About 15 billion batteries end up in landfills each year, creating not just trash but ultimately soil contamination and a laundry list of other environmental impacts. Consuming fewer batteries is ideal, and to that end, Silicon Valley-based Batteroo has released its eponymous battery life extender, a thin, simple ‘sleeve’ that slips over a battery and draws out its usable power to prolong its life.
Batteroo is a miniaturized voltage management and delivery
system. Stainless steel, less than .1 millimeter thick, these reusable
devices can significantly cut the number of batteries we buy, use, and
throw away (which makes the battery companies not too happy).
