Another crock of shit debunked - who said you can't recharge non-rechargable batteries? This guy says you can
You can fully recharge a depleted 9v alkaline battery at 63mA overnight without problems. You can fully recharge a depleted alkaline AA battery all day without problems. I recharged both types of batteries twice, and I would expect them to easily take many more charges.
What a complete waste. Batteries are some of the most nasty "industrial" waste we create these days, along with old computers and cell phones. Next time you buy a few AAs from Duracell, think of it like buying a disposable car: drive it for a day and leave it at the junkyard.
