B3V 1A Replacement Battery High Capacity Compatible with High Tech Electronic Collars of MS-4 and MS-5 Pack of 6

These batteries work great. Long lasting. Best value for money.

We buy these for out dogs collar to get in an out of the automatic door. They last well over a month or more. She is a little dachshund and loves to go outside to sun herself so she is in and out a lot. When the automatic door is slow to open we change out her collar battery for a new one because we don't want her to get stuck outside. So there is probably some life left in the battery which gets thrown away, but we love our dog like family and don't want any harm coming to her out here in the country where coyotes roam.

Great price, works in my dog collar. Thanks!

Reliable, long battery life and water resistant. Great value for the money.

Works excellent in our dogs collar for the auto door!Original battery lasted about 4 months and we had a month of single digit weather.Will see how long this lasts.

We use these batteries for the High Tech Pet Automatic pet door collars. We have 6 dogs that use them. These are much cheaper than the name brand and the quality is the same. Each battery lasts approximately 3 months. We have purchased these same batteries several times already and our experience has always been the same. Save yourself some money and buy these instead of the expensive ones.

We use this battery in our cat's collar - to keep her away from an area where she's not allowed.The cell is a generic Cr2032 that can be bought cheaper elsewhere, but I don't have the time nor patience to solder the special contacts on to it.We've replaced it several time - a cell lasts approximately 4 months in our environment, well worth it.

yep, worked
