You can’t think how much these very long. Recent best cr2 battery in the web market and it uses a lot and so far. It is so good and still going strong. There are no signs of fading. The extra little keychain light was also extremely bright (you didn’t expect much from that), very nice. I think you love the flashlight they gave you. You put it in your purse or pocket. It lights the whole thing up.
Use the batteries for the viewfinder. If you use the first time, I am sure after the end you order several times. This time we offer a flashlight with a holder. It’s small just right for a man’s pocket. The batteries last a long time — the best price for the batteries.

I bought these batteries for my husband. He needed them for some hunting equipment. They work fine so far, and we had them for very long. So I can’t speak about how long they will last. The little lighted keychain is pretty bright too — a good deal for three batteries.
