If your hearing aid charger is not working properly, it can be hard to tell whether the problem is the charger, the hearing aids, or a weakening battery. Rechargeable hearing aids can develop charging issues over time, including reduced battery life, blinking warning lights, or failure to charge as expected.
This guide explains how to diagnose common hearing aid charging problems and what to check before replacing a charger or seeking service. If you need a replacement, you can browse our hearing aid chargers here.
Common Signs of Battery Problems:
Lithium-ion hearing aid batteries begin to show signs of aging after about three years. If your hearing aids are not holding a charge as long as they used to or the charger is blinking red when trying to charge them, this could be a sign that the battery is weakening.
How to Tell If It’s the Hearing Aid or Charger
A simple way to determine the root of the issue is by switching the hearing aids from side to side in the charger:
- If only one side is blinking red: Swap the hearing aid on the red-blinking side to the other charging port.
- If the red light follows the hearing aid, it’s likely the hearing aid battery is at fault.
- If the red light stays on the same side, the problem may be with the charger.
What to Do If It’s the Hearing Aid Battery
If the issue lies with the hearing aid battery, don’t worry—lithium-ion batteries can be replaced. Hearing aids out of warranty?

What to Do If It’s the Charger
If you’ve determined the issue lies with the charger, there are a few steps you can take before replacing it. Sometimes, the problem could be as simple as a faulty charging cable. Here’s what to try:
- Check the Cable:
The charging cable can sometimes wear out or malfunction. Try using a different cable compatible with your charger and see if the issue persists. - Inspect the Charger Ports:
Ensure that the charging ports are clean and free from debris. Sometimes dust or lint can interfere with proper contact between the charger and hearing aids. - Replace the Charger:
If switching the cable doesn’t resolve the issue and the charger still isn’t working, it might be time for a replacement. At Hears Hearing & Hearables, we sell all brands and types of hearing aid chargers and can help you find the right one for your specific hearing aid model.
