BlueDot TradingSingle Pack 2CR1/3N Lithium Cell Battery 3V for Dog Collar, Cameras, Flash Equipment, Calculators, Game Controllers, and More, 10 Packs

I bought these for my dog's Invisible Fence collar. They are the right number and spec., but they are just about 1/16" longer than the original battery and won't fit in the collar. Too cheap to return. I just threw them out.

This is not a 2CR1/3N It is smaller than the real deal

Got these to replace the battery on my dogs shock collar. They work perfectly and cost a fraction of the price. If you're going to use these for the same purpose make sure you remove the plastic sleeve around the battery before installing.

The part number was right, however, when I received the battery it was not what I needed. The battery was too small to fit into my Canon AE-1 camera. Thank goodness I only wasted $6.00 on this item. I will not buy things sight unseen again.

Very good price

These were exactly what I needed for the appliance I have.

Great product so far

Good
