How often should I change the Invisible Fence Power Cap batteries?

In order for your Invisible Fence® Brand system to work properly, the Power Cap® battery in the Computer Collar® should be changed regularly. Battery life can be drained by several factors, including low temperatures, the number of times a dog challenges the system, and the fit of the collar on the dog's neck. On average, your Power Cap should be changed every three months. You can sign up for a battery plan through your local Invisible Fence professional.
