Rayovac Batteries at Sam's Club
HD has Rayovacs on sale sometimes for a pretty good deal..AA and AAA. Found some at SAM's Club that say Rayovac Advanced with a 10yr shelf life. I know the current ones I bought at HD awhile back say good thru 2018 so these will last a bit longer..actually twice as long. $18 for 60pk of AA and $15 for 48pk of AAA. They are packed in 4pk resale packs in the package which makes it nice for throwing in your BOB or anywhere else without having to worry about loose batteries floating around. Just passing it on.
