A: I use it with a Nikon battery, it measures 1 1/4 X2 1/8 .The Velcro flap is a material that gives enough to put it on my camera strap if I don't want to carry in my pocket. So measure your battery and you will know real quick. Hope this helps.

Q: 4. Will this fit a Sony NP-FZ100 battery?

A: Sorry for the late answer. I use this for a Canon 7D battery and it wouldn't fit a battery much larger than that. If you can compare your battery measurements to a Canon 7D, maybe that would help. I think the holster was actually made for that particular battery or at least style of battery. You may want to check the company website "OP/TECH USA Battery Holster". Good Luck if you havent already solved the issue. Again, sorry for the late reply.
