How Do You Check the Battery in an Invisible Fence® Brand Collar?

Your pet's Computer Collar® Receiver depends entirely on a working Power Cap® Battery to function. If you're wondering whether the battery in your dog's collar is still good, or how to check it, here's what you need to know.

Watch for the Red Blinking Light

The simplest indicator that your Invisible Fence® Brand collar battery needs attention is a red blinking light on the Computer Collar® Receiver unit. If you notice this light, your Power Cap® Battery is running low and should be replaced as soon as possible.

Don't wait until the battery dies completely. A weakened battery may cause inconsistent performance before it fails entirely, which means your pet's boundary may not be fully reliable.

Don't Wait for a Warning

Invisible Fence® Brand recommends replacing the Power Cap® Battery every three months regardless of whether the red light has appeared. This proactive approach is the safest and most reliable way to ensure your pet's collar is always functioning at full strength.

Batteries last approximately 90 to 120 days under normal use, so a three-month replacement schedule keeps you comfortably ahead of any potential issues.

How to Replace the Power Cap® Battery

Replacing the battery is a straightforward process.

1. Use a small, thin coin inserted into the slot on top of the Power Cap®
2. Turn the coin 45 degrees counterclockwise
3. The spring inside will push the battery out of the collar unit
4. Line up the lugs on the bottom of the new Power Cap® Battery with the grooves in the battery chamber
5. Gently turn the new battery clockwise 45 degrees until it is secure

Always use a genuine Invisible Fence® Brand Power Cap® Battery. Third-party batteries may not fit correctly and can allow water into the collar unit, putting both the equipment, warranty, and your pet at risk.
