BTE battery-compartment (Nucleus CP800 series)

"battery cover"

This is the battery-compartment that houses 2 disposable batteries (Zinc/Air 675).  Batteries and/or batteryholder have to be purchased separately !!   Two disposable batteries deliver less power than a rechargeable battery.  Therefore this may be insufficient for daily use with your programs.  You should contact your CI-fitting centre before purchasing the Mini version !!
