No guesswork

We lost the instruction manual so buying the replacement batteries from Petsafe was easier than trying to figure out where to find the correct batteries for this collar. Price was affordable also.

Already weak

When these extra batteries arrived with the PetSafe PawsAway, we replaced the original batteries immediately, as they arrived dead. The replacement batteries worked, slightly. What was supposed to provide a 12 ft. radius would only work within 1 ft. - and still not well! However, in true Chewy fashion, I was contacted as soon as my review for the PawsAway was seen and I was refunded the purchase price without question! Chewy gets 5 STARS++ for Customer Service!

Dies too quick

I use these batteries for my dogs bark collar. They work great for a couple weeks but then they die again. I wish we could order these in a bulk package. :(

Fantastic product

Works exactly as described. Took a few days for my Jack Russell to pick up the process, but now he rings the bell every time he needs to go out.

It seems to work if owner is consistent

This product is not difficult to use. Once you get the collar to fit right, it does work. However, you have to be consistent and make sure the antenna is aimed at the dog. The only small problem is making sure the item is on or off. I usually check it by shocking myself on the leg.
