Great batteries - I use these batteries in my SB800 Nikon and they are fantastic. Of all the batteries I ve tried, these have given the fastest recycle times and the longest life. I m not sure why other people are having problems - maybe they don t give the batteries chance to complete the re-charging times. I ve had mine for 6 months and approximately 50 recharge cycles and they are still great.
Ok...but don t really hold too much charge - Well these batteries are ok for the price (I think they were around $6+shipping when I bought them). But they do not really hold as well as a 2900 mAh should....I get about the same charge as I do from a 2500mAh on my Canon S5 (around 100-150 shots w/Flash). But if you are looking for some cheap batteries that work, I guess this is the option for you.
Worst batteries ever! - These batteries are incredibly bad. I bought them for my Nikon Sb-800 speedlight. Since they are 2900 mAh, I thought I was going to get outstanding results. I did not.I ve used Impact 2900 mAh, Enegizer 2500 mAh, and several other 2700 mAh AA batteries. Results were fine. But thses Power 2000 batteries died almost immediately. I couldn t believe it was the batteries because it was so quick. I thought my SB-800 went bad. But, I replaced the batteries and sure enough, all was well.Don t buy Power 2000 batteries. They are very bad.
