Important Notes and Recommendations for Charging
Lithium-Ion Batteries
Your hearing aids and your travel charger utilize lithium-ion charging
technology.
Your hearing aids:
We recommend charging the hearing instruments 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 instruments
If you do not intend to wear your hearing aids for a short period of time
(several days or weeks) we recommend you store your hearing aids in
either charger and keep it plugged into a power outlet. You may also turn
off your hearing aids via the rocker switch and store them safely.
If you do not intend to wear your hearing aids for a long period of time
(many weeks or months) we recommend you fully charge your hearing aids
and then turn them off via the rocker switch. You may then store them in
the standard charger that is not plugged into a power outlet, or in the travel
charger that has been fully charge and powered off by pressing and holding
the power button for 5-7 seconds until all lights turn off.
Important: We recommend you charge the hearing instruments every 3
months and you must charge them at least every 6 months. At 6 months
the hearing aids are at risk of having an unrecoverable deep-discharge of
the power cell. Deep-discharged power cells cannot be charged anymore
and they have to be replaced.
Your Travel Charger
It is important to regularly charge your travel charger. It is acceptable to
keep it continuously plugged into a power outlet. It is also safe to charge it
bi-weekly, weekly or monthly depending on how often you are charging your
hearing aids using the internal lithium-ion power cell. If you are not using
your travel charger as a charger you should charge it every 6 months. You
must charge it every 12 months to avoid having an unrecoverable deep-
discharge of the power cell. Deep-discharged power cells cannot be charged
anymore and they have to be replaced.
