Hearing Aid Batteries
Hearing Aid Batteries and Rechargeable Options
Allen Audiology stocks all standard hearing aid battery sizes — 10, 13, 312, and 675 — at our Allentown and Bethlehem offices so you can pick them up during any visit. We also carry the latest rechargeable lithium-ion models from leading manufacturers, which eliminate disposable batteries entirely. Whether you prefer the simplicity of a nightly charging cradle or the flexibility of traditional zinc-air cells, our audiologists can match you with the power solution that fits your lifestyle.
Tips for Getting the Most from Your Batteries
Small habits make a noticeable difference in battery performance. For disposable zinc-air batteries, wait a full minute after removing the tab before inserting them — this allows the cell to activate properly. Store unused batteries at room temperature in their original packaging and keep them away from coins or keys that can cause a short circuit. For rechargeable hearing aids, placing them in the charger each night ensures a full day of power. If your battery life has dropped noticeably, your audiologist can check whether a setting change or a device service is needed.

“The doctor could have easily sold me a product that I don't need, but she was honest and up front, advising that the benefits would not override the drawbacks. Very impressed with the honesty and professionalism!”— James Davis

Frequently Asked Questions
Battery life depends on the size of the cell, the power demands of your hearing aid, and how many hours a day you wear them. As a general guide, size 10 batteries last three to five days, size 312 batteries last five to seven days, size 13 batteries last seven to ten days, and the larger size 675 batteries can last up to two weeks.
Rechargeable hearing aids are an excellent option if you want to avoid the hassle of changing tiny batteries every few days or if you have dexterity problems. You simply place the devices in a charging cradle overnight and wake up to a full day of power, typically 18 to 24 hours, including several hours of Bluetooth streaming.
Several factors can shorten battery life: increased Bluetooth streaming, higher-than-normal volume settings, humidity and moisture exposure, extreme temperature exposure, improper battery storage, or using batteries that are beyond their expiration date.
If the change seems sudden and unexplained, schedule a visit with your audiologist. We can inspect your devices and determine whether the issue is with the batteries themselves or with the hearing aid's electronics.
Yes. Both our Allentown and Bethlehem offices carry all standard zinc-air battery sizes — 10, 312, 13, and 675.
We source batteries from reputable manufacturers to ensure consistent quality and shelf life. If you use rechargeable hearing aids and your built-in battery is no longer holding a full charge, we can also arrange a replacement through the manufacturer.
