Four Pack Dog Fence Batteries for Invisible Fence R21 or R51 Receiver Collars

Q: Is Invisible Fence's #3V PCP power cap the same power cap as these being sold?

No, these are an off-brand replacement. The design is different, resulting in inconsistent fit.

Q: Will these work on Microlite collars as well?

I don't know. I have the Invisible Fence brand fence and the collars have Invisible Fence on the receiver. The batteries work well with them but that's the only experience I have. Sorry.

Q: I have a perimeter technologies invisible fence r21 replacement collar - the battery in the picture looks different, will this battery work?

I have the Invisible Fence brand and these replacement batteries work great. These batteries are round and just pop in. I believe they will work just fine for you.

Q: What is the shelf life of these batteries?

I ordered one package of 4 in November 2021 and they lasted us until July 2022, we ordered the same product in July 2022 since they worked so well, but the most recent package the batteries are lasting about two weeks. We’ve already gone through 3 and our dog is running amuck in the neighborhood. I have a feeling we just got a bad lot. Will try one more time….
