Anonymous2 years ago000After 2.5 years, both batteries have inflated at the same time. Which replacement battery should I order or does the complete set have to be replaced? Show in original language (German)Anonymous2 years ago011Hoi - there are 2 different replacement batteries for the 6500D (from Nenoate itself) https://neonatebabymonitor.com/product... and https://neonatebabymonitor.com/product...The best thing is to contact the customer service quickly to see if they can clarify this and procure (and if necessary know where to exchange). https://helpcenter.digitec.ch/hc...
