  • OEM fitment, lasts like I.F batteries
Size: 1 Count (Pack of 4)
Super value for money. I was tired of the extortion prices charged by Invisible Fence. They work just as well as the I.F. batteries.

  • Don't always last as long as the originals
Size: 1 Count (Pack of 4)
Direct replacement and cheaper than the brand name. However they don't seem to last consistently like the name brand. If you are going to use them keep extras on hand. Some have lasted 3 months while others only lasted a few weeks

  • Meh
Size: 1 Count (Pack of 4)
So… you can get two of these for the price of one brand name one. I think it ends up being better to just get the official ones. The casing on these is cheap and I had a few just straight up fall out. They are the same size and shape as invisible fence brand but definitely cheaper. They work, mostly. Have had duds where the connection isnt made when installed. Half price of brand name but also half as good so… yeah ... show more

  • AVOID...Battery dead after 3hrs
Size: 1 Count (Pack of 4)
Update 11-05-22...so far just 1 bad battery, 2nd battery lasted 7wks, 3rd battery still going, and 4th battery just installed today. These arrived the day after purchase. Batteries do not have any type of date on them. We have 2 invisible fence brand collars and I installed 2 batteries and 1 was dead after 3 hours. So while the price may seem reasonable, it's a bad deal when they die before they should. I'll update on how quickly the other 3 die. Avoid buying these. ... show more
