UPDATE: This is a total hoax. Inside a 6 volt battery is 4 D batteries. So it seems you can open a 6 volt battery and find 32 AA batteries inside. Consider that a 4 pack of AAs costs around $5, and you can get a lantern battery for about $5, and that’s some powerful savings. [Lifehacker]

    The blister pack batteries were alkalines.

    Notice the outside of the lantern battery said “heavy duty”? That means it is not alkaline. If you want crummy, cheap, short shelf life, don’t run very long AA batteries, just buy them.
    Go compare the cost of 32 of the so called “heavy-duty” batteries in a blister pack against the cost of this lantern battery.

    I had a professor who said they forgot the word “not” in front of the “heavy-duty”.

    Cross posted onto Lifehacker because this is such a bad idea.

    Copying my post from Lifehacker:
    This is a waste of time & money.

    If you really want to save money, go rechargable. Having rechargable batteries is one thing, having a good charger is equally important. Many(most?) of the chargers you’ll find in the big box stores are great at cooking your batteries and killing their lifespan. Maha makes some very nice chargers [www.mahaenergy.com]
    As far as rechargable batteries go, the Sanyo Eneloop batteries [www.eneloopusa.com] finally make rechargables useful because they come pre-charged and don’t self-discharge anywhere near as rapidly as the traditional NiCd/NiMH batteries. This means they’ll work quite well in TV remotes, clocks, and anywhere else that you wouldn’t traditionally use a rechargable.
    The Eneloop batteries are “only” rated for 2100mAh, but you’ll actually get more performance out of them than other rechargable batteries with higher ratings. Most NiCd/NiMH batteries lose 10% (NiCd) to 15% (NiMH) of their charge within the FIRST 24 hrs of being removed from the charger, then another 10% per month after that. In contrast, the Sanyo Eneloop batteries only lose 10% after six months, and only a total of 15% after 12 months away from the charger. They’re claiming the Eneloops will last up to 1,000 charge cycles if taken care of properly. In a TV remote or wall-clock, there’s a chance these batteries might last longer than you do. At this point, there’s no longer a need for alkaline batteries. The better chargers are quite energy efficient (I’ve used less than $0.02 to fully charge 24 AA batteries), so even the arguements against the electricity used no longer are valid.
    Ironically, Wal-Mart & Fry’s both carry Sanyo Eneloop batteries with matching chargers, and the Sanyo chargers are quite good. Sure, the Sanyo chargers aren’t as fast, but fast charging severely reduces the lifespan of batteries.
    Personally, I normally buy my batteries & chargers from Thomas Distributing [www.thomas-distributing.com] and have Maha 401, Maha 800s, and Maha C9000 chargers. The “recondition” feature of these chargers has revived many “dead” rechargables which wouldn’t hold a charge.
    Also, beware of cheap mass-market rechargables. I have a pile of nearly useless rechargable Energizer 2500 mAh AA batteries here. All of them are less than a year old, all of them won’t hold more than about half their charge (~1200-1500mAh, measured) and some of these batteries are just 6 months old! In the meantime, I have a few Energizer 2050 mAh rechargables that are about 2 years old and still have 87% of their capacity left. Maha’s PowerEx batteries also hold up very favorably as well

    Assuming this is actually true, you can buy generic, non-alkaline AAs for around $0.13 apiece online. That gives you around 40 AAs for $5.

    Or you can just get some rechargeables, help the environment, and pay the equivalent of around $3 for 500 batteries.

    @cpatch: No one ever said college students were actually smart. Proof that they’re in college (instead of owning their own businesses at that age) is further proof.

    ack. accidentally hit the mouse. Proof that they’re still in college (instead of owning their own businesses at that age) is that they have way too much free time to come up with crap like this.

    ack, bumped the trackball before I was done typing.

    meant to say:
    No one ever said college students were actually smart. Proof that they’re in college (instead of owning their own businesses at that age) are stories like this where they have more time than brains and no street smarts to figure out that this is a total waste of time & money.
