[NSRCA-discussion] Chargers??? 2007

[Anthony Romano]

Hi Ken,
Had the same situation with any Nimh reciever pack. Short cycles with any 
charge rate above 300mah on both my Sirius Supernova and a little Diamond 
charger. Gave up and just remember to charge when I leave the field and when 
I get home. Never had issues with Nicads. I am assuming the smaller peak 
inherent to NIMH is fooling the chargers.
