A pack of 8 x lithium CR123 photo batteries for Arlo wire-free HD security cameras. We recommend Panasonic, with their huge experience in the photographic and camera industry and also because they are the largest producer of this particular battery in the World. They even manufacture this battery for some other very well known brand names. So going direct to the largest producer allows us to sell these Arlo HD camera batteries at very sensible prices without compromising on quality. Get solid reliable performance at a fraction of high street prices. Why not take the opportunity to stock up, the more you buy the cheaper they get. Just click on the product to see the price breaks we can offer. This pack of 8 is perfect if you have a two camera system (VMS3230). Camera not included.
