Fuck those guys. Seems like a load of shit. They are just standard alkaline batteries.
The skeptic in me doesn't necessarily disagree with you. But as I just don't prefer (what I consider to be) the inconvenience(s) of rechargeables, this seems like the least-worst alternative. Do what you will, makes no mind to me. Though maybe some others don't care for rechargeables, either. ..I'll still support any company that espouses recycling in their products and/or packaging.
Wikipedia's Life Of Rechargeable Batteries sums up some of the rechargeable issues pretty well.
Those in a constant state of worry might think about picking up a small, portable battery-tester. They're not expensive, some test a wide array of battery-types, and a number are small enough to fit on a keychain. For overall versatility, compact size, and low price-tag, I'd recommend this one. Radio Shack may have some to choose from, if you'd like to window-shop a little before committing to one.
