Query: Dead On the Job

I do like the fact that I can use the batteries right away without a charge. Unfortunately when used in my flash head, I couldn't get passed 60 shots before I had to change them. The recycling time got considerably longer after the 45 shot. On the average I can take 150 pictures and I'm able to use 1 set of batteries. These just did not last for me. It's even worse when you take rapid shots. You may get the first one but the 2nd and 3rd, no flash. To be fair, if you can wait 10seconds between your shots, these are the batteries. If you need rapid recycling,these will not help
