Hearing aid batteries provide power to your advanced hearing aids. Here you need to know about hearing aid battery size, lifespan, storage, brands and purchase.
Two main types of hearing aid batteries
For the greater part of the listening device clients, ordinary decision for amplifiers batteries are the catch cell, which is a sort of Micro Batteries. These miniaturized scale batteries are the little, level, round shape. Accordingly it would seem that a standard catch. The most widely recognized sort is a zinc-air button expendable battery. These are air-actuated so they don’t begin losing their capacity until getting contact with air.
Many new Hearing aid batteries models come with rechargeable batteries. These batteries are usually recharged at night, when the hearing aid wearer extracts their hearing power to sleep. Until now, rechargeable batteries are generally available only for the backstage style of hearing aids. Rechargeable hearing aid brands on the market from manufacturers in 2019 include:
- Oticon Opn S
- Phonak Audeo Marvel
- Starkey Livio AI
- ReSound LiNX Quattro
- Widex Fusion2
Standard disposable batteries
Zinc-air button disposable batteries, also known as “button batteries”, are other common options. Because zinc-air batteries are air-activated, the factory-sealed sticker allows them to remain idle until removed. When stripped from the rear of the battery, oxygen will collaborate with the zinc in the battery and “turn it on. To get the best performance from a zinc-air battery, wait approximately one minute after removing the sticker to activate fully before placing. It is in the hearing aid. Replacing the sticker will not deactivate the battery, so once the sticker is removed, the battery will remain in the active state until the power goes out.
Zinc-air batteries remain stable for three years when stored in a room-temperature, dry environment. Placing zinc-air batteries in the refrigerator is of no use and condensation may occur under the stickers, reducing battery life over time. Traditionally hearing aid batteries were manufactured using trace amounts of mercury to improve conductivity and balance out inward parts, however mercury is never again utilized in portable amplifier .
Sizes of disposable hearing aid batteries
Portable hearing assistants come in a wide range of sizes and styles and with various power needs. Bigger listening devices require bigger batteries. Also, portable amplifiers for individuals with serious or significant hearing misfortune normally require more influence and bigger batteries.
There are five sizes of amplifier batteries accessible available. The sizes from smallest to biggest are: 5, 10, 312, 13 and 675. Size 5 portable amplifier batteries are once in a while utilized. The four most normal listening device battery sizes are on the whole littler than the width of a dime:
- Batteries Size 10 – 5.8 mm wide by 3.6 mm high
- Batteries 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
Color-coding for disposable hearing aid batteries
Because the size difference can be difficult to notice and difficult to remember, battery packaging is color coded so that the right people are easy to find and purchase.
- Batteries Size 10 – Yellow
- Batteries Size 312 – Brown
- Size 13 Battery – Orange
- Size 675 Battery – Blue
Battery life for hearing aid batteries
Non-rechargeable hearing aid batteries can last anywhere from five to 14 days, depending on the 16-hour day. This is dependent on the size of the battery and power required by the hearing aid. Generally, smaller batteries have longer battery life.
The following is the average age of hearing aid battery:
- Batteries Size 10 – Three to Seven Days

Turn off the hearing aids when not in use and leave the battery compartment door open overnight. Not only will this help protect battery power from being wasted, it will allow any moisture that will evaporate overnight from day to day use.
To get ideal execution from your battery, consistently store them at room temperature. Heat exposure and humid environments such as bathrooms will reduce battery life. In addition, the batteries are carried in a pocket, a purse or a backpack where they may come in contact with other metal objects such as coins or keys that may short-circuit the hearing aid battery.
