So far, so good for this replacement battery! I have only had it a few weeks but it was easy to install and came up to full charge within 24 hours according to my Craftsman garage door opener lcd message screen. I did pull the plug on the opener, pressed the remote and the door went up and down fine (I only tried one complete cycle, which I thought reasonable) under battery power. Plugged the opener back in, saw the power restored, battery charging message scrolling on my message screen again and 24 hours all is quiet and normal again. For half the price of the brand name replacement I am pleased so far! Our original Die Hard battery that came with our opener only lasted 3 years by the way, so that will be my benchmark standard for this one. Update: July 10, 2107 Beeping from opener has returned and message on screen says to replace battery. We very rarely have power failures, and I have never had to run the opener with just battery power since my aforementioned original test when it first came up to charge. So, this battery lasted only about 2.5 years before failing. Is it worth it? It did last nearly as long as the original, and costs roughly half what that OEM battery would run….so I'd say begrudgingly I suppose. Why oh why can't these things last longer?!
