Energizer Energizer AA Lithium Batteries, Double A Battery Ultimate Lithium (4 Count)

These AA lithium batteries have a shelf-life in the package of 25 years! The life of these AA lithium batteries makes them useful for battery back-up in smoke detectors that are hard-wired into the AC electrical system. The lifetime of these batteries as back-up batteries should be as long as ten years. The initial power is excellent, and the lasting power is the best. The cost at Amazon.com is quite competitive.

If you have an outdoor weather station or sensor like many smart hone devices do now a days you need to use lithium batteries in it because they’re good down to -20°C. It would be great if they were rechargeable but they do last quite awhile so I’ll give them a pass on that.

Always use these in blink cameras and door bell. Last about a year in camera and about 6 months in door bell. Door bell is 90% of the time set to active, ie alert if someone comes into frame so say thats why we only get 6 months use. Warns you roughly about 5 days before they die that batteries are low.
