Hearing Aid Batteries

The easiest thing about hearing aids is finding the right batteries to power them. Over the years, the process has been simplified by number and color. Even with the modern advancements with hearing devices, the batteries remain uniform for ease of use. Grace Hearing and Language Services provides batteries to the most popular hearing solutions in the industry.

Current technology

Batteries in old and new hearing aids are more likely to use zinc-air technology than any other type. The result is a long-lasting battery with a low amount of interference. Using zinc-air batteries means respecting their expiration rules. A tab or sticker seals everything in place for zinc-air technology to keep it from drying out. They should only be opened when ready for use in a compatible hearing aid device. The type of environment these batteries are used in will factor into their life expectancy. It isn’t uncommon to have the same kind of battery last an additional week, but then have a shorter lifespan when the temperature changes the next month. With hearing aid technology advancing to use different platforms, battery usage will continually change. Updated features like streaming and Bluetooth are more likely to use more power than traditional features. 

Battery types

Hearing aids still maintain four different battery types, so the core has remained uniform. Every hearing aid provider has a preference, while some are mandatory choices due to size restrictions. Currently, blue (675), brown (312), yellow (10) and orange (13) are the main choices. Blue has the longest battery life, while yellow has the shortest. Each has its own set of benefits that make it useful for a particular hearing device. When size restrictions are considered, it becomes easier to notice the subtle differences between the four. Replacing dead batteries in a hearing aid is a simple task made easier by the color chart. It’s impossible to mistakenly use the wrong batteries in a product and cause damage. 

Rechargeable batteries

Rechargeable batteries prevent you from having to swap out or purchase disposables frequently. Instead, a recharging station is used when necessary to bring the batteries back up to 100%. This station can be placed anywhere but should be kept out of reach of small hands, furry companions, and water damage. The nightstand is a popular option, and lets you charge your heading aids while asleep.
