I have been using Tenergy Rechargeable AAA batteries exclusively, ever since I found them at Fry's Dallas location. I still have my Tenergy TN160 12 slot AA/AAA battery charger and I use it everyday! Tenergy Rechargeable AAA batteries have saved me about $1000 a year by recharging vs buying a 20 pack of conventional Alkaline batteries every week for $20.00 a pop! I'm service tech that works on commercial coffee equipment, combination fountain drink/ice maker equipment, etc., for a very large convenience store corporation. I don't use my flashlight occasionally, I actually carry two, with freshly charged Tenergy AAA batteries in both. Do the math! A 20 pack of Alkaline batteries is now over $22, so $22 x 52 weeks = $1144 a year, just for freakin' batteries so I can do my job! And on top of that, figure the carbon footprint for all of those batteries going into a landfill! Our beloved parents did not understand how they were polluting our land and water. All they cared about was making their fortune by stripping all the natural resources, then dumping all of their pollution back into the environment. They even said that the effects of pollution are nothing but lies, dreamed up liberal Left Wing radical hippies. It's all a lie they said! I dare them to say it now. Any way you look at it, rechargeable batteries by Tenergy outlast, out perform, are better for our environment and just make good sense for your wallet!
