What types of batteries do hearing aids use?
Hearing aids use zinc-air batteries — there are four main sizes: 675, 13, 312, and 10. The size that you need will depend on the hearing aid you have.
The AIR, PRO, and, CONTROL models use a size 13 battery (orange tab).
The LUX and CORE models use a size 312 battery (brown tab).
The VOLT is our rechargeable model, and therefore uses a rechargeable lithium-ion battery.
Both sizes of hearing aid batteries are readily available at most corner drug stores. You can also order the correct battery for your hearing aid from us here.
What is the adhesive tab for?
The small, adhesive, colored tab on the battery is a protective seal. Because zinc-air batteries are air-activated, this tab allows them to remain inactive until it is removed. A hearing aid battery begins to discharge as soon as the tab has been removed — so don’t remove it until you’re ready to use it.
How do I change the battery?
- Grab a new battery and remove the adhesive tab to activate the battery. Wait one (1) FULL minute for the battery to become fully operational.
- Use the nail grip on the battery door to open the battery compartment.
- Remove the old battery with the magnet on your cleaning tool, or turn the device over and let the battery fall into your hand.
- Insert the new, activated battery with the positive (+) side facing up. Then close the battery compartment.
note: If the battery door does not close easily, the battery may be inserted upside down.

- Batteries can be harmful if swallowed. Keep out of reach of children and pets. If a battery is accidentally swallowed, seek medical attention immediately or call the National Battery Hotline at 800-498-8666.
- For prolonged periods of non-use, open the battery compartment and remove the battery to prevent corrosion.
- Store batteries in original packaging.
- Do not use expired, unsealed, or corroded batteries.
- Do not leave dead batteries in the hearing aid. Replace them immediately.
