Zinc Air Hearing Aid Batteries

Zinc air hearing aid batteries are the latest in hearing aid battery technology. Through a unique construction that utilizes air from outside the battery, these batteries pack maximum energy into each battery cell, allowing for an extremely long lasting hearing aid battery. Combining zinc and oxygen creates a steady long-lasting stream of energy to power hearing aids longer. This technology allows for fewer battery replacements, clearer tones and fewer volume adjustments. Cheap Hearing Aid Batteries Canada only uses zinc air hearing aid batteries.


  • Inexpensive
  • Long shelf life (2% self-discharge rate/year)
  • Low Cost
  • Compact size
  • Mercury Free

Zinc Air batteries are environmentally friendly. They pass the U.S. Environmental Protection Agency’s toxicity tests for Mercury, Cadmium and Lead.

Hearing Aid Battery Care

How should I store and carry my batteries?
You should store your hearing aid batteries at room temperature. Avoid storing batteries in hot places since heat will shorten the life of the batteries. Refrigeration is also not recommended. Our hearing aid batteries require little to no care and have the longest shelf life of any battery out there.

Batteries should not be carried in your pocket or purse since metal objects such as coins and keys can short out batteries. 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

Why is there a tab on my battery?
A zinc air battery uses air outside the battery as a source of power. The tab seals the air holes and ensures freshness until you are ready to use the battery. To activate the battery, simply remove the tab, wait one minute to allow air to enter and activate the ingredients, and insert the battery into your hearing aid. Replacing the tab when the battery is not in use will not extend the battery life.

Will Using My Dry Aid Kit Affect My Hearing Aid Battery Performance?

It depends. Dry aid kits work well in the summer heat and humidity to keep the circuitry, electronic components and batteries free of moisture from the air and/or perspiration. During these times, batteries can actually take on moisture while the hearing aid is being used in humid conditions or exposed to perspiration. Dry aid kits can assist in moderating the moisture in the battery during these times to prolong stable battery life. Optimally, the battery should be removed from the aid inside the kit. The accumulated moisture in both the battery and the aid can then be eliminated. If you have experienced issues in the past with batteries rusting or swelling, removing the battery when the aid is not in use is strongly recommended. Dry aid kits are less necessary for battery maintenance in the fall/winter when dry conditions usually minimize perspiration and salt, and humidity levels are low. In most parts of the country, drying conditions set in during the fall months and go into winter. A good rule of thumb to use is when your skin feels dry and needs moisture, it is time to stop using your dry aid kit. Using a kit when climate conditions are dry can prematurely dry the cell and lead to shortened battery life.

Rechargeable Hearing Aid Batteries

Rechargeable hearing aid batteries are another potential alternative to standard one-use hearing aid batteries. Rechargeable batteries generally last for 12 hours per charge, meaning that they must be recharged every night if you wear your hearing aids all day. It is a common misconception that rechargeable batteries save money. Rechargeable batteries generally last around 300 cycles meaning they have to be replaced every year. The high initial cost of rechargeable batteries ensures that there are little to no cost savings through their use. Rechargeable batteries also come with certain disadvantages, such as: one must remember to put them on the charger every night, the hastle involved with bringing your charger on a trip and the inconvenience of forgetting to charge the batteries.

Battery Sizing

Consult with your hearing care professional or the documentation that came with your hearing aid to determine the appropriate hearing aid battery size for your hearing aid. The most commonly used hearing aid battery sizes are Size 10, Size 13, Size 312 and Size 675. To identify the size, most manufacturers use an industry standard color code on their zinc air hearing aid battery tabs and packaging.

Hearing Aid Battery Size Chart

You'll notice that different manufacturers often place different letters before or after the battery size. For instance, 13A or R13ZA may look different, but both codes represent size 13 batteries.
