Pro Tips

Extend Your Battery Life

Simple habits that can significantly increase how long your hearing aid batteries last.

01

Open Battery Door at Night

When not wearing your hearing aids, open the battery door to break the circuit and prevent drain. This simple habit can add days to your battery life.

02

Let Batteries "Breathe"

After removing the tab from a zinc-air battery, wait 3–5 minutes before inserting it. This allows oxygen to fully activate the battery for maximum output.

03

Store at Room Temperature

Keep batteries at 68Β°F (20Β°C). Avoid refrigerators β€” condensation damages batteries. Keep away from metal objects like coins or keys that can cause short circuits.

04

Manage Bluetooth Streaming

Streaming audio via Bluetooth can increase battery drain by 30–50%. Limit streaming when battery is low or use a larger battery size (Size 13 or 675) for heavy streaming use.

05

Use a Dehumidifier

Moisture is the enemy of hearing aid batteries. Store your hearing aids in a dehumidifier case overnight to remove moisture and extend both battery and device lifespan.

06

Keep Contacts Clean

Dirty battery contacts reduce efficiency. Use a soft, dry cloth to gently clean the battery contacts and compartment. Never use water or cleaning solutions on battery contacts.

Connectivity

Bluetooth Pairing & Troubleshooting

Step-by-step guidance for connecting your hearing aids to smartphones, TVs, and other devices.

πŸ“±

Pair to iPhone (iOS)

Go to Settings β†’ Accessibility β†’ Hearing Devices. Turn your MFi-certified hearing aids off and back on to enter pairing mode. Tap your hearing aid name when it appears and select "Pair" on both pop-up prompts.

MFi Certified
πŸ€–

Pair to Android

For ASHA-compatible aids, go to Settings β†’ Accessibility β†’ Hearing Aid Compatibility. For standard Bluetooth, go to Settings β†’ Bluetooth, turn hearing aids on in pairing mode, and select them from the device list.

ASHA Protocol
πŸ“Ί

Stream from TV

Most hearing aids require a TV streaming accessory (e.g., Signia StreamLine TV) that plugs into your television's audio output and transmits audio wirelessly to your hearing aids. No phone needed.

Accessory Required
πŸ”§

Bluetooth Not Connecting?

Try these fixes: 1) Turn Bluetooth off/on on your phone. 2) Open/close the hearing aid battery door or place them in the charger briefly. 3) Delete the device from Bluetooth settings and re-pair. 4) Restart both devices.

Troubleshooting
πŸ”Š

Audio Delay / Latency

MFi and ASHA protocols provide low-latency streaming (under 50ms). If you notice audio delay when watching video, ensure your hearing aids are certified for your device type. Standard Bluetooth can have 150–200ms delay.

Performance
πŸ“Ά

Optimize Streaming Range

Stay within 30 feet of your connected device for stable streaming. Walls, microwaves, and other wireless devices can cause interference. If signal drops, move closer to your device or disable nearby Bluetooth devices.

Hearing Aid Maintenance Routine

A consistent maintenance routine protects your investment and ensures optimal sound quality every day.

πŸŒ…

Morning Routine

Wipe hearing aids with a soft, dry cloth before inserting. Check for wax buildup on speaker/receiver. Insert fresh batteries if needed and ensure battery door clicks fully closed.

πŸŒ™

Evening Routine

Remove hearing aids and wipe down with a dry cloth. Open battery door or place in charger. Use a wax pick/loop to gently remove any visible ear wax from the speaker port. Store in a dehumidifier case.

πŸ“…

Weekly Deep Clean

Use a hearing aid cleaning kit (brush, pick, wax loop). Clean all ports, microphone openings, and tubing. Replace wax filters/guards if blocked. Inspect tubing for cracks or discoloration.

🚫

What to Avoid

Never use water, alcohol, or cleaning sprays directly on hearing aids. Remove them before showering, swimming, or applying hairspray/sunscreen. Avoid dropping on hard surfaces and keep away from pets.

FAQ

Frequently Asked Questions

Answers to the most common battery and Bluetooth questions from our patients.

Disposable zinc-air batteries typically last 3–10 days depending on battery size, usage hours per day, and how much Bluetooth streaming you do. Size 10 lasts 3–5 days, Size 312 lasts 5–7 days, Size 13 lasts 7–10 days, and Size 675 lasts 9–20 days. Rechargeable lithium-ion batteries typically provide 16–24 hours per charge, with some premium models reaching 30+ hours.
For most modern hearing aids: 1) Turn off your hearing aids, then turn them back on to put them in pairing mode. 2) On your phone, go to Settings β†’ Bluetooth and enable Bluetooth. 3) Your hearing aids should appear in the device list β€” tap to pair. For iPhone users with MFi-certified aids, go to Settings β†’ Accessibility β†’ Hearing Devices for the best experience.
Bluetooth streaming requires significantly more power than standard hearing aid operation. Streaming audio can reduce battery life by 30–50% compared to non-streaming use. To extend battery life during streaming, limit streaming sessions, lower the streaming volume, and ensure your hearing aids are fully charged or have fresh batteries before extended streaming periods.
Store zinc-air batteries at room temperature (around 68Β°F/20Β°C) in a dry location away from direct sunlight. Do not store in the refrigerator as condensation can damage them. Keep batteries in their original packaging until use, and remove the pull tab only when ready to insert. Properly stored batteries maintain their charge for 2–3 years.
Yes β€” rechargeable hearing aids are excellent for travel. Most modern models provide 16–24 hours per charge, covering a full day including streaming. Always pack your charger, and consider a portable charging case for extended trips. Many models support quick-charge, giving several hours of use from just 30 minutes of charging.
Common fixes: 1) Turn Bluetooth off and back on your phone. 2) Open and close the battery door on your hearing aids or briefly place rechargeable models in the charger. 3) Delete the hearing aids from your phone's Bluetooth device list and re-pair from scratch. 4) Ensure your hearing aid firmware is up to date via the manufacturer's app. If problems persist, contact us for a free remote troubleshooting session.
