How to Sort Watch Batteries

Why You Need to Sort

There are a few reasons why you need to sort your used watch batteries before shipping to Watch Battery Buyers.
*First, sorting is necessary to be certain there are no mercury-based batteries in your shipment. Mercury-based batteries are banned in the USA and probably everywhere in the world. Mercury-based batteries must be properly disposed of at your local county waste facility. Most counties / states in the USA have a forgiveness program to dispose of these at no charge.
*Second, because of the nature of the chemical makeup of lithium batteries, they are not legal to ship in combination with silver oxide batteries. Lithium batteries are considered a hazardous material under federal regulations and silver oxide batteries are not.
*Third, shipping a 'clean' batch of silver oxide batteries enables us to more quickly and more accurately assess your shipment which means we can more quickly send your payment.
*Finally, shipping only silver oxide batteries helps keep our shipping fees down and therefore operational costs down, so we can pay higher rates to you.

Tips for Sorting Watch Batteries by Hand

1) Remove All Watch Batteries Larger in Diameter Than a Dime

FASTSort Watch Battery Sorting TrayAll 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 like the one shown to the right (available at FASTSort). With a sorting tray, all you do is dump your watch batteries through the tray and presto... 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 an exhaustive list, 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. Note that 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

It is recommended to create a separate pile for watch batteries labeled in Chinese. Evidence suggests that many 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 our Silver Oxide Watch Battery List below. Contact Watch Battery Buyers to find out if we have processed those manufacturers before and if the actual silver content is known.

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 Watch Battery Buyers expects to receive in shipments and will result in the highest payouts.
