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’ now being ‘Sivantos’, and supplying SIGNIA branded hearing aids).

Hansaton have very little representation in the UK (Puretone Ltd being the UK distributor) and with talks of a Hansaton takeover we are unsure of their current position – we do not feel it is worth investing in such products for now. There are no other in-ear rechargeable options currently available.

Below we take a look at the latest behind-ear rechargeable hearing aids that can help you.

Firstly – Understand the battery types


Silver-zinc batteries have been around for many years. Siemens have offered rechargeable hearing aids for many years now. We are unclear as to why others did not follow suit earlier but maybe it is because silver-zinc batteries degrade slowly over time and therefore this reduces performance in the hearing aids. It is therefore slightly counter productive and should be borne in mind when purchasing your hearing aids.

In 2017 a company called Z-Power teamed up with several hearing aid manufacturers and produced a modular battery charging unit which can house different hearing aid charging trays – the manufacturers simply have to adapt the battery doors to fit into the trays. This meant that the suppliers had a rechargeable option, without having to put in much development time – and this started competition in the rechargeable market. All very good, but two problems: the charging units are expensive at around £300+; and the batteries still degrade over time. More information on ‘Z-Power


Lithium-ion battery technology is creeping into all gadgets – and hearing aids are no exception. Why? – because lithium-ion batteries charge quicker and do not degrade 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 therefore integrated into the hearing aid – the user cannot change of handle 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.

So – we recommend Lithium-Ion hearing aids

Recommended lithium-ion rechargeable hearing aids

Phonak : lithium-ion

Phonak entered the rechargeable hearing aid market in 2017 – and with the Audeo B-R (receiver-in-canal), Bolero B-PR and Naida-B-R (BTE models) have a good range to choose from.

ALSO NOW – Phonak Audeo Marvel – the first ‘made for android & iPhone‘ hearing aid

Signia : lithium-ion

Signia (formerly Siemens Hearing) introduced lithium-ion rechargeable battery technology in 2017 with the Signia Cellion hearing aids. The Cellion has now been replaced by the Signia Pure Charge & Go, and Signia have now introduced the amazingly thin and stylish Signia Styletto rechargeable hearing aid.

ReSound Quattro : lithium-ion

Not a moment had gone by after Sivantos launched the cosmetically appealing Signia Styletto that ReSound then launched the LiNX Quattro lithium-ion rechargeable hearing aid, which whilst not as slim, is as small in volume, but also offers the benefit of ‘made for iphone’ streaming and remote control technology (and Android remote control). So the LiNX Quattro is the first ‘all encompassing technology’ lithium-ion hearing aid.

Starkey Muse iQ-r : lithium-ion

Starkey’s first foray into the world of lithium-ion rechargeable hearing aids – the MUSE iQ-R (receiver-in-canal) hearing aid.

Unitron : silver-zinc

Unitron entered the lithium ion rechargeable hearing aid market in 2017 with the Unitron Tempus – the world’s smallest rechargeable (receiver-in-canal) hearing aid (at time of writing). A very nicely designed and highly technical rechargeable hearing aid option – utilising the Z-Power charging unit.

Starkey : silver-zinc

Starkey also entered the market of rechargeable hearing aids in 2017 utilising the Z-Power charging unit.

We recommend Starkey’s lithium-ion batteries as above.

Oticon : silver-zinc

Oticon OPN – the first rechargeable hearing aids offered by Oticon utlising the z-power charging unit.

Oticon OPN are high performance hearing aids offering ‘made for iphone technology’.

Resound Linx 3D rechargeable hearing aids

ReSound : silver-zinc

Resound Linx 3D rechargeable hearing aids were launched in 2018 and use the z-power charging unit.

The hearing aid casing is slightly different to the normal Linx 3D – thus, if you already have Linx 3D you cannot use the charging unit.

We recommend ReSound’s lithium-ion batteries as above.

Widex : silver-zinc

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.
