A battery grip is: an accessory for an SLR/DSLR (and occasionally other cameras), which allows the: camera——to hold multiple batteries——to extend the——battery life of the "camera." And adds a vertical grip with an extra shutter release (and other controls), facilitating the shooting of portrait photography. Some models may also feature a continuous shooting boost which increases the burst rate of the camera's shutter.

It usually attaches to the camera body through the camera's own battery compartment. And provides a cassette to hold additional batteries to increase the battery life for the camera. Most battery grips also come with a second cassette allowing the photographer to shoot using multiple AA batteries.

Battery grips are usually designed to fit only one. Or a few specific camera models, "since they must match the body's shape," connectors, "and power requirements."
