Best AA's
"Very long-lasting AA batteries. Pricier than alkaline, but definitely worth it!!!"
Great Product.
"Great Product."
Great Resource
"I get all my batteries and flashlights from battery junction and have never been disappointed"
Best of the best
"These batteries are unreal. How much more power they have in them than an apple line battery I was shot when I put it on a battery tester and they tested not 1. 5, but 1. 9 to 2. 0 app to how much more power they've got in 'em and how much longer they will last than an alkaline battery. I am glad that I bought 36 of them and will probably buy more. They're worth having. They have a 25 year shelf life, which is unreal 8 times last 8 times longer than an Appalachian battery. I'm telling you what if you want to get an ultimate battery, this is it."
Best AA's ever
"I swear by these batteries when a disposable battery is a better choice than a rechargeable. Not often, but it happens. Super long shelf life, higher energy density, and no puking inside the devices they power. I'll never use alkaline batteries again."
