Leading Brand Rechargeable Hearing Aids

No more fiddling with batteries!

Rechargeable hearing aids have been around for many years, with leading German company ‘Siemens Hearing Instruments‘ paving the way with behind-ear models, and Hansaton (another German company) being the only brand to have released in-ear rechargeable hearing aids. (Note: ‘Siemens Hearing’ is now ‘SIGNIA’ which is owned by Sivantos).

These hearing aids used batteries that reduced hearing aid performance over increasing periods of charge cycles and thus never really developed that far. However, developments in alternative battery technology has progressed and all leading hearing aid manufacturers are now offering high specification rechargeable hearing aids – with new custom in-ear rechargeable hearing aids launched by Starkey in 2020.

Lithium-Ion

Lithium-ion battery technology is creeping into all gadgets – and hearing aids are no exception. Why? – because lithium-ion batteries charge quicker, last longer on a charge, they do not deteriorate from partial charging (after a first full charge) and the batteries do not degrade in performance over time (although the charge capacity will drop over time). The main consequence being that lithium-ion is volatile and therefore is more hazardous and requires more care in development. (Note: If posting lithium-ion rechargeable hearing aids you should attach a hazardous substance sticker which is supplied at the post office).

Lithium-ion batteries are integrated into the hearing aid – the user cannot change the battery.

Lithium-ion rechargeable hearing aids were originally bigger than silver-zinc hearing aids, until the introduction of the slim-line Signia Styletto. Lithium-ion rechargeable hearing aids will inevitably become smaller.

Widex ‘Moment’ : lithium-ion

Widex launched their first lithium-ion rechargeable hearing aid in 2020 during the storm of Covid and hence didn’t see the take off that they’d hoped for. That said – Widex Moment is a supremely good hearing aid offering many features.

16-20 hours of listening (depending on streaming time with full 4 hour charge).

30 minute fast charge for 4 hours listening

Drop-in lightweight charging case

Widex now offer two chargers – a charge and clean (meaning dehumidifying action) charger and a simpler drop-in charger. The ‘charge n clean’ is extra cost and not cheap! Contact us to discuss pricing.

A look to the future

The inventor of lithium ion battery technology – Mr John Goodenough.

Developments are being made for higher capacity, increased longevity and quicker charging batteries, which will in turn find their way into the hearing aid market and will allow for smaller rechargeable hearing aids.

We hope to see real developments coming from thermal batteries – whereby the hearing aids can run on the heat of our body!
