Perimeter Technologies/Pet Stop’s batteries are innovative little marvels of technology that work flawlessly with the receiver collar. They’re ranked the highest on the market in durability and performance, and relatively inexpensive when evaluated next to batteries from companies such as Invisible Fence ®, DogWatch ®, PetSafe ® and the rest.
Note: A compatible battery other than Perimeter Technologies/Pet Stop's may be substituted.
