Bob Roohparvar tells a killer story of industrial espionage. He says the robbery occurred last October at his Batteroo office space in a sprawling Silicon Valley office park. The target was intellectual property surrounding Batteriser, a simple metal sleeve that promises to give consumers up to eight times more life from their disposable batteries, AAA through D.

The crooks clearly knew the building layout, and exactly what they were looking for—namely, a breakthrough technology that, if legit, could blow the lid off an alkaline battery industry that's worth $3.4 billion annually in the US alone.

"It was a very, very professional job," says Roohparvar. "They passed by all the offices with open doors, and then banged the hell out of my door, breaking it in. The doorknob was slammed so hard into the wall, it got stuck in the plaster. They took my hard disk and a bunch of USB drives. They took our Batteriser samples. They knew exactly how much time they had before the police would respond."

Roohparvar, who has a Ph.D. in electrical engineering and a long career in power management including a VP stint at Broadcom and a CEO stint at FlexPower, says he's not worried about the theft, because Batteriser has full patent protection. But once the battery manufacturers grasp what Batteriser can do—assuming it works as advertised—they might be worried by this simple gadget, which will cost just $10 for a pack of four when it goes on sale in September.

How Batteriser gives your batteries 8 new lives

A completely new alkaline battery is rated to generate 1.5 volts, but once its output drops below 1.35 or even 1.4 volts, it effectively becomes useless to many devices. The battery's chemical cocktail is still loaded with juice, but the circuitry in many gadgets (especially more sophisticated ones, like Bluetooth keyboards and bathroom scales) considers the battery dead.

This is where Batteriser comes in. It's essentially a voltage booster that sucks every last drop of useable energy from ostensibly spent batteries. So, instead of using just 20 percent of all the power hidden inside of your Duracells and Energizers, Batteriser makes effective use of the remaining 80 percent.
