Need for wireless dog perimeter control,
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. Read more
