Same story as many others. Unfortunately I am on my 4th replacement pack of batteries in 2 years - and have dealt with a dead collar w/o batteries for a number of months just to save some money. I no longer believe the statement your company has made that nothing has changed. It is easy to see from the review history that 2-3 years ago the battery life OR the electronics did change since battery life wasn't always an issue. It is a shame, when the batteries are working the system is just fine. But the most frustrating part is getting surprised when my dog finds out the collar is not working before I do. I hope you are working on a solution to fix this issue soon.
We apologize for any issues you've had with low battery life, Mike! We certainly do not want you to have to worry about changing batteries more frequently than is necessary. Please keep in mind that if you are using this battery in collars for a containment system, average lifespan of each battery is around 1-3 months, depending on how often the collar is brought to the edge of the boundary and activated. We would be more than happy to assist you with any battery problems you experience and can be reached at the number 1-866-738-4379.
