The Browning Trail Camera External Battery Pack extends run time on any Browning trail camera by adding a second tray of 8 AA batteries external to the camera body. The pack uses the same easy-to-use battery tray design found in the cameras, so swapping cells in the field is quick. A built-in battery tester lets you verify cell strength before you leave the camera in place, and a twist-lock plug keeps the power cord positively connected to the camera so a curious animal or a branch in the wind will not pop the plug loose.

Weatherproof housing and a tree-ready shape make this a reliable way to stretch intervals between camera checks during long summer or deep winter sets. Batteries are not included.
