This is a very well designed and much more cost effective way to keep your collar functioning properly. Don't believe the scare tactics "it will void your warranty". These batteries are not going to damage your collar. I have them in 2 collars and they work just fine. I spent HUNDREDS of dollars over 20+ years with the Invisible Fence system. For a long time there wasn't a good rechargeable battery available. Now Circuitcell has designed a battery that fulfills that need. There are other rechargeable batteries out there but they have design flaws. A big flaw is a battery that is not protected from complete discharge which ruins the battery and it wont recharge. These batteries are designed to prevent that from happening. I know this sounds like a sales pitch for the company but it is not. I'm just a dog owner living in upstate New York who is thrilled to be free from the battery plan. If you buy these batteries and charger you will be free too. It's really a no brainer. You wont regret this purchase, in fact you'll be smiling all the way to the bank."Invisible Fence pet containment systems require a new battery in the dog's collar every 3 months. Invisible Fence dealers sell battery packs for around $15. This expensive battery ...This clip demonstrates how to quickly and easily replace a battery in Invisible Fence® brand dog collars.

For replacement batteries, please visit "We have 4 dogs with 4 invisible fence collars. As you can imagine, we were looking for a less expensive option to ensure their collars worked and kept them in the yard. We were buying 4 batteries, every 3 months at a minimum of $10 a piece ($120 a year). We found these rechargeable ones and thought we would try them. We did have a small hiccup on one of the chargers but the company was very quick to offer a solution. They did not take long to charge (about 15 minutes) and have lasted over a month on this one charge. I'm sure this depends upon how much the warning beep or correction happens and our dogs tend to stay away from the boundary. Report said batteries should last about 5 yrs so we'll see as time goes on. So far we are EXTREMELY HAPPY with how they operate. They were simple to charge and install. Thank you for this economical and environmentally friendly option."I decided to write a review to let others know that these batteries are great. They have surpassed my expectations. The real bonus is how much these batteries save me money. They are long lasting and ensure my dogs are secure. I normally buy the larger packs and keep them handy for use later on in the months ahead. If you are looking for compatible collar batteries for your Invisible Fence compatible collar these are great.
