Energizer Ultimate Lithium AA Batteries (1 Pack), Double A Batteries

For those unfamiliar with battery chemistry here it is. Most alkaline batteries start out providing 1.5V of energy for a short while and then begin to drop down until they are so low on voltage they do not work. Lithium ultimates stay at a full 1.5V until completely dead. You get full use from new to dead. That is the advantage and why they are expensive.

I always knew that Energizer batterer's were around. I also knew they were Lithium batteries. I didn't really know what Lithium met when comparing them to alkaline batteries. Last Fall when I discovered battery operated outdoor Christmas lights, I did some research. I was amazed at what I found. Energizer Lithium batteries will last much longer than alkaline! They can last up to 8-10 times longer in high-drain situations (i.e. cold temperatures, high-tech devices like cameras or drones and have a 20-year shelf life) They come in all sizes AA, AAA, C, D and others. They are compatible with most of what you need around the house. They perform well and can be operated from a distance. They are available on Walmart for a very reasonable price.
