The only thing worse than realizing your remote control/razor/digital camera has killed it's batteries is peeking in the kitchen/utility closet/desk drawer and finding exactly one fewer battery than you need. No—scratch that—it's far worse to find all the batteries you need, but then to discover that they've run out of juice (Try sticking 'em in the fridge!). But what if you could make batteries last longer in standby devices like remote controls for just a wee bit longer...

This concept aims to nip the problem of early-de-charged batteries in the bud with an on/off switch.

The "switch" looks to us like a completely mechanical feature that hides the positive node into the body of the battery when switched "off," meaning that the remote control for the DVD player that might only get turned on once or twice a month doesn't suck any extra juice out of your batteries.
