Disposable zinc-air batteries (like size 312) activate when exposed to air. Proper handling before and during use can improve their performance.

• Wait to Activate: When you peel the protective tab off a new battery, wait for five minutes before placing it in the hearing aid. This allows the zinc-air to fully activate, delivering a better charge life.
• Open Doors Overnight: Every night, open the battery door completely. This turns the device off and allows any trapped moisture to evaporate, preventing corrosion and saving power.
• Store Correctly: Avoid storing spare hearing aid batteries 312 (or any size) in the refrigerator or in direct sunlight. Keep them sealed in their original packaging at room temperature.
• Reduce Streaming: High-power features like Bluetooth audio streaming drains batteries faster. Beng aware of this will help recognise how quickly your batteries may last.

Rechargeable hearing aids offer convenience, but maintaining the lithium-ion cells requires different habits than disposable batteries.

To extend the longevity and daily charge of your rechargeable hearing aids, always perform a full charge cycle overnight, avoid frequent partial charging (known as 'topping off'), and use a drying station to remove performance-draining moisture.

• Charge Every Night: Treat them like your mobile phone—a full overnight charge ensures they are ready for the entire next day.
• Use the Drying Function: If your hearing aid charger has a drying function (gentle heat or UV-C), use it. Moisture makes the battery work harder and degrades its capacity over time.
• Mind the Temperature: Try to avoid leaving your rechargeable devices in extreme heat (like in a car in the summer) as this can permanently reduce the battery's lifespan.

The answer varies greatly depending on the battery type, size, and your device's technology.

Disposable hearing aid batteries typically last between 3 to 14 days, depending on their size and how much wireless streaming or noise reduction processing your hearing aids are performing.

Rechargeable aids, once fully charged, are designed to last for a minimum of 24 hours. If your new rechargeable device is lasting significantly less than a full day, it’s time to visit an Amplifon hearing aid clinic.

The cost of hearing aid batteries Australia depends on the brand, size, and where you buy them.

While costs vary, buying certified hearing aid batteries in bulk from a reputable provider like Amplifon offers the best value.
