Charger for 6 nmhd batteries for my Grundig Satellit 800?
 

I have not had success in searching for a battery charger that handles 6
nmhd batteries for my Grundig Satellit 800; it seems that they all handle
only 4 D nmhd's max. Which charger(s) and batteries do you use as part of a
strategy for the Satellit 800? Thanks
