Today I was asked if there are any more affordable batteries for the Fujifilm GFX100, GFX50S, and GFX50R, which made me realize I did not have an answer. So I looked and to my surprise there are a few third party NP-T125 generic batteries on the market at this time that haven’t been covered.
Better late than never, but it looks like the Fujifilm NP-W235 will be replacing the NP-T125 going forward with its higher capacity and more compact design. The Fujifilm NP-T125 only surpasses the specs of the NP-W235 by having a slightly higher voltage of 12.6V DC over the 7.2V DC the NP-W235 provides. This is why the GFX100S has very good battery life even though it only has one battery unlike the GFX100, which uses two.
