Growing up with the DieHard reputation in auto batteries, I figured these batteries might not catch the "bunny" but they could at least keep "step". I was wrong, "dead" wrong! The expiration date on the pack was one year later, but 2 out of 3 batteries were dead. Originally, I replaced the 4 batteries in my electronic deadbolt, causing me to think the deadbolt was broken. I had no other batteries to test it with. I decided to put them in my TV remote...nothing! Then I tried a couple of small LED flashlights...very dim, if anything. My Sears store is 12 miles away, so I chalked it up to experience. What's frustrating are the great reviews...somebody is getting packs with more good ones. For me, fool me once but not twice. Great price, poor quality...I'll stick with the "bunny"!
