PET Standard Replacement RFA-67 6V Lithium Batteries Compatible with PetSafe Battery-Operated Pet Products and Specific Dog Receiver Collars - RFA-67D-11 (Pack of 10)

These are easy to replace in my dog's perimeter collar. He wears two shockers to keep him from going walkabout at night. We live on a farm and can't fence him in completely and the wireless perimeter reminder (shock) system works well and he knows his limits. But sometimes he is willing to take a few seconds of zap to go on an adventure in the woods or in the neighboring subdivision. We replace these about once a month when the unit starts to blink red. They work well with an embedded 2032 coin sized battery inside (which is very hard to replace without wrecking the battery case), so we buy these to replace the batteries. They pop out with a half turn with a screwdriver and go back in the same way.

Worked as intended.

Fit collar worked well.

I have used these several times I the past and most of the batteries work great. However there are usually 1-2 per pack that will only last a couple of days before having to be replaced.

I had no issues with these batteries. I've been ordering/using these for about 4 years now and they work as intended.

I tried these cheaper batteries to replace in my dogs radio collar. My dog was on the porch when I put the collar on her and she jumped up and ran past her boundary. I took the collar off and I tried it holding it in my hand at dog level it did not work until I walked back to the house thru the boundary all the way to the house and it would not stop until I turned I pressed the button. It would quit for a few minutes and start back up. I turned off and unplugged the transmitter the collar still sending out tones. I then took the battery out. I missed the return window for batteries because I bought them to have on hand before I needed them. I can’t return and now have no battery for my dogs radio collar.

Seem to work great so far in my dogs petsafe collar!

Fast service. Had just what I needed. Thank you
