Rechargeable pr48 (heating aid) battery charger?

waqasahmed

So 

I've got an NHS hearing aid, and the batteries last like a week or two if I'm lucky 

They've also given me a load of battery cells. I can "order" new batteries at any time by emailing them, but I don't like the idea of any kind of disposable battery. It's why everything that uses batteries in my house uses rechargeable ones.

Is there a way to charge the coin cell itself? And does anyone know where I could buy rechargeable coin cells too?

I found these online, although I am sure there are other suppliers. I don't know if they will fit your hearing aid or now though. https://www.hearingdirect.com/collections/rechargeable-hearing-aid-batteries

I have an NHS aid but it only takes the disposable ones not rechargeable

Primary cells still have the edge over rechargeable ones re. energy density. And as hearing aids are intentionally small, switching to rechargeable cells means a shorter battery life.
