Hearing Aid Batteries
Batteries are essential to operating your hearing aids. Batteries are typically available from a variety of sources such as retail stores, pharmacies, grocery stores, and through online retailers.
I encourage you to purchase batteries through the office because I receive them from the manufacturer. I know they have been stored properly and are always freshly stocked. Also, if you forget what battery size you need I can ensure that you purchase the correct size.
A standard hearing aid battery lasts anywhere from 3 to 14 days based 16 hours per day of wear. Usage life depends on size of batter, the hearing loss of the individual, the ambient evironment in which the aids are used and also the age of the batteries themselves..
Batteries come in varying sizes. These are universal among all manufactures. The packaging is also color-coded to match the size so if you can't remember the number you can remember the color.
Yellow cards are #10
Brown cards are #312
Orange cards are #13
Many manufacturers are also offering rechargeble options for their hearing aids. This allows you to insert your hearing aids into a charging device overnight and the aids are ready to wear the next day. This is a great option is you have dexterity issues or simple don't want to hassle with changing batteries on a weekly basis.
Tips about batteries
Change your batteries if you have to turn up the volume more than usual.
Hearing aid batteries can lose power very suddenly, so it's a good idea to have an extra set of batteries with you at all times.To protect against discharging your backup batteries, keep them away from coins, keys or other metal objects.
Hearing aid batteries are activated by oxygen. Do not remove the tab from the battery until you are ready to use it.
When you're not wearing your hearing aid, turn it off by opening the battery door. This minimizes battery drain potentially giving a longer to usage life to the battery.
Store hearing aid batteries at normal room temperatures. Do not refrigerate or place in the freezer or leave them in a hot car.
Leave the battery compartment of your hearing device open at night so moisture can escape. Doing so will keep the battery from corroding and damaging the hearing aid.
Remove dead batteries immediately. A completely discharged battery may swell and become difficult to remove. Do not store hearing aids with batteries in them long term for the same reason.
