PET STANDARD RFA-67 Replacement Batteries Compatible with PetSafe Dog Collars (Pack of 10)

Llegaron antes del tiempo señalado. Funcionan correctamente con el collar. Y duran lo mismo!

These are easy to replace in my dog's perimeter collar. He wears two shockers to keep him from going walkabout at night. We live on a farm and can't fence him in completely and the wireless perimeter reminder (shock) system works well and he knows his limits. But sometimes he is willing to take a few seconds of zap to go on an adventure in the woods or in the neighboring subdivision. We replace these about once a month when the unit starts to blink red. They work well with an embedded 2032 coin sized battery inside (which is very hard to replace without wrecking the battery case), so we buy these to replace the batteries. They pop out with a half turn with a screwdriver and go back in the same way.

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.

They were great and fit the collar without falling out!

Good thing it is a 10 pack. They have lasted about 48 hours each. So this is a 20 day supply. I suppose it is possible my collar is bad, but I will try the name brand batteries next. Edit: The batteries now seem to be lasting several weeks. I am satisfied
