I'm sure Rohan does know, but he's been MIA for a bit now.

Did you check in the 60/3000 bible thread?

Cool...post an update if you call or email him. He's a helpful dude but can take awhile to get a response from him if he's busy.

I'm at work, but can check in my service manual when I get home if need be. :)

Also up top there is a drop down for manuals, the 3k service manual is there.
In the parts lists is says:

4. CPU P.C. Board

EZ403706J - Battery Lithium CR2032E


These batteries are in Walgreens, CVS, Target, Walmart, Radioshack, every store that sells watch batteries. it's almost the size of a U.S. quarter and it's a very common and easy to find universal battery.

Is that the battery your looking for?

right :lol: I have those also.

It's also known as a regular ole motherboard battery. Most of us have seen this same shiny silver coin looking battery on motherboards.

Hi there,

I hope this will help/give ideas.
A customer of us had problems to change/find the correct vertical soldered CR2032E. The ones he found hadn't the same pin implementation so I made this small mod for his 3k to make things easier in the future :

So what we have :

You see you have to remove all the boards to access to this and then a quite precise soldering job waits for you. There are quite a lot of tiny tracks in this area of the mobo ... touchy.

Then I decided to remove the battery from here so the customer can change it himself without removing anything and use very common batteries CR2032.


I use a lot of these "braces" (it's the word google translate gave me ...^^ you can see some under the SCSI mod we also made), very useful.

And here is the small PCB with battery holder. Job done !

Not very smart, this costumer doesn't need me anymore now ....
