Fujifilm NP-W235 Rechargeable Battery

I was skeptical about the in-camera charging, but it works perfectly with my X-T4 and the battery holds up through a long afternoon of shooting. The twin charger also tops it off in a reasonable time when I need a quick second slot ready.

This battery lasts me an entire day of shooting my X-T4 without needing the second one. The lithium-ion holds its charge really well even when sitting in my bag for weeks between shoots.

I've been using this as my backup battery for the X-T4 and it holds a charge just as well as the original that came with the camera. It's nice that I can pop it into the Twin Battery Charger without any issues. Makes a long day of shooting much less stressful.
