Need help with X-T2 batteries

I just picked up a really nice condition X-T2 as my back-up/second camera. The camera is in very nice shape and it really takes some nice photos.

But- it's old and so is the original battery. I'm hoping people can help me out by recommending 3rd party battery options for this camera. I'd like to hear the good and the bad about the batteries that are out there these days.

Thanks in advance!
