We buy these for dogs electric collar every six months. They work as well as the expensive ones we’ve purchased from other vendors.

These are bad batteries. Both of these died within 3 weeks. I’ve ordered before directly from Perimeter Technologies and never had this problem. Save your money and order elsewhere.

The battery life on these is definitely not as good as the name brand but the price is right, I have used them for the past few years and I know what to expect. However, with that being said I have rec'd some that were dead almost immediately. So it might be a crap shoot but I'll keep using them as the original are very, very. pricy.
