need to confirm charging correctly

Yeah this sounds stupid but I just picked up a new radient ascend charger and 2 nimh 3300 8 cells. Please confirm that I'm hitting all the settings correct. 1) set to nimh. 2)set ma to 3300. confirm . It begins to charge and takes about an hour. charger gets warm. Is this all normal. I had one charger go up in smoke!Also, why would a battery charge say complete at 850 ma and in only 15 to 16 minutes. I just want to confirm that what I'm doing is correct and I'm not missing something on a charge procedure. lol Thanks for your help

sometimes, you have to restart it when it gets "done" like that. sounds right though! what other settings are their on the charger? voltage?
