The problems that we often face with our gadgets are that they do not last enough time. That is why Energizer has created the Ultimate Lithium battery. The big question is do they last longer then other batteries?  Do they live up to the expectations? During my testing I have found them to last around ten more times then other batteries.

These Energizer batteries are made out of lithium My testing involved a few different scenarios. This included testing it in devices such as my camera and computer mouse. Just by using it in flash light (which requires one AA battery) I found that these batteries lasted around seven hours and five minutes. Really impressed that it got this long straight usage scenario. In my computer mouse before I have had issue and have had to switch batteries way to often, this could usually be once or twice per week. When I installed the Ultimate Lithium Battery I have not had to switch batteries for two weeks. Overall, I would recommend these Energizer Ultimate Lithium AA batteries to anyone that has an electronic device. Even though the price is higher I would say that you get a bigger reward and return with these batteries then what you get with other batteries on the market.  You could say that in that short time you use fewer batteries which means that you end up spending the same money since you do not need to use that many batteries any more.

• Creates less waste
• Great for long-lasting photography sessions
