Cheap and name you can trust,

This review is from: Energizer FLNP50 Digital Camera Battery Equivalent to Fuji NP-50, Pentax D-Li68, Kodak KLIC-7004 Battery (Accessory)
Perfect extra battery for the Fuji X10 (a must have), cheap, no probs with using the Fuji charger, displays power-level accurately in the camera.
Only thing is, it doesn't come with a plastic case so I worry about it shorting or whatever - All my other cameras have warned about carrying a battery out-of-camera 'naked'. So with a case it'd have got 5*.
