Hearing Aid Batteries: How Long Do They Last?
Hearing aids are very helpful devices that improve the quality of life for people with hearing loss. But one common question many users have is: how long do hearing aid batteries last? Understanding this can help you take care of your hearing aid and make sure it works properly every day.
Types of Hearing Aid Batteries
Hearing aid batteries come in two main types:
-
Disposable Batteries – These are small zinc-air batteries. They are very common and easy to replace. They usually come in sizes like 10, 13, 312, or 675.
-
Rechargeable Batteries – These batteries can be charged many times and are becoming more popular. They are convenient because you do not need to change them often.
The type of battery you have affects how long it will last. Rechargeable batteries usually last a few years before they need to be replaced, while disposable batteries need to be replaced every few days to weeks.
How Long Do Disposable Batteries Last?
The lifespan of a disposable battery depends on several factors:
-
Hearing Aid Type: Larger hearing aids use bigger batteries that last longer. Smaller, invisible hearing aids use smaller batteries that drain faster.
-
Usage Time: The more hours you use your hearing aid each day, the faster the battery will run out.
-
Features: Hearing aids with Bluetooth or wireless connectivity use more power, so batteries may last a shorter time.
-
Battery Quality: High-quality batteries last longer than cheap or old batteries.
On average, disposable batteries last between 3 to 14 days. For example, small in-ear hearing aids may last 3–7 days, while behind-the-ear models with larger batteries may last 10–14 days.
How Long Do Rechargeable Batteries Last?
Rechargeable batteries are different from disposable ones. You usually charge them overnight, and a full charge can last 12 to 36 hours, depending on the hearing aid and usage. Modern rechargeable hearing aids are designed to last all day, even with streaming audio from phones or TVs.
The battery itself may last 2 to 5 years before it needs replacement. After that, the hearing aid will still work if you replace the battery.
Tips to Make Hearing Aid Batteries Last Longer
-
Turn Off When Not in Use – Always turn off your hearing aid when you don’t need it.
-
Open Battery Door at Night – For disposable batteries, opening the door helps save battery life.
-
Store Properly – Keep batteries in a cool, dry place. Heat and moisture can reduce battery life.
-

Charge on Time – For rechargeable hearing aids, charge them fully every night to avoid sudden power loss.
