Client Critiques
I purchased this battery based on extremely fine critiques on other Opteka merchandise on Amazon.com. I also have put to use third party batteries on my cameras with quite really good performance. Nevertheless as other individuals have stated it doesn't perform in the Sony A55 with out some assist.
Many state that it is as well brief but I've measured each this and the original Sony battery but located no distinction in length. It is simple to consider it is as well short because if you push on it or place a piece of thick paper amongst it and the battery door it will perform. What I did locate is the compact raised section where the contacts are mounted seem to be a bit longer than the Sony battery. How this reduces the capability to make get in touch with I don't know.
When I first had the battery it charged in the Sony charger and nonetheless does. Nevertheless it also worked in the camera the initially time. After that it would not perform unless I put some tape on the bottom so the battery door would push it into the contacts. I ended up making use of it as a backup battery only for the reason that I was afraid it would ruin the battery door. I've subsequently purchased another Sony battery and will leave this one in the drawer.
This appears to be a superior product for now. Charged up effectively to 96% in 1.five hrs. I have not implemented it significantly, but can say it will last as significantly as OEM battery. The only problem, which can be regarded substantial, is that it is shorter than the original Sony battery. So you want to push it in effectively in the charger to get it charging. Also you will need to keep a little piece of thick paper in between the battery and the battery lid in the camera.
Properly, it works for me. But i would count on them to fix this situation.
