Questions & Answers

In what voltage range are you operating?

Those fit the Invisible Fence, but I don't remember how they looked. It is important to be wary of the buyer. What a waste of money! The odds of you buying a six pack and having four of them not work are not uncommon. The other two might also work, but only for a short period of time. This is what I have to say. I know because I experienced it. Alternatively, you can visit the Invisible Fence website and purchase them there. Even though they are more costly, they are worth it. You can read the reviews and they essentially say what I am

What is the battery life of these batteries?

Batteries like those in the Invisible Fence kept us going for as long as we needed. It would also be vital to consider when your dog is repeatedly getting too close to the "line" and setting off the collar by approaching it too closely.

Can you tell me if these are the same batteries as the invisible fence power cap?

Definitely, these batteries can be used to replace the Power Cap batteries in the Invisible Fence.

What collars are compatible with the R21 receiver for invisible fences?

these are the collars for the 700 Series R21 systems.

Selected User Reviews For Six Pack Dog Fence Batteries for Invisible Fence R21 or R51 Receiver Collars by Perimeter Technologies

I'm not quite sure that it is genuine
5/5

In all 3 collars I have for my dogs, I only use Perimeter batteries. My dogs never test their boundaries, so I have always been lucky, and I'm fortunate to have them last so long. These were different from the products I've received in the past, which came in sealed, hard bubble plastic with cardboard backing, as I imagined. This time around I received the sealed, hard bubble plastic with cardboard backing and loose battery in a ziplock bag. Basically, this gives me the impression that the battery could be of any brand and that Perimeter just put it in the bag with the perimeter logo. My guess is I will order from this vendor again, but not for as long as they last. My suspicion is that there's something fishy going on here.

This app is horrible and doesn't The order for 6 has been placed
3/5

I used them twice and they worked once and didn't work the other times. Also, I couldn't find a way to return them, so (around) $28 dollars were wasted. We wish there were some way to return them, but they can't be returned to us. This is even more frustrating for me since I have never had an issue with my batteries.

The importance of reliability cannot be stressed enough
5/5

This brand of batteries I haven't bought for over a year now, I've been using less expensive batteries instead. It was very disappointing to find that the other batteries didn't last as long and I had problems right from the start. It is not affordable for me to have my dog's collar fail, as my 120lb Great Pyrenees will simply keep running away. I'm back to these since they're reliable and so I should be able to trust them.

There is no reason to charge too much for Invisible Fence. You are much better off with this purchase. I received it fairly.

The five-week period did not last
3/5

believe the batch I received was bad. It took me almost 6 months to use the batteries that I bought from invisible fence when I had been told they would last only three It will take four months to complete. The batteries I bought weren't able to last five weeks after I tried them. They were so short lived that I cannot believe it. There must be a mistake in the first set, so I ordered a second set. It will be interesting to see what happens.

The strength is not enough
3/5

I can't find a model number on the Invisible Fence collar that I got for my dog. Since they are the same shape and size as our IF-100, we bought them There are a variety of batteries available. There was no tingle at all. I was able to carry the collar in my hand and carry the dog around the perimeter without it tingling. In the battery department, we stayed with the IF brand.

3/5

In terms of their arrival, I can say they arrived quickly, but I have not tried them yet. In order to avoid running out, I've ordered spares, and I'll be able to test them.
