Supernova 250s charger and ROV Batteries???

[5.0Trunk]

Ever since my Mag85 came together (FM 3H head and FM 9aa-d adapter)I have been using my Ray-O-Vac 1 hour charger with the ROV 1800 batteries that came with the charger to charge the batteries which takes some time. I can get a good deal on a SuperNova 250s for a good price and the question is will the supernova beable to charge the ROV batteries in the FM 9AA-D adapter? Also is the ROV 1HR charger any good? Thanks
