FREE: 4 Brand New Sealed AAA Energizer "20 Year" Lithium Batteries

The listing, 4 Brand New Sealed AAA Energizer "20 Year" Lithium Batteries has ended.

* I just received these today from Amazon. It turns out, I don't need them.

* Believe it or not I think the date stamp is for December 2035! The package advertises that they hold a charge for 20 years. This may not be out of the ordinary for lithium batteries of this type, I don't know.

* Lithium batteries are useful for things like:

+ Outdoor thermometer gauges (the ones that actually sit outside), because they have a wider temperature operating profile than alkaline batteries.

+ They also work better (last much longer) in digital cameras and other similar digital electronics because of higher capacity and lower internal resistance allows moderate to heavy loads.

+ They offer superior leak resistance.

+ They are much lighter than alkaline batteries.
