I've had an invisible fence for 20+ years. Multiple dogs. Multiple collars. One thing that remains, is the need to replace the batteries. The company tries to get you with battery plans. Maybe there is value there, but maybe not. I saw these non-OEM and had to try them.Pros:- two pack- they fit just as niceCons:- The top lip is slightly larger (as seen in photo)Product Aesthetics and Features:These look very similar in color, shape, and style. The wording on the top of the battery is slightly different from the OEM batteries. But the key is, do they work. I inserted them into one of my dogs collars, and the battery was recognized and blinked green as expected.Product Quality and Durability:I am unable to comment, with personal experience, on long term quality and durability.My initial views on product quality and durability considering the materials and construction are:I don't know if these last as long. Time will be needed to tell. The one draw back is that they did not feel as tightly locked in. Meaning it left me doubt if it was really secure or not.Using a scale of Poor, Average, and Excellent for product Quality and Durability.Personal Rating: averageProduct Value:This review is not explicitly about the cost, rather the personal value at this price point.At this time of this review this product was priced at $15.99Any time you can find a bargain on invisible fence batteries, I say got it.Using a scale of Poor (overpriced), Average (appropriately priced), Excellent (great value for price).Personal Rating: ExcellentProduce Origin:Made in ChinaPrimary reason for the star rating:The doubts about if they were locked in is the primary reason I went 4 instead of 5.Conclusion:Considering everything mentioned aboveWould I recommend this: Maybe (Yes if they prove reliable)Would I buy this again: Maybe (Yes if they prove reliable)Disclosure:This is my own personal Amazon Vine review. It is an honest and true account of my own views, opinions, reactions, expectations relating to this product. I did not purchase this product, however I was provided this product for the expressed purpose of providing a review.

Works with Invisible brand Invisible Fences collars without any problems. Slides in and locks in place wth ease and has been working steadily with no discomfort or disruptions that I can see. I love my fence, it has been incredibly helpful in keeping my dogs safe. But the brand batteries for the collars are very expensive if you buy direct from company. This is excellent replacement!

I recently replaced the batteries in my dog’s Invisible Fence collar with the Dog Collar Batteries and I’m thoroughly impressed. These high-capacity lithium batteries fit perfectly into the collar! These were super easy to install and were super easy. I’ve noticed the battery life lasts much longer than the previous ones I had, which is a huge plus!They’re also waterproof, so I don’t have to worry about them malfunctioning if my dog gets caught in the rain. The quality control and eco-friendly materials, and I love that they’re safe for my little puppers! Overall, these batteries are an excellent replacement—high-performance, long-lasting, and safe. These were the perfect fit super happy with the quality!

I have used an invisible fence to corral my dogs for many years. Replacing the batteriesis always a chore, as it is both expensive and often batteries die quickly.I was excited to test out these batteries as they are new on the market, and looked like a goodfit.They were easy to install -- and were a perfect match for my invisible fence system. I have usedthem now for some time, and the charge is holding in very cold weather (colder weather hastendency to be hard on batteries). I really like these as the cost and efficacy are both a good match.SummaryInstructions N/AFeatures Worked 5 out of 5 Batteries are holding a charge wellDurability N/A (they are protected within the collar case)Ease of use 5 out of 5 Easy to install and a perfect fitTotal 10 out of 10 (100%)

These dog collar batteries are a fantastic replacement option for anyone using R21, R22, R51, or Microlite receiver collars! The batteries fit securely into our invisible fence collars and are compatible. It’s clear that these were designed with precision and care and didn’t fall out, even during my dog’s most active moments. These batteries power the collar for extended periods, which means fewer replacements and more peace of mind. My dog’s collar has been functioning flawlessly, and I love that I don’t have to constantly worry about the battery running out power and my dogs possibly escaping from the yard. The waterproof design is a lifesaver. My dogs loves playing in the rain and splashing through puddles, and these batteries protect the collarfrom water damage effortlessly. The batteries are lightweight, mercury-free, cadmium-free, and environmentally friendly, which aligns with my values. Despite their eco-friendly design, they don’t compromise on performance—they offer a superior energy density for lasting power. Compared to other ordinary dog collar batteries, these stand out as both cost-effective and reliable. These batteries deliver consistent power, ensuring the invisible fence works as intended to keep my dogs safe. I highly recommend these replacement batteries for anyone looking for a dependable and high-quality solution for their Invisible Fence system.

We love our Invisible Fence, but we don't love the price of the OEM batteries. These batteries offer identical performance as the OEM version at half the price. I did have to give the tiny prongs a slight bend outward, but this isn't worth lowering my rating seeing as I've had to do this for other brands as well. Recommended!
