DISCOUNT HEARING AID BATTERIES

Battery Sizing, Information, and Cross Reference

1. What are the common battery sizes?
Hearing aid batteries come in 4 common sizes. They are 10, 13, 312 and 675. To identify the size, most manufacturers use an industry standard color code on their zinc air tabs and packaging. Yellow for Size 10, Brown for Size 312, Orange for Size 13 and Blue for Size 675.

Manufacturers often place letters before or after the battery size to designate their factory reorder number. For instance, 13A or R10ZA are both size 13 batteries.

2. Are batteries interchangeable among manufacturers?
Manufacturers have different battery quality and performance; however the battery dimensions are standardized within the industry. For instance, a size 13 battery across manufacturers should fit in your hearing aid. Just match the size designated by the color code above.

3. How long will my batteries last?
Battery life is determined by the type and amplification of your hearing aid as well as the hours you wear your hearing aid. Your hearing care professional can tell you the battery life you can expect.

4. How should I store my batteries?
You should store your hearing aid batteries at room temperature. Avoid storing your batteries in hot places since heat will shorten the life of the batteries. Refrigeration is also not recommended. Batteries should not be carried loose in your pocket or purse. If a battery inadvertently comes into contact with a metal object such as coins or keys the battery may discharge, leak or in rare incidences even rupture. To prevent this from occurring keep unused batteries in the original packaging or in a battery holder.
Batteries that have been fully discharged can be thrown in your regular trash. Store and discard batteries in places that cannot be reached by infants or children. If a battery is swallowed, see a doctor immediately. For recommended treatment, call the National Button Battery Hotline collect at 202-625-3333.

5. Why is there a tab on my zinc battery?
A zinc air battery uses air outside the battery as a source of power. The factory applied tab seals the air holes in the battery and ensures freshness until you are ready to use the battery. Do not remove the tab until you are ready to use the battery. To activate the battery, you simply remove the tab. After removing the tab, wait about one minute prior to inserting the battery into your hearing aid. This allows sufficient time for the air to enter and activate the ingredients. Replacing the tab when the battery is not in use will not extend the battery life.
