In a nutshell: Rechargeable hearing aids run for up to 20 hours on a single charge, and up to 16 hours with extensive streaming. A full charge takes around 3 hours. The permanently installed battery loses capacity over time, with the first noticeable losses usually appearing after 4 to 5 years, but they generally still last all day. The battery can only be replaced by an audiologist. For more flexibility in the office and while traveling, a second charger is the easiest solution.
Runtime and Charging Time in Daily Life
Without streaming, a single charge can last up to 20 hours, easily getting you through the longest day. If you stream a lot via Bluetooth (phone calls, TV, music), you can expect up to 16 hours, depending on usage. After about 3 hours in the charging station, the devices are fully charged again. Practical tip: Many chargers provide enough charge for several hours in just 30 minutes. The tried-and-true evening routine: first 45 minutes in the PerfectDry Lux for drying, then into the charging station for the night.
When the Battery Weakens
Like any lithium battery, the one in your hearing aid also loses capacity over time. The first noticeable capacity losses usually appear after 4 to 5 years. Typically, the runtime will still be sufficient for the entire day. The battery is permanently installed and can only be replaced by an audiologist, who will arrange for the replacement at the factory, even before any noticeable decline, if desired. Please do not attempt to work on the device yourself. Before replacing, a quick check is worthwhile: Is the device charging correctly at all? Place it in the charging station for 10 minutes and check the charging indicator; sometimes it's due to dirty charging contacts or the station itself. The guide Battery or Rechargeable clarifies whether a rechargeable battery or a disposable battery is better for you.
The Underestimated Helper: The Second Charger
Many of our customers solve this problem very practically: a second charger for the office, a second home, or as a backup. The mobile Go models with a built-in battery can also charge on the go without a power outlet, ideal for travel. Important: Charging stations are platform-specific; the compatibility table on each product page shows you the suitable models.
Frequently Asked Questions
Should I charge the devices every night? Yes, that is the intended rhythm. Modern charging electronics prevent overcharging. Ideal in combination with the 45-minute drying beforehand.
My devices no longer last a full day. Is the battery defective? After 4 to 5 years, a loss of capacity is normal. If the runtime is no longer sufficient for the day, the audiologist will arrange for a battery replacement at the factory. For newer devices, first check the charging station, contacts, and streaming behavior.
What happens if the battery runs out while I'm out and about? With a mobile Go charger, you can recharge without a power outlet; 30 minutes are enough for several hours of hearing time.
