The bag is really great. My Sony alpha 58 fits perfectly into it with an additional lens. Everything is safely stored and well padded. The extra pockets on the sides are more than enough to stow all the accessories. The material makes a high quality impression and was processed very solid. Very useful, I find that you do not always have to open the clip seal to take out the camera. One can take out the camera by simply opening the upper zipper. How fit the bag in wet water will only make out yet.
Battery I can not say much. It fits into the charger and can be loaded. Duration etc, I have yet to examine in more detail in the endurance test.
