The Mamiya site listed two two chargers which featured the capacity to charge two LEAF batteries simultaneously; one was designed with the charging wells situated side by side, the other looked like the wells were one below the other.
I think that side by side may have the benefit of being able to later accept batteries with greater capacity, that are deeper. Which is to be preferred?
Hi Jerry, if you follow the link I've posted and click on the "Leaf Aptus-II" tab (see attached screen grab) you will see the only dual charger that we sell. It takes any size battery and has a replaceable insert for other videocam batteries (e.g. Cred/ IQ).
It also comes with a car 12V plug+cable
