Card-carrying members of the Radio Shack Battery of the Month Club, get ready to salivate: The Eco USBcell is the most exciting development we’ve seen in rechargeable batteries in a long time.</p><p>
Unlike most rechargeable AA and AAA cells that use nickel metal hydride chemistry, the USBcell’s are based on the same advanced lithium polymer technology that’s used in many smartphones.</p><p>
That may not sound like a big deal, but one limiting factor in using LiPo in a AA or AAA battery is voltage. LiPo and Lithium Ion’s typical minimum voltage is 3.7 volts and would fry a standard device looking for 1.5 volts.</p><p>
The Eco USBcell features a power control chip to match the voltage to the standard disposable alkalines we’re used to. Lithium batteries beat nickel metal batteries in recharge time and the number of times they can be recharged. And when compared to disposable alkaline batteries they have an even bigger advantage.</p><p class="jumpTag"><a href="/article/3020072/hardware/the-eco-usbcell-is-the-slickest-rechargeable-aa-battery-youve-ever-seen.html#jump">To read this article in full or to leave a comment, please click here[/url]</p></section></article>
