"Very long-lasting AA batteries. Pricier than alkaline, but definitely worth it!!!"
"Great Product."
"I get all my batteries and flashlights from battery junction and have never been disappointed"
"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."
"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."
"This is a great value from a reputable company. Great prices always from Battery Junction and free shipping for $50 or more purchase."
"Battery arrived well-packaged in perfect condition."
"Best hi drain battery on the market."
"These batteries last for a LONG time compared to normal alkaline. 2-3+ years with some power still left when used in my security cameras. They won't leak if installed in a device for a while without any use. I will only use these in expensive devices where I can't use a rechargeable."
"Vastly superior to alkaline cells, these last longer, don't leak, and have better cold weather performance."
