Invisible Fence® Brand Computer Collar® are powered by a specially designed 3-Volt Lithium Power Cap® Battery that Invisible Fence Brand recommends replacing every 3 months to ensure continuous and trouble-free operation of your dog's Computer Collar
Smart Shopper Tip on Batteries:
- You can save over 20 percent when you purchase a 1 Year 3-Volt PowerCap Plan - OR - Replace your nylon collar and save more than 20 percent with our 3 Volt PowerCap Bundle Plan
- Both of these plans automatically send you a fresh battery every 3 months - just change the battery when the new one arrives and your dog will always be protected!
- AND there are no additional shipping and handling charges.
All batteries have a shelf life. We recommend never using a battery that is more than 1 year old...
