Don't be fooled by the hype
on September 22, 2016
The batteries work fine initially, (although read at 100% for too long and then rapidly decline, overall life appeared to be normal) but then after 5-10 charge cycles, they are clearly showing their true colors.
I bought four of these, and all show the same characteristics. After several cycles of use, overall life declines greatly, as does dependability. Battery life percentage as seen from the camera will roll up and down, depending on the load on the batteries (50% one minute, then 70%, then 30%, then back to 50%). This happens on both my a6000 and a7ii.
Also, and most importantly, related to the previous issue, they will sometimes deplete unexpectedly. If you're using these batteries, you can't let them go below 30% charge, or they might die suddenly. Not only do you risk missing a crucial shot, but having a battery die in the middle of a write to your memory card can result in a corrupted card, and lost photos.
Stock Sony batteries are vastly superior, even after 50+ charge cycles. I previously had bought some cheap Ezopower batteries for about the same price as these, (four of those as well), which are much better behaved. Their overall life has diminished more than the Sony batteries do, but they have never suffered from the charge state instability exhibited by the Wasabi batteries. Unfortunately Ezopower no longer appears to sell them.
