Can only chime in with Wasabi and Smallrig as those are the only 3rd party batteries I've owned for my Fuji bodies. As with most of my experience with non-OEM batteries, they work, but I find the charge runs out a little earlier than an OEM battery (no scientific testing though). But the cost is much lower that it doesn't matter to me if they don't last as long per charge.
Quick look at Amazon US shows three cheaper alternatives: K&F Concept, Wasabi Power, and Smallrig (in orange and baby-blue). There are other, less known brands.
Which brand is good, which one to avoid?
