Smarty Pets Battery 2 Pack for Model U4 Automatic Pet Door Collar

Description

The Premier Pet™ 6V Lithium Batteries are the replacement batteries for your Premier Pet Fence receiver collar. The battery module easily installs into the collar's battery compartment by using a flat edge, such as the test light tool included with the collar or a coin, to twist and lock it into place. Each replacement battery should last from one to three months. Replace whenever you see the low-battery indicator flashing on your collar to ensure your pet stays safely contained within his/her boundary.
