Query: NOT FOR SPEEDLITE EX FLASHES

DO NOT BUY THESE BATTERIES IF YOU'RE LOOKING FOR BATTERIES FOR YOUR FLASH UNIT.I bought these batteries to use for my New 430 Speedlite EX II. My fault for not reading that for EX speedlite flashes you want to use Alkaline batteries...But these batteries could definitely be better. Their discharge rate is very quick. You end up only using them for very light energy consuming items such as toys, remote controls or clocks... I would not recommend for cameras or other electronics that use a lot of power.For the 430 speedlite, I could only use the flash twice before I'd have to recharge again.
