I have a 7 year warranty on these batteries how do I get more? it’s been a whole year and some now?

My understanding is that you have to contact their customer service department. However, there may be a catch, in that you would have had to given them a positive review within their allotted time frame so as to be registered with them. They only give you a week to review the product.

Interested in buying for dog fence collar. How long do these typically last in your dog collar? Would you buy the batteries again?

I use these batteries for my 3 Boston Terrier's dog collars. If I buy batteries from the collar manufacturer they are $20.00 for one. Amazon price is $13.95 for ONE. They are shrink-wrapped and when cut apart they are 2 CR1/3N 3V-B6 Lithium batteries. A six-pack of the CELLEWELL CR1/3N 3V-B6 Lithium batteries about $2.50 for each battery! And they are the longest-lived dog collar battery I've used.
