These batteries are solid and work great in my Canon 580EXII. I carry a few set of them with me when I shoot weddings and they work awesome. They charge in about 90 minutes (with 90 min charger) and allow the flash to cycle quickly for continuous shooting.
I like Lenmar chargers and batteries. They work best in general use including electronic flashes.
5 batteries took a charge, 5 are no good. The 5 that took a charge lasted for 3 flashes on a canon speed light. I bought 10 Energizer batteries and have had no problems. Will never buy Lenmar batteries again!
