Taken CR2 3v Lithium Battery Compatible with Range Finder,Alarm Sensor Devices,Thermostat Sensors,Instax Camera,Lighting Equipment【Non-Rechargeable 3V Batteries】 850mAh Low Self-Discharge Pack of 12

Bought these for the remote for the dog's electronic collar. I had been purchasing Duracell, but they didn't seem to last long. So a friend recommended I purchase a cheaper brand in bulk on Amazon. So, I bought these, and first of all the price was extremely reasonable and these last a heck of a lot longer than the Duracell batteries that I was using. I would definitely buy these again.

I would prefer to use rechargable batteries, but they often don't fit right and certainly don't have the same power density. These have been extremely reliable and work every time. Very happy with them.

These are a great value and better than I can find locally. The CR2 size batteries aren't a popular size so they are hard to find and often are priced high. I have a few flashlights and a garage door opener that use these. They came in a box which they will make them easy to store though it is not a see through box. I took a volt meter and tested each one and they are all very close to 3v.I can not state the longevity of these batteries at this time as they would not have time to run down yet. They have an great rating and the "copper top" brand name ones are much more expensive so these are a much better deal.

It was a great price and very fast shipping. Highly recommend. Will buy again. Thanks

These batteries are good - I tested all of them, whole box, and all have voltage in range of 3.33-3.35 volts, which means that manufacturing process is good, so capacity variation will also be low. Installed couple of them into remote camera triggers (that's what I use them for) - all work fine.

its exactly what i expected it to be

Our security system uses these. Excellent price.

I guess these are better than nothing. At least it's a very large pack of batteries. Unfortunately, when I installed one of these brand new batteries into my rangefinder, the battery meter only showed two out of three bars. It's hard to say if this is the fault of the rangefinder or the fault of the battery, but I would lean towards it being a problem with the batteries. My range finder is not a cheapie one, so I trust its gauge. I tried a second battery, since they come wrapped in pairs, but both of them reported the same level in the range finder. Purchase with caution.
