In the past decade or so, there has been some experimentation with rechargeable hearing aids. Most notably Siemens (now Signia) and GN Resound (who later stopped using these batteries). Siemens uses an older nickel-metal-hydride battery, which delivers about 8-10 hours use per charge. In 2017, everything started to change in regards to rechargeable hearing aids.
