Energizer Ultimate Lithium Long Lasting Leakproof Disposable Batteries

These batteries are so much more powerful than your average AA batteries. I use these outdoors for my motion activated security lighting, and the LED's seem to shine brighter with these as opposed to standard AA batteries of ANY other brand. The motion detect on my lighting also seems more sensitive, even in very cold or severe weather. I highly recommend switching over to these for those things you rely on to work every time you turn them on.
