Two Types of Hearing Aid Batteries
There are two main types of hearing aid batteries: rechargeable batteries and standard disposable batteries. Each has its own advantages.
​
Rechargeable Batteries
Rechargeable batteries are built into your hearing aids and don’t need to be replaced often. You simply place your hearing aids in a charging dock or case at night, and they’re fully powered by morning.
​
Benefits of rechargeable batteries:
​
-
No need to regularly buy and replace batteries
-
Easy to recharge overnight
-
Environmentally friendly-less waste
-
Great for those who have trouble handling small items
Â
Keep in mind: rechargeable hearing aids need to be charged daily. If you forget to charge them, they won’t work until you recharge.
Â
Standard Disposable Batteries
Disposable hearing aid batteries, also called zinc-air batteries, are small and round. They start working when you remove a sticker that lets air in.
​
Benefits of disposable batteries:
​
-
Easy to replace when they run out
-
Useful when a power source isn’t available
-
Battery life varies based on size and hearing aid type
Â
Disposable batteries are a good choice for people who travel often or don’t always have access to a charger. However, they do need to be replaced regularly, which adds to long-term cost.
Disposable Hearing Aid Batteries
Disposable batteries come in different sizes to fit various types of hearing aids:
-
Size 10 – Smallest battery, used in tiny hearing aids; lasts about 3-5 days
-
Size 312 – Common in behind-the-ear (BTE) and in-the-ear (ITE) styles; lasts about 5-7 days
-
Size 13 – Slightly larger, used in stronger hearing aids; lasts about 6-14 days
-
Size 675 – Largest battery, used in high-powered devices; lasts about 9-20 days
To help you choose the right battery size, each type is color-coded on the packaging:
-
Size 10 – Yellow
-
Size 312 – Brown
-
Size 13 – Orange
-
Size 675 – Blue
Battery life depends on the size of the battery, the type of hearing aid, and how often you use it.
-
Small batteries:Â 3-7 days
-
Larger batteries:Â 6-20 days
-
Rechargeable batteries: usually last one full day, then need to be recharged nightly
Â
Using features like Bluetooth or streaming can drain batteries faster.
Tips to Make Hearing Aid Batteries Last Longer
-
Keep batteries in a cool, dry place
-
Don’t store them in the refrigerator
-
Keep them away from metal objects (keys, coins) to avoid short-circuiting
-
Remove the sticker only when you’re ready to use the battery
-
Let it sit for 1–2 minutes before inserting it into the hearing aid—this helps activate it fully
-
Charge your hearing aids every night
-
Avoid overcharging—always use the charger made for your hearing aids
-
If storing hearing aids for a long time, turn them off to save battery life
-
You may need new batteries if:
-
Sounds become faint or unclear
-
Your hearing aid stops working
-
You hear beeping sounds (a low battery warning)
