Artman NP-W235 Rechargeable Battery(1-Pack) Li-ion Battery Compatible with Fujifilm X-T4 Camera, Fully Compatible with Original(2500mAh)

This took about 25 minutes to charge from empty to what it said was full, then lasted about 8 shots. Second charge took much longer and the battery is still going strong after 100+ shots.

Initially impressions are good for the money, the battery is a good fit, and the camera recognises it. I've only been through 3 complete power discharge cycles so far, 5 are needed for the battery to reach optimim capacity. It's currently not as good as a genuine battery, but seems to have around 70-80% of the capacity.The battery is offered with features, including overcharge protection, and cut out.I'll update the review in a few months, to report longer term usage. It's a third the price though, so some compromise is acceptable.

Seems pretty good to me lasts well

The battery life is quite poor. It drops literally few% every minute even without shooting.

decided to try this instead of official Fuji battery. Description was for Fuji XT4 which does have same battery as100S. Fits camera perfectly and although only recharged 3 times so far appears to be ok though may need more recharges to reach full capacity

Wanted a spare battery for my Fujifilm mirror less camera but grudged paying nearly £50 for the ‘real thing’ when past experience suggested more affordable options were perfectly acceptable. Right decision. The Artman unit is a solid piece of kit which charges quickly and seems to hold its charge as well as the battery which came with the camera. I have no hesitation in recommending it.

Does the job but doesn't show percentage charged in charger when charging another battery.

No difference to the original ones at a fraction price
