Unlike humans, who operate on a delicate balance of ginseng, vitamin D, and middle-school history textbooks, most important gadgets harness battery power. Take advantage of the universal life source with today’s Groupon: for $10, you get $25 worth of batteries and more from Interstate All Battery Center at its Santa Rosa location.

Interstate All Battery Center leads the charge in power outposts, providing reserve-power road-trippers with brand-new batteries for their trucks, cell phones, computers, and more. With a vast storehouse of products, Interstate carries batteries for nearly every brand of laptop and PC, as well as a plethora of automotive batteries to restore sedans, coupes, and station wagons after a long night of headlight staring contests. Household powerables are also available, including 24-packs of AAs ($12.99) for bulk buyers, a 9V alkaline battery ($3.49+) for metronomes possessed by surprisingly funky eighth notes, and one case of Lite Brite fuel, distilled from corn syrup and Olympic silver medals. Old used batteries find comfy retirement at Interstate’s recycling center, allowing their former owners and well-meaning grandchildren to rest easy.

Because of its dedicated and enthusiastic sales staff, Interstate recently sold more than 1.5 million batteries in a single month—a quarter of the number needed to power the massive Red Green–shaped night light meant to replace the sun upon its inevitable explosion. A visit to Interstate guarantees the perfect combination of lithium, alkaline, and words of electronic encouragement necessary to recharge gadgets in your home, office, garage, or secret underground tattoo parlor.
