There’s no question that batteries power our lives. Chances are, every room in your home is host to at least a handful of battery-operated devices. And chances are, you’ve probably needed batteries in a pinch — say, when the remote unexpectedly dies while you’re binge-watching your favorite show, or the dreaded “batteries not included” disclaimer went unnoticed in the fine print of a new purchase, causing a gifting disaster.

Maybe you’ve reached your arm into the abyss in between your couch cushions, hoping to make contact with a forgotten pair of AAs — or maybe you’ve rummaged through every catch-all drawer and box in your home, looking for spares. Personally, I’ve swapped the triple-A batteries in my bike lights and graphing calculator (nerd alert) back and forth more times than I can remember. I’ll sadly never see them simultaneously functional.

The next time you’re in dire need of batteries and can’t beeline to the store quickly enough, know exactly where to look right off the bat. Scroll down for our interactive battery locator, tailored to every room in your home. (Just remember to put them back after you’re done with ‘em.)
