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
Batteries work well and have a long life Read more
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. Read more
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 Read more
Great product at a great price Read more
We’ve had our pet safe fence for several years now, same 2 dogs. Pet safe brand batteries last around 2-3 months for my most active fence tester and around 3-4 for the other that never gets close to the boundary. Some in this pack were ok and lasted around 2 months max but several had to be replaced within days of installation. One would think a battery should last more than a few days since the dogs are remaining in the fence. Thankfully my dogs are well trained and rarely exit the fence, even with dead batteries but ⛔️**** if you’re needing the batteries to actually work to keep Fido or Fifi from running away/safe, you should spend the extra money and get pet safe brand! ****⛔️ I will be purchasing another pack because my dogs are well trained and won’t get lost. I’m also hoping perhaps I had a bad batch but others should know: —-I’m giving them one star DUE TO SAFETY REASONS. I hope this review saves someone’s floofer from running into the street thinking “I just changed the battery, they will be fine” again, if your dog depends on this for safety, do not buy this brand! —- There may be a quality control/function issues. Others have said they fall out. —-You won’t technically get the number of batteries you think you’re getting if some of them are doa or only last a couple days but the price alone is unbeatable. You can afford to have a few DOA at this price point (Unfortunately I didn’t write down how long each battery lasted compared to the pet safe brand but it was definitely shorter based on my order history alone) —-Unlike others that rated these low, mine stayed in, no issue with them falling out however dying within a couple days is worse in my opinion due to a false sense of security Read more
