I haven't counted how many shots, but it's significantly longer and less erratic than the rechargeables I used, even after leaving the flash on by mistake for half an hour. Mind you, I'm not sure the rechargeables were a reputable brand, so they could have been cr*p to start with.
I can't explain why changing the flash batteries makes the difference. I'm guessing it's something to do with the flash having enough power to read the voltage from the trigger. I'm not big on physics, but perhaps the trigger's output range is very narrow, which is why they have a reputation for "failing".
[In other words, the trigger might be firing, but its output is not powerful enough for a flash to pick up unless the batteries are at peak power - just a theory!]
