More About the Zinc Air batteries Sizes For Hearing Aids:
Hearing aids come in many different sizes and styles and with different power needs. Larger hearing aids require larger batteries. Additionally, hearing aids for people with severe or profound hearing loss typically require more power and larger batteries. There are four sizes of hearing aid button batteries available on the market.
The sizes from smallest to largest are: 10, 312, 13 and 675.
Hearing aid batteries are all smaller than the diameter of a dime:
Size 10 - 5.8 mm wide by 3.6 mm high
Size 312 - 7.9 mm wide by 3.6 mm high
Size 13 - 7.9 mm wide by 5.4 mm high
Size 675 - 11.6 mm wide by 5.4 mm high

Before rechargeable devices became standard, all hearing aids came with disposable Zinc-air "button" batteries. However, fewer and fewer manufacturers are using these kinds of batteries. For now, they're most typically used in "power" hearing aids for severe or profound hearing loss, which have higher battery demands. Because zinc-air batteries are air-activated, a factory-sealed sticker allows them to remain inactive until it is removed. Once peeled from the back of the battery, oxygen will interact with the zinc in the battery and "turn it on." To get the best performance from a zinc-air battery, wait about one minute after removing the sticker to fully activate before placing it in the hearing device. Replacing the sticker will not deactivate the battery, so once the sticker is removed, the battery will remain in an active state until the power is drained.
Zinc-air batteries remain stable for up to three years when stored in a room temperature, dry environment. Storing zinc-air batteries in the refrigerator has no benefits and could cause condensation to form under the sticker, which could reduce battery life prematurely. Traditionally hearing aid batteries were produced using trace amounts of mercury to assist with conductivity and stabilize internal components, but mercury is no longer used in hearing aid batteries.
Battery life for hearing aid batteries
Non-rechargeable hearing aid batteries can last anywhere from five to 14 days, based on a 16-hour day of wear. This is dependent upon the size of the battery and power needed by the hearing aid. Typically, smaller batteries have shorter battery life than larger ones.
The average lifespan of hearing aid batteries is as follows:
Size 10 - three to seven days
Size 312 - three to 10 days
Size 13 - six to 14 days
Size 675 - nine to 20 days
How to extend the life of a hearing aid battery
While there aren't any foolproof ways to extend non-rechargeable battery life, these tips will ensure the power isn't being wasted. Turn the hearing devices off when not in use and leave the battery compartment door open overnight. Not only will this help keep battery power from being wasted, it will allow any moisture that has built up from the day's use to evaporate overnight. To get optimal performance from your batteries, always store them at room temperature. Heat exposure and humid environments such as a bathroom will shorten battery life. Also, batteries shouldn't be carried loose in pockets, a purse or a backpack where they might come into contact with other metal objects like coins or keys that can short-circuit the hearing aid batteries.
Hearing aid battery safety
According to the National Capital Poison Control Center, more than 3,500 Americans of all ages swallow disposable button batteries every year. If this happens to a person or pet in your home, seek medical attention immediately.
