Ok this was a very informal test, I got 4 radio shack 1600 mha nimh AA batteries and brand new kodak photolife batteries, put them in the AF330 and tried it, recharge time was 5-6 sec and I fired 200 test shots with no drop in recharge time at full power ( MH manual mode ) then put the photo life batteries and did it again, the photo life batteries did last for more shots but after 50 the recharge times started to get longer and by 200 it would take 20 sec. The cheap radio shak rechargeables were then placed into my achiever flash and would charge it in 6-7 sec ( this is AFTER 200 shots in the AF330 ) and lasted another 50 shots but unlike alkalines they just die with no warning. I think no more alkalines in my flashes any more and with a 1 hr car charger I can make it through a few rolls of film a night easily.
