Is it possible for you to test your new batteries?
They may be just crap or your charger is. Or you have let them discharge themself for some weeks. Self-discharge is a serious problem for NiMh based on pre-LSD-technology.
Personally I stand away from all AA over 2400 mAh (degration too high over time) and only use those produced by a "respected" manufacturer. Most companies doesn't have a production line of their own. They just purchase them and put their label on.
I had quite a good time with "old-fashioned" NiMh by GP (2000-2400 mAh) but going to use LSD-type (Low-Self-Discharge -> "Eneloop") which I can recommend.
Your flash output number is much too low!
EDIT: Another point comes to mind. I never had an issue with that but it may be worth a try. Some batteries have to be charged und discharged several times to reach their nominal capacity. Not my opinion, that's what some sources say.
EDIT: Just tried to shot with 2100 mAh fresh from the charger. Used 21 shots and recharge time at manual full power dropped from about 9 during first shots to 10 seconds. Much energy left, I suppose.
