They work, but they die very quickly.

Purchased the batteries on December 24. It is now January 18 and all the batteries are dead. I don’t know if I just got a bad batch or what the issue is but at this point I would not recommend these batteries. My dog was almost killed in the road due to dead batteries on 2 different occasions.

We have an invisible fence and these batteries are compatible with our dogs collars. I love that they are a fraction of the cost! Very dependable product. Quick to receive the item!

I was skeptical at first reading reviews for different replacements for my invisible fence collar. I read that some battery's would die after 10-15 days (90 days typical with brand name) and I can confidently say that these are just as good or better then the named brand ones. Def got 3 months out of one battery (5 pack). The brand name ones you get are a total rip off with their subscriptions. This 5 pack cost less then 1 battery of the brand name. Save yourself some money and get these. You won't regret it.

My dog is on invisible fencing and the batteries last long and fit well into the collar.

Two of the batteries had broken cases, one was still in the original packaging. They are not worth the money. Especially when we lose the chance to even use them in the collars.

Works with electric fence at much less of a cost. Will need to see how long the batteries last to make the real comparison. But until we know that great product.

One of the batteries arrived broken but it was still a good deal and works well in my dog’s electric fence collar. Will definitely reorder when I need more batteries !
