I always used only PetSafe brand however in an attempt to save money I purchased a different generic brand... never again. Every single one of the others only lasted a week, therefore I went back to the PetSafe. I gave only 4 stars this time as one of the batteries only lasted a week... the only time this has happened to me with this brand. I will continue to purchase only this brand.
These batteries are complete garbage. When they fail after a couple of days and your dog wanders off you will regret ever thinking about saving some money. I thought it might have been a fluke so I tried another then another..... They are either bootlegs or expired and being sold as fresh. Buying batteries on Amazon is a mistake and it is a mistake I won't make again.
I’ve have been using theses batteries for several years and they are great. A lot cheaper to order through here than to buy them from a pet store or other commercial stores. Worth every penny and keeps my fur babies safe from harm.
