I can't speak for MrV. Though, there is a DIY School Hearing Aids PDF document mamed (Buying Rechargeable Hearing Aids) that has a section named (Demant/Oticon). The oticon section has instructions for replacing Oticon rechargeable batteries, and also instructions for storing Hearing Aids with rechargeable batteries.
HMm; Maybe I should open a topic (for the Oticon section) here in this forum. I will come back and leave a link pointer if I do.
