PetSafe Dog Collar Batteries (2 Pack) Dog Collar Battery Waterproof Lithium Metal Product, Rfa-67d-11

This is a repeat order for me! They work perfectly in the collar we have, and the batteries work every time, have never had an issue with them. They also last pretty long which we’re thankful for.

These batteries are the perfect size for our wireless pet safe fence. They are durable and easy to install into the collars. We have them on autoship, so we never run out. They function as they should and are lightweight.

Fair and good price for the batteries that fit in my petsafe wireless fender collar. It's easy to install into a collar if you have the right piece if not you could probably use a butter knife. Long life unless you have a raptor testing the fence like we do.

We have 2 Pugs, 6 & 2 years old, that get plenty of exercise chasing various vehicles and strolling passerbys on the road in our rural development. All within the confines of our hidden fence. When we purchased the 2 year olds receiver 20 months ago the collar and receiver were somwhat different from the original. The original receiver (Hidden Fence) has 2-CR2023 watch batteries that can be purchased any where. The new Pet Safe collar takes the RFA-67(modular) battery designed to be water proof. I encountered numerous problems with replacement batteries and always assumed the batteries received were dead or very near dead upon receipt. Purchases made from Amazon and various retailers, Home Depot, Lowes, Tractor Supply, and various hardware stores seemed to have the same problem. The low battery warning light would not clear or within short order reappear. This seems to be a common problem as witnessed in reviews from 3 to 1 Star reviews. I finally called Pet Safe customer service and received information I want to share since it's not covered in the manual.1) Remove old battery. 2) Press and hold the correction level setting button for 30 seconds. 3) Insert new battery, ensuring proper alignment and tightening. 4) Press the correction button again and the collar red light will blink the number of you corretion level setting. The low battery blinking red light will stop and your good to go. Amazon has the best price I've found for the RFA-67 batteries. We love our Pugs, Zeus and Apollo and trust their outdoor antics to Pet Safe.Thank you Crystal @ Pet Safe and Pet Safe, for enableing us to give our Pugs a full acre to frolic.

I am not completely pleased with the batteries for the wireless dog collar, being expensive and exclusive - only these batteries work with this particular unit's collar. Although they 'lock' onto the collar by a turn of the battery with a screwdriver or coin, sometimes the batteries will often come off the collar into the grass being black are not always easy to find again.So these batteries do work well if they are properly locked in the collar, do last a long time *if* the dog isn't testing the unit all the time in trying to escape, the collar gives off static charge to correct the dog, of course the battery loses power, but if it isn't being used except to beep occasionally as a warning that the dog is getting close to the boundary, they last about two months on my dog.However, these are the only possible batteries one can use in the collar. You cannot purchase them just anywhere, but only at certain pet stores or farm-supply stores or online sites and that is very inconvenient if you need a new battery quickly. They do cost a lot, although online I can now find them a little more cheaply even taking into account shipping vs the cost of the gas to drive out to the only store that carries them.They are expensive and that is why only 4 stars. You can conserve by removing the batteries when I take off my dogs collar at night and she is inside. When the batteries are in, the unit is in the ON mode and the they are constantly draining power just like a cell phone charger regardless of whether or not there is a shock, so I just remove them when not in use and the battery lasts a lot longer.I wish I could find another brand to try to make a comparison to see if others last longer, but this is the only one like it I've found.These batteries are as expected and even saves you a few dollars from the local hardware store that carries these. I wish the battery life was longer because I go through 10 or more a year. Good product and does as advertisedBought the batteries for my wireless pet containment system. These batteries fit the collar no problem and the shipment was very quick.

These batteries work well and last a while with our pet safe products. We have tried off brand replacement batteries and they just don't last or are completely dead right out of the package. This product is a highly recommended replacement.

So easy to replace, my 10 year old does it! Perfect fit for the color. Lasts about 6 weeks! Works great.

Good price for these batteries.
