The PT, you should be able to use that without any problems. There are thread adapters available from lots of places. Altsmoke is where I have gotten mine from. I have a 901 and a 510 and I interchange PTs,
batteries, and attys all the time using the adapters.
As far as the charger itself goes, I would think so - I'm not sure if there would be a problem with different batteries and rate of charge tho. Maybe someone else out there who is smarter than I am in such things would be able to help out on that one.
