Got an aftermarket battery from Vidpro via Amazon:
Battery looks like an exact replica of the OEM battery without the Fuji Logo.
Has the insertion direction arrow on the battery body. Functions no differently than the OEM battery. Fits perfectly.
The battery comes in a blister pack and has a Power2000 brand label.
If you are looking for spare batteries this may be the battery you are looking for.
This one was a bust:
Got this as it was listed as compatible with the Fujifilm Xpro-1 Camera NP-W126 battery.
Have tired multiple times to charge the battery. The charger blinking green light (indicates error) comes on after ~5 minutes on the charger.
Battery does not hold a charge.
Sellers return policy has enough caveats that I'm thinking it will cost even more to try and return this. Shipping to/from is buyers responsibility.
Restocking charges may be involved.
If you are looking for an aftermarket battery for the Xpro-1 this is not the one you are looking for.
