You all know that if you bring your Oticon hearing aid for a new battery to the audiologist, they charge you $150 and give it back in a week. Then when you look at potential retail places to replace your rechargeable batteries, there are not many options. I also found out that Z22A is compatible with part numbers with LIR840.
I found one on ebay that is a decent price.
