Charging tips
You may have some questions on how to best charge
your hearing aids. Read the questions and answers
below. If you have more questions, your Hearing Care
Professional will help you.
"
How often do I need to charge the hearing aids?
We recommend charging the hearing aids daily, even
if the power cell is not empty. Charge them overnight
so you can be sure to start your day with fully-charged
hearing aids.
"
How long does charging take?
A full charging cycle takes approximately 4 hours
(+/- 10 mins).
After 30 minutes, it is possible to use your hearing aids
for up to 6 hours.
Charging times may vary due to the use of the hearing
aids and the age of the power cell.
"
Can I leave the hearing aids in the charger?
Even when fully charged, you can leave the hearing aids
in the charger with the lid closed. They automatically stop
charging when they are fully charged.

2726
"
What happens if I forgot to charge?
Your hearing aids will automatically switch-off when the
power cell is empty. Charge the hearing aids as soon as
possible.
Hearing aids which have not been charged for over
6 months may be damaged due to an unrecoverable
deep-discharge of the power cell. Deep-discharged
power cells cannot be charged anymore and have to be
replaced.
"
What if I intend not to use the hearing aids for
several days or longer?
■Short-term storage (up to several days): Turn off your
hearing aids via the push button or place them in the
powered charger with the lid closed.
The charger must be connected to the power supply. If
the charger is not connected to power supply and you
place your hearing aids in the charger, the hearing aids
are not turned off.
Note that when you turn off the hearing aids via a
remote control or smartphone app, the hearing
aids are not turned off completely. They are in
standby-mode and still draw some power.

2928
■Long-term storage (weeks, months, ...): First, fully
charge your hearing aids. Turn them off via the
push button before storing them. We recommend to
use drying products while storing the hearing aids.
At 6 month intervals you will have to charge
the hearing aids to avoid an unrecoverable
deep-discharge of the power cell. Deep-discharged
power cells cannot be charged anymore and they
have to be replaced. We recommend recharging more
frequently than 6 months intervals.
Observe the storage conditions in hearing aids’ user
guide.
Ask your Hearing Care Professional for recommended
drying products.
"
What should I pay attention to when charging?
The hearing aids and charger must be clean and
dry. Observe the operation conditions in section
“Operating, transport, and storage conditions”. Avoid
charging at high ambient temperatures, as this can
shorten the life span and capacity of the power cell.
If you use the charger in a very warm environment, note
that it will stop charging and indicate error if the charger’s
temperature exceeds 45°C (113°F). Charging resumes
automatically after the device has cooled down. Do not
touch the hearing aids, they may be hot.
