Camera Pro - I don't think it was a voltage thing. Depending on the Dual chargers model and software revision it may or may not have been able to charge batteries. As stated earlier some chargers are just to old to charge all the new battery cell technologies. A Dual charger (not a Inter/Active 2000 series) would be to old to charge a Dionic. Production stopped onthat charger in 1996 five or 6 years prior to Dionics coming in otthe market.
If this is not the case, please contact our cuatomer service Dept at 800.541.1667. Your charger MIGHT just need a s/w upgrade $45 and will work just fine....Customer Serive will be able to tell you if this is the case.
