Rechargeable Hearing Aids

Rechargeable hearing aids have been around for over 10 years now, with Siemens Hearing paving the way with behind-ear models, and Hansaton being the only brand to have released in-ear rechargeable models.

Manufacturers haven’t really pushed rechargeable technology until quite recently, and in 2017 several more leading hearing aid manufacturers launched rechargeable hearing aid models.

Below we list the models currently available and welcome you to contact us to find out more, or book a free hearing test to see which may work best for you.

Where are we now? – Lithium-Ion v Silver-Zinc

There are two technologies available: lithium ion and silver-zinc.

Silver-zinc batteries have been around for a while with Siemens hearing aids (now Signia). Whilst being very convenient, silver-zinc batteries only last about a year before they start to lose noticeable performance and then need replacing. Price can vary, but a pair of sliver-zinc batteries is likely to be about £30, compared to normal batteries costing £30-40 a year.

As of 2017 some hearing aid manufacturers have developed advanced lithium-ion rechargeable battery technology into their hearing aids. The key advantage being that they last longer before they start to degrade in performance (2 years) and they charge quicker.

There are a few downsides: some models can be quite large (update – see the amazingly thin Signia Styletto). Another drawback is that lithium-ion is a volatile product and has new postal delivery limitations and is more difficult to dispose of than silver-zinc batteries. Lithium-ion batteries are built into the casing of the hearing aids, so when they need replacing you have to send the aids back for replacement batteries. With silver-zinc batteries you can at least use normal batteries for emergencies.

Many key suppliers are now utilizing silver-zinc battery hearing aid technology because an independent manufacturer (Z-Power) has produced a battery charger that can be adapted to suit different models of hearing aid. This takes the development needs away from the hearing aid manufacturer – albeit the charges for z-power charging units are pretty expensive at about £300 – so going rechargeable is definitely not a cost saving exercise!

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.
