Have 2 batteries ordered because I have two cordless Medion device. Basically, the batteries fit well as Eratz for orginalen batteries in the Medion devices. However, after half a year the life left on both devices or batteries already so much after that they were no longer usable. I always spend the night with Akuus that wherever possible they are only discharged before they come back to the station. But even this approach fühte to rapid degradation of the battery. Monday device can also be ruled out since two batteries were ordered. Therefore recommended ncht in my view. I now times try NEN other manufacturers.
