Photographers will tell you that using rechargeable batteries are the way to go when it comes to using flash/speedlights. They charge up much quicker than Alkaline and they either work or do not. Alkaline charges you flash at a slower rate and will give you weaker inconsistent power when they are dying (rechargeable give you all they can or just die out).
