a weird square battery, not a round one.

It is labelled 820-1813-A, ©2005 which is odd as ISTR the A1106 PowerBook it came from is from 2004. Anyway, it worked until it finally ran out of juice.

Can't remember which one I popped in as a replacement, either a 922-6714-A or 922-6711-A, which had the regular round type battery in it, and that worked also.

Droooooj, could you tell me how difficult the install was? What tools do you need? No soldering, right?

I wasn't considering doing this (PRAM batteries that I found were around $60) but I found one on ebay for $25. And with the iPad so close to what I need, but not *quite* there, (webcam + multitasking) I think I want to get another year out of this PB.

Droooooj,

I realize that this is an old thread, but I wondered how the replacement battery worked out for your G4? I have found a source for new batteries as I have found that all the ones available on the web are dead.

Can you tell me where you're buying it from?


Thanks,

I can confirm that by removing the old battery and replacing it with a new BR3032 battery does work. Make sure it's a lithium ion battery. I used a soldering gun and a razor blade to remove the bad battery from the housing/tabs. Be very careful doing this part. Then I re soldered the new Panasonic BR3032 battery to the tabs, again be very careful not to damage the tabs. I bought the battery at BatteriesPlus, amazon has them too($6-7). Most of the Used batteries on ebay are dead FYI.
