RFA-67 RFA-67D-11 6V Replacement Battery Long-Lasting & High Capacity Compatible with Pet Safe Electronic Collars Pack of 10

So far so good. Just put the battery in today 9/9/25. Her battery had died and she was going outside her boundaries and today she found out she no longer is able to go outside her boundaries. The battery was easy to replace. No issues. I'll update my review in about a month or so to say how long it lasted.

I was hesitant to try a non-name-brand battery for my PetSafe collars, but these completely won me over. The price is unbeatable for a 10-pack, and the quality is every bit as good as the originals—if not better. They fit perfectly, last just as long, and I’ve had zero issues with performance. With how often these collars go through batteries, this bulk pack is a real money-saver without sacrificing reliability. I’ll definitely be sticking with these from now on.

Works like a battery should!

Sadly, these don't work. We have a Pet Safe brand collar and these are the right battery but cheaply made and while they sometimes randomly make contact and work, most of the time they don't. Obviously I don't trust the safety of our pet using this battery in his collar so they were money wasted for us.

While these don't last quite as long, as the Petsafe brand, the cost more than makes up, for it.

Worked well in my dog’s collars. I don’t know how long they will last.

Item just as described

Last a good, long time. Fit like a glove in the pet safe collar.

Only got 4 batteries
