Cameron Sino Sony NP-BX1 accu (3.7 V, 950 mAh, Li-ion, huismerk)

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.

Size and performance are of great. My camera (sony rx100 m5) is the best

Its a great battery its the one Sony supplies with camera. Always buy batteries from a good dealer or shop , I have been caught out buying batteries with makers name on that are not genuine. they can fail and could cause damage to camera. So buy Genuine batteries from a good retailer.
