I have an old Dell Inspiron 8200 laptop. Still mostly works, but the clock battery has died so everytime I power it on I need to go into the BIOS and set the proper clock time. From what I've been able to tell, replacing this battery is non-trivial, but I haven't found a clear answer.

How do I replace the clock battery? And how do I buy a replacement?

Here is Dell's manual page on replacing the "reserve battery" on the Inspiron 8200.

Here is a model 2664E CMOS Battery (7.2V, 15MAH, 3 pin) for $35, does this look right? It would be nice if Dell's manual gave a part number or some kind of spec.

I always seem to find the answer after I ask someone else for help :) Does the one I linked to look right? – jacobsee Nov 25 '09 at 17:28
yep, that looks quite right. – Molly7244 Nov 25 '09 at 18:16
