5.0 out of 5 stars
I put these in some outdoor temperature sensors and they worked reliably down to -35 degrees C. They were still working 1 year later but I replaced them anyway just to be sure that they would not stop in the middle of the winter.

Topic Title Summary Views
   I posted this on another packaging, but there seems to be a lack of understanding on battery life.The shelf life of this battery is rated at 10 years. The shelf life of a standard alkaline is rated at 5 years. So it's twice a long lived if you don't draw any current.The mah capacity of this device (at low current drain) is 750. For the alkaline, 600. So it lasts just a little longer in use.There are 2 types of smoke detectors. One is wired into the house, and only uses the battery for backup when the power is off. For this application, the lithium should last about twice as long. Well worth the trouble of getting out a ladder.The other kind of detector runs off of the battery. This is the detector you added to a room without doing any wiring. For this case, you might as well use a alkaline. It's going to last about the same.This is a great battery for backup applications. Especially where hard to get to. Don't confuse loaded and unloaded life.
