nice buy

I use these batteries in a MS-5 dog collar for a smart dog door. I have never had the batteries die on me. But I change the battery out every 3 months. I need the collar to just work. I am happy with my purchase.

It seems to me these battery should last at least three months, but they only last two. I have two different dogs and every two months I have to change both batteries. However, for the price, the value is good. There is easy to install as the original manufacturer.

Price and quantity are reasonable.Would appreciate a shelf life date. I have 3 pets wearing sensor collars so high traffic in and out pet door. Quality could use improvement.

They work really good I have gotten about 3 months use from them. I am going to order my second round of batteries. I have 3 dogs so we go through them a bit faster than someone with one dog.

Complete two thumbs down. Every one of the 10 batteries were dead. Had to throw them all away.
