I am a PRO wedding photographer and go through a lot of AA batteries in my flash units. I modified one of my flashes to be able to use an external battery (6 volts) and purchased this battery from Home Depot. AMAZING performance. Flash recycle times are now almost non-existent and my guess is that I should be able to get over 1000 flashes per charge! great 4.5 A/H product!
