ReSound 312 Battery

ReSound Size 312 hearing aid batteries

These disposable zinc-air batteries provide power for hearing aids designed to use the standard size 312 format. Size 312 batteries are identified by their brown colour code, making them easy to distinguish from common alternatives such as size 10, 13 and 675.

Zinc-air technology

The batteries use zinc-air chemistry and remain inactive while the protective tab is attached. Once the tab is removed, oxygen enters the battery and starts the activation process.

Only remove the tab when you are ready to use a battery, as the activation process cannot be reversed.

Features

• Brown colour coding for easy identification
• Mercury-free zinc-air chemistry
• Suitable for compatible ReSound hearing aids
• Can also be used with other hearing aids that require standard size 312 batteries

Compatibility

These batteries can be used with hearing aids designed for standard size 312 zinc-air batteries.

ReSound has used size 312 batteries in many hearing aid models, but not every ReSound hearing aid uses the same battery size. Check the markings on your current battery or the instructions for your hearing aid before ordering.

How to activate a zinc-air battery

1. Remove the protective tab from the new battery.
2. Allow the battery a short moment to activate in the air.
3. Insert it into the hearing aid with the polarity positioned correctly.
4. Close the battery compartment carefully.

If the battery compartment does not close easily, check the battery orientation rather than forcing it.

Tips for hearing aid batteries

• Store unused batteries at room temperature in a dry place.
• Keep loose batteries away from coins, keys and other metal objects.
• Keep batteries out of reach of children and pets.
