How often should the batteries be charged?

The batteries should be fully charged every night. Once the hearing aids are finished charging, the indicator lights turn from blinking green to solid green. A full charge may take up to 7 hours – the charge time varies based on how much the battery was depleted during the day. Do not try to extend battery life by charging every other day, as this increases the chances of depleting the battery. A fully depleted battery will take longer to charge and may not fully charge in time for next use.

What happens when the silver- zinc rechargeable battery is getting low on power?

The hearing aid wearer will hear the low battery warning. Once the low-battery warning occurs or once a hearing aid shuts off due to a low battery condition, the battery door should not be opened and closed to reboot the hearing aid. Rebooting after the low battery warning can override the smart circuitry in the battery door into believing it has a traditional disposable battery installed and, although the hearing aid will continue to work for a short period, it may over-discharge the battery. If a low-battery warning from the hearing aids is received, the hearing aids should be placed in the charging base for charging or the batteries should be replaced with non-rechargeable batteries. The rechargeable batteries should not be stored with metal objects such as keys or coins.

What happens if the hearing aid wearer forgets to charge the battery at night?

They can use a disposable zinc-air battery until it is convenient to re-charge the batteries – ideally the rechargeable batteries should be charged the next night. The rechargeable silver-zinc batteries are a gold color, so they will not be mixed up with zinc-air disposable batteries. The rechargeable batteries should be stored in a safe place and should not be stored with metal objects such as keys or coins.
