Hi Gary, we're pretty cheap at
www.hearing-aid-batteries.org.uk, sometimes we're a bit cheaper with our listings on eBay or Amazon too so it's worth having a dig around. The going rate for good quality batteries on the net seems to be between £10 and £15 per 60, you can pay quite a lot more than that on the high street, maybe 3 or 4 times that. Personally I'd stick to the better quality branded batteries, no point in spending all that money on hearing aids and using poor quality batteries. We stock Rayovac, Duracell, Power One and Zenipower.
The Zenipowers have surprised me to be honest, they are a Chinese battery not too well known in the UK but very big worldwide. Our customers seem to really like them.
Hope this helps and it doesn't seem like an advertisement!
Regards
Paul
