Specs: Windows 7
Having a terrible time finding the right replacement CMOS battery for my Alienware M9700 laptop. Can't find any info on the Alienware or Dell websites. Anybody know where I can buy a compatible battery?

Isn't there a number or voltage on the old battery.

I don't know about laptops but a common battery for desktops is Panasonic CD3032 - 3Volt.

Battery is encased in insulation so I can't see the markings on the battery. It also has leads and a very small plug that connects to the motherboard. But you gave me a great idea. Maybe I can cut off the insulation and hopefully there are markings on the battery underneath.

No it is coin shaped. Looks a lot like this one:

Yep that's it. Unfortunately they show you how to swap it with very nice instructions, but don't bother to tell you where to buy one.

You could probably make one up using the old one. I would guess the leads may be soldered to the battery. Googling for CMOS batteries brought up this place.

Good find OtH. Probably just cut the shrink tubing off the old battery and match it up with one on that page.

Or get the appropriate battery, solder the leads on, replace the shrink wrap and give it a try.

If the leads connect directly to the battery they're probably spot welded. Solder doesn't 'stick' to those surfaces. Or it'll be a battery with terminals spot welded and then wires soldered to the terminals.

If it's a 3 V lithium you may be able to get by with a regular 2032 disk battery as a replacement. Put the battery in a salvaged battery holder from a junked motherboard. Solder the existing wires to the holder and wrap with the insulation.

Bah, humbug
