Sony NP-BX1

Solid product. A definite must for an RXM, in which these batteries do not last that long. Note that non-original versions of these batteries are frequently only around % of the capacity of these originals

Stick to oroginal batteries if you love your camera. Ive lost a couple of great cameras to 3rd party batteries. Yes original is always expensive, but not as expensive as your camera on the whole.

Bought this spare battery for my SONY ZV-1 because one battery won't be able to survive a day trip. People who want to shoot long videos probably need to get a few more.

Mt camera battery failed and I needed a replacement quickly - not a regular item, but John Lewis had in stck and delivered quickly.

This is just a regular, battery nothing special.(I use it when the other one runs out to maximise the time I get using my camera.
