What am i suppossed to do with the batteries i take of the motherboards. I have a box of them do i have to bring them somewhere to dispose of them. Does anyone buy them. Or just chunk them in the garbage?

I just chunk mine. When someone gives me an economical way of recycling them I will gladly do it.
Lithium button batteries need proper disposal take to Lowes or home depot or battery plus store to get rid of them.
For those the quantity you need before someone will buy them is pretty large. Like hobo said plus Best Buy and some others
You can also check with your local pharmacy, since those CR2032's are button cells and often end up in things which people tend to buy at Rite Aid or Walgreen's. Last, I knew, pretty much every pharmacy in my area took them.
Oh! I've been meaning to say, regarding 2032's, that they are great for other purposes because so many things use them. And the best part is that, if you are pulling them from newer boards, they often have hours of useful life left for powering other low-draw applications. I use mine for those dollar-store LED tea lights and votives, which is great because those batts are not really cheap to buy and it sucks to not have them if the power goes out for a while. Diabetes testers use them, too, as well as thin calculators, small remotes, and some toys.
If they are silver oxide, you of course want to save them until you have a sizable quantity and then sell them for someone else to refine.

At the heart of science is an essential balance between two seemingly contradictory attitudes--an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense. -- Carl Sagan
To be honest, you have to get to know the batteries themselves. There are a few tricks you can use however.
Tips for Sorting Watch Batteries by Hand:
1) Remove All Watch Batteries Larger in Diameter Than a Dime
Quickly sort by size, silver oxide watch batteries are smaller than 1/2 inch. So anything larger should be removed. Save EVEN MORE time by building or buying a 1/2 inch metal mesh sorting tray. With a sorting tray, all you do is dump your watch batteries through the tray and all the watch batteries greater than 1/2 inch are separated.
2) Remove All Watch Batteries Labeled: A, C, D, E, L, M* or 3V
A watch battery label beginning with A, C, D, E or L indicates the battery is NOT silver oxide. This is not all batteries, however these are the most common. For batteries that look VERY old and the model number starts with an M, chances are high this is a mercury type battery that should be disposed of appropriately. Timex currently produces watch batteries with model numbers M and MA that are actual silver oxide batteries.
Also, watch batteries labeled 3V can be removed because silver oxide watch batteries are all 1.55V.
3) Remove All Watch Batteries Stamped: Silver Oxide, Silver Oxide Cell, Silva Cell or Silver Cell
A watch battery stamped with any of the above phrases has been found to indicate that the battery is a forgery and it is NOT silver oxide. Watch Battery Buyers has tested many of these watch batteries and in every case they were fake.
4) Remove All Watch Batteries Labeled in Chinese
Make a separate pile for watch batteries labeled in Chinese. Chinese manufacturers use 50% less silver in their silver oxide watch batteries and some use as much as 90% less silver compared to the manufacturers on the Silver Oxide Watch Battery List below.
5) Use the Silver Oxide Watch Battery List
The following manufacturers are widely recognized in the industry for producing high quality silver oxide watch batteries, all with consistent silver content. These are the manufacturers and models that will result in the highest payouts.

Other batteries that might contain silver are made by Bulova, GP, IEC, and Timex but I cannot find the information on them, you will have to look them up yourself and add them to the list. If you do, post them here please for others to use.
This is in regards to what are commonly called watch batteries, however, I have seen other batteries that are not watch batteries, of odd shapes in different types of computer and electronic equipment that were silver oxide batteries so keep an eyeball out.
Any unusual size battery made for a special application, specially if it's military, should be checked for being a silver oxide battery. Several years ago I actually bought a few really large silver oxide batteries that were sold as military surplus but not for the value of their silver content. I have never seen the batteries before, or since. I am not sure who made them because there was no manufacturer marks on the batteries themselves. So check every battery that you are not sure of. I would suggest with the button batteries, setting aside anything you are not sure is not a silver oxide battery, and finding information on them when you have time.
Here is a primer of sorts
https://www.scribd.com/doc/17876402/...tton-Batteries
I'm sure if you do some research on Scribd, or other sites you can probably find a lot more information on silver oxide batteries. The Silver Institute is a good place to better understand how silver is used in industry.

And good luck!

All the motherboard batteries I've seen have been lithiums, usually larger than a dime, and 3V. I haven't saved any for silver scrap. Some laptop CMOS may be different, though.
I've only seen one silver oxide label that I recognized and it came out of a small calculator from the early 1990's. I really have no idea what the most common application of Ag in button cell batteries has ever been. But that doesn't stop me from looking.
