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)

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

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

Fast service. Had just what I needed. Thank you

Good replacement battery

These batteries work well on our collars lasting about 3 months at a time.

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.

Easy to install and a great value. You get 10 for the price of 1 at most places. Highly recommend!!

I have purchased these replacement batteries for years. They used to last 2 months each. However after this last purchase in January, I noticed they were not lasting as long. I took a new battery out of the package and tested it. I found it was only 5.4 volts not 6 as advertised. Don’t know if they were on the shelf for a very long time but I most likely will not be buying from this company again.
