Can All Batteries Be Replaced?
Yes, you can replace all hearing aid batteries, regardless of whether they are disposable or rechargeable. Replacing the batteries requires the use of specific shielded batteries, as they are designed to prevent any possible damage to the hearing aid. Be sure to always use this type of battery rather than one of identical size from another device.
Although you can replace batteries, some can be quite expensive. However, there are a couple of tricks that can preserve your battery’s life and maximize the use you get from it. Turning off the hearing aid when it isn’t in use, leaving the battery flap open at night, and storing batteries at room temperature are just a few examples.
Types of Hearing Aid Batteries
Hearing aid batteries come in many sizes and varieties, so it’s essential to know which one is right for your device. Rechargeable batteries are available for most behind-the-ear hearing aids. As for disposable zinc-air batteries, there are four standard sizes, all of which are color-coded for user convenience:
Size 10 — Coded with the color yellow, they are typically used for smaller hearing aids, and have a life of 3–10 days.
Size 13 — Color-coded using orange, these are commonly used for behind-the-ear hearing aids, and can last for 1–2 weeks.
Size 312 — These are coded by the color brown, can be used for both receiver-in-ear and in-canal devices, and have an average life of 3–10 days.
Size 675 — Color-coded using brown, these are the largest on the list. They also have a longer life, and last from 9–20 days.
Always be sure to consult a hearing care professional to choose the battery which is properly-suited to your hearing device.
Can Rechargeable Batteries Be Replaced?
Rechargeable batteries can indeed be replaced, as they can lose their charge over months of extended use. They are meant to charge while you sleep so that they can be at full power when you awake to use your hearing aid. However, if you notice decreased performance or that they fail to hold an adequate charge, it may be time to replace them.
If you are looking to replace your rechargeable batteries, be sure to consult with an audiologist or hearing aid specialist. Choosing the specific battery model for your particular hearing aid is an essential part of maintaining your device. Using the wrong battery can cause irreparable damage.
