PetSafe 3 Volt Replacement Battery - 2 Pack - Compatible 3V Products Such as Pawz Away Receiver Collar and Deluxe Anti-Bark Spray Collar – CR2 Lithium Metal Batteries

They work.

I purchased these with one of the pet sensors. It was a good thing too because the batteries in the actual collars for the cats were dead when they arrived. Glad I planned ahead.

These work in our electric fence collar and now that they’re on auto delivery every four months, I won’t realize the batteries are dead only when the dog escapes

This is the best price I've found to date, and the batteries were shipped promptly. I'll definitely order again.PetSafe Two 3-Volt Lithium BatteriesUpdate April 2010: I again ordered this product, and am still more than pleased with the prompt shipment, and great price!

They weren't the right ones for what I ordered them for, but I can use them for other things.

The negative review is on the listing as opposed to the product itself, which is tied to the wrong product.I am apparently not the first one to be fooled. You type RFA-67 and this is the third item that comes up. It is difficult to tell the difference in the picture of this Amazon listing. These are just basic off-the shelf button batteries (appear just like CR2032 which are generally $1 or less each), and are NOT compatible with RFA-67. I have asked Amazon to modify this listing so it does not mislead others.

great 👍

I was so excited I had found these batteries for my dog's shock collar for cheap! And then they arrived and they are NOT the same batteries as the ones in the picture. Don't make the mistake I did and trust the picture!
