Mercury batteries, have either been out-lawed, or for whatever reason, no longer are being manufactured and made available for purchase.
The current batteries, called Zinc-Air, are manufactured by Duracell,Eveready,or Rayovac.
These companies will assign a private label to their product, primarily for marketing purposes.
There are no differences in the hearing aid batteries provided from the battery manufacturer,regardless of the label they put on the package.
All Manufacturers have agreed to a standarized identification system.
The batteries are provided with a tab placed over openings to the internal cell, to prevent the cell from being activated. Until the tab is removed, or the seal is broken, and it leaks, the batteries have unlimited shelf life.In other words, the batteries may have a shelf live for over 5 years.
The color Yellow has been assigned to size 5 battery.
This size is used in most small hearing aids. Because of its size it has the shortest battery life.
The color Orange,has been assigned to size 13. It is larger than size 10 and provides much longer battery life. This size is used in every type hearing aid made.
The size 312 has been assigned the color of Brown. It is the same diameter as size 13 but is half as thick and lasts only half as long. It is used only because of size considerations and cosmetic purposes.
The size 675 has a Blue Tab, and is usually used only with BTE hearing aids. The BTE hearing aids usually provide the most power and the battery drain and consumption is the greatest. Being the largest size battery used in hearing aids, provides the longest battery life

If you're not buying them at Costco, you're paying too much.

Longest lasting I have found to date.


Ridiculous. Like anything else you get what you pay for.
