DIY Phonak Lumity L90 Rechargeable Battery Replacement – Planning Ahead

Hi everyone,

I’m considering buying a pair of Phonak Lumity L90 hearing aids from eBay and I’m trying to plan ahead for when the rechargeable batteries eventually need to be replaced.

For those of you who and have repaired or serviced your own Phonak hearing aids, I’m curious about your experience with battery replacement.

Have you replaced the rechargeable batteries yourself?

If you decided not to do it yourself, did you use a Phonak provider or an independent/online hearing-aid repair shop?

Approximately how much did the battery replacement cost?

I’m not looking to replace the batteries right away — I’m just trying to understand the future repair options and potential cost before purchasing the L90s.

Thanks in advance for any DIY experiences or advice!

Someone on here tried to replace the batteries themselves a year or two ago. It is difficult to find the exact battery and also very difficult to perform the replacement as it is not designed to do so. Just opening the case is difficult since it is IP68 sealed.

My experience with having this done under warranty with Phonak is that they just replace the entire .

As it happens I asked my Audi what the cost was to send my Paradise HAs to Phonak for replacement. It was $600 per device. We both agreed that $1200 was too much for a 5+ year old HAs. I am sure that someone here will know of a cheaper service though.

Search for “battery replacement” and you will see several threads that go into the intricacies

Thanks for the reply, I’m looking at buying one right now but Im worried about the battery going bad a year or 2 from now. $600 per device seems a bit high to have the battery issue fix. I’ll wait and see if somebody have experience sending them to an online hearing aid repair and how much its cost. Thanks!
