Tips for Maintaining a Strong Invisible Fence Collar Battery

Maintaining a solid collar battery is essential to ensure the efficiency of your invisible fence system. By following these tips, you can extend the life of the battery and enhance the overall performance of the collar:

Regular Cleaning:

Keep the collar clean by regularly wiping it down with a dry cloth. Dirt, debris, and moisture can interfere with the battery’s performance and cause corrosion. To provide consistent signals, clean the contact points as well.

Proper Storage:

 Keep a spare battery in a cool, dry place, away from direct sunlight and extreme temperatures. This will help preserve their capacity and prevent premature drainage.

Check the Contacts:

 Make it a habit to inspect the contact points on the collar. Over time, dirt or your pet’s fur can accumulate, affecting the connection between the collar and your pet’s skin. Clean the contacts gently using a soft, dry cloth.

Avoid Submerging:

Even if some invisible fence collars can handle water a bit, it’s better not to put them underwater or get them very wet. Wetness can harm them and make the battery stop it’s working.

Regular Testing:

Aside from the monthly testing routine, occasionally test the collar’s battery even if you do not notice any issues. This proactive approach can help catch transmitter problems early on.

Replace Seals and Gaskets:

 If your collar has seals or gaskets to protect the battery compartment, check them for wear and tear. Damaged seals can let moisture in, causing damage to the battery.

Limit Time on Pets:

When your dog wears the collar outside, take it off during indoor rest. This helps the battery last longer and relieves your pet’s discomfort.

Avoid Extreme Temperatures:

Exposing the collar to extreme heat or cold can impact the battery’s performance. If you live in an area with harsh weather conditions, consider using protective covers or sleeves.

Regular Inspections:

Beyond just the battery, periodically inspect the entire collar for signs of wear, cracks, or damage. Addressing these issues promptly can prevent more significant problems down the line.

Follow Manufacturer Recommendations:

Check the instructions from the maker of your invisible fence collar. Different collars might need special care. Use these tips often to keep your collar battery solid and reliable. This helps your dog get clear signals and corrections. Taking care of the battery keeps your dog happy and safe in your yard.

When to Replace the Invisible Fence Collar Battery
