Energizer Ultimate Lithium AAA Batteries (4 Pack), Triple A Batteries

[This review was collected as part of a promotion.] In general energizer batteries are known for their longevity and effectiveness. 20 years shelf life is awesome for any battery. It's 100 percent leak proof which gives it a high safety rating and it works in extreme temperatures.

I use these in any electronic device requiring aaa batteries. They outlast ALKALINE batteries 3 times over in all of my devices. In electric toothbrushes they are superb making the toothbrush run faster and longer.

Don't settle for less than the best!

Certainly, these are expensive. And for some apps (like my electronic lock) it is worth not messing with on a regular basis.... For the critical issue, get these.

Typically cost a little more than brand name alkaline.. but tend to last longer, have a much longer shelf life, and will never leak any damaging corrosive chemicals or acids!
