My computer clock battery died. It had a CR2032. I bought a CR2025 at a store going out of business (No Returns). Both say they are 3v. The CR2025 is a little thinner, but otherwise they are the same size. Is there any reason not to use the 2025? --------------

The 25 at the end is 2.5mm verses the 3.2 mm you were using.. It'll work just fine but not last as long. Probably it'll last long enough for the rest of that computer's life. the 20 at the start is the width of the cell. I am doing this from memory but it should be correct. Jamie.

Put a dime on the + end as a shim. It won't last as long as the 2032, but should work. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

For a 2032, the 20 means the diameter (20mm) and the 32 means the thickness (3.2mm). The 2025 is 2.5mm thick and the even thinner 2016 is 1.6mm thick. Most sockets are designed for a particular thickness so as others have noted, the 2025 will not fit the socket correctly. Regards, Simon.

Many sockets don't use the swing over spring arm, the cell is wedged in the socket via a side spring to hold it. This means it'll hold all the CR20xx sizes.. Your key FOB on most cars are a good example. At least the one on my jeep and Sante Fe are. Jamie

Teh contacts are on the side of the case part of the battery, so it seems to work just fine. This is an older IBM computer, and it needs a new battery every 8 months or so. It always has since I bought it around 2004. Seems that IBM computers all had (or still have) this problem. I'll live with it. At least they dont seem to have failing capacitors and the other failures that some other brands are known to have. Aside from eating batteries, these IBM systems seem to run forever. I should mention that I always shut off a power strip for the computer and all components hooked to it. I was told that leaving it plugged in and just shutting off the power switch would save batteries. But I'd probably pay for it in my electric bill, and possibly lose a computer from lightning. Lightning strikes are common on farms. I tend to lose a modem at least once a year and recently lost a DTV converter. I'd have to disconnect the antennas and phone lines and darn near everything else to prevent this. That gets to be a major hassle.

But what's the problem? You just have to reset the time every time you boot.> =A0But I'd > probably pay for it in my electric bill, and possibly lose a computer > from lightning. =A0Lightning strikes are common on farms. =A0I tend to lo=se> a modem at least once a year and recently lost a DTV converter. =A0I'd > have to disconnect the antennas and phone lines and darn near everything > else to prevent this. =A0That gets to be a major hassle.Get a UPS that offers adequate surge protection.
