Nice having the batteries need for a wireless cat fence and a multi pack at a good value. Shipping is always great and fast.

4 out of 5 DIDN'T WORK

These are not the same as the Petsafe batteries that we know. Waste of money.

I was hoping These were the proper batteries for my R12 Fidos Fence wireless collar. These batteries are impossible to find outside Fido's Fence where two batteries cost $50, a rediculace amount to pay for two disposable batteries.

These are not Petsafe batteries. They will work for a while but within a month they will fail, not because the battery itself goes dead but because the battery housing is weak an will break. Go with the PetSafe brand. It will cost a bit more but they last a long time

Do not buy these, they fall apart and difficult to turn on and off

After one month of using one of these batteries to replace the battery in our PetSafe collar for our inground fence, the plastic fell apart and popped out of the collar. The plastic actually disintegrated. Also, these are much harder to turn on and off than the original batteries. This means, that you have to be delicate with a coin or you will strip it out. We have 3 chihuahuas who are not hard on these collars - in fact, the first one fell out of the smallest (under 5lbs) one's collar. We do not leave the collars on the dogs while they are in the house and have resorted to leaving them off of the dogs but turned on while they are off so that they do not fall apart as quickly. I would rather the battery run down quicker than not being able to use the item at all. This is a huge failure for a product that requires a battery replacement that is more than the battery itself as something normally would call for. These enclosures are proprietary to PetSafe collars which significantly limits the ability to easily maintain and replace batteries. I would not recommend these batteries at all.

They work so far

First time to order these batteries, usually order the Petsafe. Hoping they will do as good as the top brand.

Broke first day

These non brand name battery's breaks off and are hard to turn. The plastic shears off and we had to dig the battery and plastic around it out of the collar.

These non brand name battery's breaks off and are hard to turn. The plastic shears off and we had to dig the battery and plastic around it out of the collar. I was afraid the collar would be ruined. I don't know if I can return them or not.
