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)

Works well. Not as long lasting during friged weather. Durable.

I have used the OEM battery in the past and will usually get almost 4 months use with my dogs. These lasted about 2 months before I noticed the low battery light. Half the longevity, but 1/3 the price. Still within the description provided, so I consider this a good investment. Time will tell if the last batteries still hold up when used.

Not working this time - bought a second pack - still not working. Honestly, I consider it a great buy - because I truly think it is the collar or the system. Either way - as silly as it may sound - I consider it a WIN - WIN. If it is an issue on my end - thank God I found out. If it is a battery issue (which I highly doubt) I am sure the seller would work with me on a replacement or money back or worst case scenario - MY BEST friend is safe, happy and healthy. What more can I ask for? Simply a resolution to keep my baby safe. Buy them - they are a great product and the customer service has always been wonderful 👍

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.

Always pleased with the battery's they last in my dogs collars for about 2months great product

We’ve had our pet safe fence for several years now, same 2 dogs. Pet safe brand batteries last around 2-3 months for my most active fence tester and around 3-4 for the other that never gets close to the boundary.Some in this pack were ok and lasted around 2 months max but several had to be replaced within days of installation. One would think a battery should last more than a few days since the dogs are remaining in the fence.Thankfully my dogs are well trained and rarely exit the fence, even with dead batteries but ⛔️**** if you’re needing the batteries to actually work to keep Fido or Fifi from running away/safe, you should spend the extra money and get pet safe brand! ****⛔️I will be purchasing another pack because my dogs are well trained and won’t get lost. I’m also hoping perhaps I had a bad batch but others should know:—-I’m giving them one star DUE TO SAFETY REASONS. I hope this review saves someone’s floofer from running into the street thinking “I just changed the battery, they will be fine” again, if your dog depends on this for safety, do not buy this brand!—- There may be a quality control/function issues. Others have said they fall out.—-You won’t technically get the number of batteries you think you’re getting if some of them are doa or only last a couple days but the price alone is unbeatable. You can afford to have a few DOA at this price point (Unfortunately I didn’t write down how long each battery lasted compared to the pet safe brand but it was definitely shorter based on my order history alone)—-Unlike others that rated these low, mine stayed in, no issue with them falling out however dying within a couple days is worse in my opinion due to a false sense of security

These batteries are better than the knock offs!

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.
