It appears to be the SAFT charger, which GNB batteries marketed under the SCR Flex name quite a long long time ago. SAFT is a Canadian company and the chargers were (and probably still are) made in Malaysia (I may or may not be correct about this).

I picked up some of their literature (under the V force name) and one of the claims is that the charger is more energy efficient because it uses a lower start rate! That's like taking a V-8 and only letting you use 4 cylinders for fuel economy (Hat tip to Chrysler.)

In terms of technology it represents an enormous step....backwards.

Crown is really sticking it to their salespeople with this one...there are more than a few sophisticated battery and charger companies that are going to eat them for lunch on this.
