tested and ready to review
on April 5, 2014
After I received these I ran them through the tests to make sure first off they worked and second if they stood up to the regular SONY batteries I use for my Fotodiox lights. When you first open the packaging of these Maximalpower batteries, there is a small font section on the packaging that says you have to charge full, kill full 3-5 times for maximum efficiency. So I did this.
I ran it dead, I charged it full, I ran it dead, and charged it full - 5 times through this cycle. I have two Fotodiox lights starting at the same time on full power - just how I would be using them in the field. The regular batteries last almost 2 1/2 hours, the Maximalpower batteries last about 1 1/2 hours. While these will be fine for back ups to get those final few moments - it's pretty saddening considering the reviews on here talking them up so much.
I did this test with 2 separate Maximalpower batteries and 2 sony batteries. Again, can't complain since they are so much cheaper, but a good note to know in the field. Hope this helps
