Changing the Power Cap® Battery

Remove the old Power Cap® Battery:

  • Use the collar's buckle or insert a coin in the slot on top of the battery and turn it 45 degrees counter-clockwise. Do not push down while turning.
  • The Power Cap Battery will rotate while the spring inside will push the battery out of the MicroLite Computer Collar Unit’s battery chamber.

Install a new Power Cap® Battery:

  • Line up the lugs on the bottom of the battery with the grooves in the sides of the MicroLite Computer Collar Unit’s battery chamber. Make sure the metal tabs on the bottom of the battery are not bent.

  • Place the battery into the chamber while gently, but firmly, turning it clockwise 45 degrees with your fingers.

  • Use the collar's buckle or a small, thin coin to turn the battery clockwise until the slot on the top of the battery is lined up with the two small raised tabs on the bottom of the Computer Collar Unit. Do not overtighten by turning the slot past the tabs.

On average, the Power Cap® Battery should be changed every 3 months. Low temperatures, the number of times the pet challenges the pet containment system boundary, and improper collar fit can all reduce Power Cap® Battery life.

WARNING: The use of any power source other than an Invisible Fence® Brand Power Cap Battery may cause a Computer Collar Unit to operate erratically or fail. The use of unnecessary force may damage the case and render the Power Cap Battery inoperable. NEVER open a Power Cap Battery, dispose of it in fire, recharge it, expose it to heat above 212°F (100°C), or expose its contents to water. Doing so can cause leakage or explosion and may lead to personal injury.
