When people hear "Energizer," they probably think of the Energizer Bunny... their famous pink bunny mascot that's "still going..." after all these years. However, Energizer hasn't stopped working on their battery technology. Their latest product is called the "Advanced Lithium" and is reported to last up to 20 hours longer in Rock Band wireless controllers than their previous best, Energizer Max. In addition, they are 33% lighter than ordinary alkaline batteries... something that might be appreciated near the end of an endless set list.
In addition to lasting longer while you shred, the Energizer Advanced Lithium batteries feature leak-resistant construction and a 10-year storage life, making them "instrumental" in the proper care and feeding of your guitar controllers.
So, if that's not enough to make this newsworthy, then I'll throw this in, as well: Right now, through June 1st, 2009, when you purchase specially marked packages of Energizer Advanced Lithium batteries, you can get a free Rock Band DLC song. Ah, now you're interested. Well, convince your parents or your spouse that it's time, now, to stock up on batteries for upcoming emergencies... and use the 10-year shelf life as a selling feature to make them Energizer Advanced Lithium batteries... then liberate their codes from the packaging to get the free Rock Band download of your choice. Sweet.
