    Energizer broke fresh ground when it made the first disposable batteries from recycled cells, but that immediately raised a question: where are the rechargeable versions? As of today, they're here. The company has introduced new Recharge AA and AAA cells that are the first to be made using old batteries. About 4 percent of their material comes from used power packs, including those from hybrid cars -- yes, the leftovers from your Prius could one day power a kid's toy.

    In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. If you're a geeky pack rat who likes to travel with a mini Radio Shack store in your bag a la Steve Wozniak, then you're likely always looking for ways to keep your precious devices powered up. One option that may be worth a peek is the POP rechargeable battery -- a portable power pack that eschews the brick-like design of many of its brethren and comes with 25,000 mAh worth of juice to help bring your gadgets back to life. According to POP creator and Edison Jr. co-founder James Siminoff, the portable battery has enough capacity to charge either 10 standard smartphones or 1 1/2 third-generation iPad tablets.

    We're here at CES Unveiled and just got our hands on Goal Zero's new version of its Sherpa 50 personal power pack. Like its predecessor, it's a 50 watt lithium ion power pack meant to give you an extra few hours of juice for your portable devices wherever you go. However, this new version is about half the size of its elder -- not much bigger than three or four CDs stacked together -- and has a removable inverter to slim it down even more. That inverter lets you use a standard electrical plug to re-power your gadgets, but the new Sherpa 50 also has ports built in to allow you to plug in your lap. Available this June, it'll cost $250 as a standalone product and $400 if you want one of Goal Zero's solar panels thrown in for true go-anywhere (as long as it's sunny) computing.

    Panasonic's little battery-powered bot that could, the Evolta, has garnered our attention several times over the years. It's already climbed out of the Grand Canyon and walked 500km from Tokyo to Kyoto, but apparently neither was enough to prove it and its namesake batteries' true mettle. This time, Panasonic's putting three of the robots through the Ironman Triathlon in Hawaii, and they've got a week to swim 2.4 miles, bike 112, and run a 26.2 mile marathon. Unlike the meatbags running the race who have a day to finish, the robots get a week -- though they'll be doing their thing 24 hours a day while only taking breaks to recharge their three AA batteries. Intrigued? The race starts on October 23rd, so there's plenty of time to watch the appropriately dramatic video explaining the challenge facing the triumvirate of tiny triathletes after the break.

  • Researchers use graphene and tin sandwich to make better battery electrodes

    Graphene, that microscopic chicken wire made of carbon atoms, has a great many theoretical uses. Among these is to improve Lithium-ion battery technologies, and the big brains at the Lawrence Berkeley National Laboratory have created a graphene and tin composite material for use in battery electrodes. When it's baked at 572 degrees Fahrenheit (300 degrees Celsius) the tin turns into nanopillars that widen the gap between the graphene layers. The greater volume of tin provided by these tiny towers improves electrode performance (read: faster charging), and the flexibility of the graphene prevents electrode degradation. Naturally, current prototypes can only maintain capacity over 30 charge cycles -- as opposed to the hundreds required for commercial applications -- so some serious improvement has to happen before we see it strut its stuff in any phones or EVs. This leaves us, once again, extolling the virtues of graphene, but lamenting its exclusively academic application.

    Soundfreaq made quite the first impression last year with its Sound Platform SFQ-01 audio system, which is why our ears perked up when we heard about the company's newest creations -- the Sound Step and Sound Step Recharge compact wireless speakers. Compatible with all iOS, Android and BlackBerry devices, these Bluetooth-enabled docks allow users to remotely stream audio directly to their speakers, which feature a set of 2.75-inch, Kevlar-reinforced balanced drivers, a dedicated sub-woofer and a UQ3 spatial enhancement processor. There's also a 3.5 millimeter line-in jack and a USB charging port, meaning you'll be able to juice up multiple gadgets as you kick out multiple jams. And, since these guys are just 3.6-inches tall, you probably won't have to freaq out about making space for them, either. If your appetite's already whetted, you can grab the Sound Step for $139, or opt for the Recharge (with its six hours of rechargeable battery life) for $159. Otherwise, you can find more details in the full PR, after the break. Update: We've just received a bit of clarification from the company here. A "grey" colored model actually won't be on the docket, and as for the speakers, there's a pair of 2-inch drivers + a single 3-incher.

  • Department of Justice probe eyes Sony's rechargeable battery business

    After the headache-inducing bout of hacking woes that beset the corporation in recent weeks, a new Department of Justice-led investigation into Sony's US electronics division may have the company emptying that aspirin bottle. Details of the inquiry are scarce at the moment, but with the company's cooperation confirmed, all signs lead to an alleged price fixing of its rechargeable battery business. Citing data from a Tokyo-based research firm, a Bloomberg report indicates that a 2010 market surplus had Sony Electronics (amongst others) lowering battery prices at the expense of less financially-cushioned players. The notorious sector of the multinational's operations has been in the hot seat before -- namely, for actual laptop explosions -- but this time 'round the judicial maypole, it seems the Japanese giant may have been partaking in some anti-competitive shenanigans. If the DoJ hammer does happen to fall on Sony's already bowed head, the company could be facing a very expensive slap on the wrist and a fundamental change to its business practices. Luckily for Sony, we happen to believe in a little something called "innocent until proven guilty."

    Quick: What costs hundreds of dollars and dies after four hours? If your answer included anything portable and tech-based -- you guessed right. In fact, most of our magical and exciting gadgetry has less-than-stellar means of holding a charge, but a recent breakthrough by Sumitomo Electric Industries could change all that. Employing the same process used to create Celmet (a NiMH component), researchers at the R&D company managed to coax aluminum into being a bit more receptive. The resulting Aluminum-Celmet has a whopping 98 percent porosity rate, leaving the Li-ion gate wide-open for a flood of electrical juice. And unlike its nickel-based brother, this piece de porous non-resistance has a steep corrosive threshold that could soon help power a line of high-capacity, small form rechargeable batteries. Production is already underway at Osaka Works, with SEI hoping to speed adoption of these franken-batts into our mass consuming mitts. Technical-jargony PR release after the break.

    Turtle Beach impressed the pants off of us last month with its Ear Force PX5 headset, which is why our mouths began watering when we found out that the company has two new gaming products on the way -- the Ear Force PX3 and Z6A. Much like the PX5, the wireless PX3 (pictured above) boasts 18 interchangeable audio settings and supports additional presets that users can download directly from Turtle Beach. Though it was designed with PS3 users in mind, the PX3 can also run on an Xbox 360 and is the first Turtle Beach headset to feature a rechargeable, ten-hour battery. The PC and Xbox-friendly, surround sound Z6A, meanwhile, rocks eight amplified speakers (including two subwoofers) and is juiced by a 5.1 channel amp that promises to bathe your head with booming bass. The USB-powered device may leave you tethered to your console, but at least it will house your ears in an oversized mesh cushion, which may make those late-night gaming marathons a little more bearable. The PX3 will retail for about $150, with the Z6A set at around $100, and both headsets will be on display at E3 next week in Los Angeles, so we'll be sure to give you our feedback once we get our paws on them. For now, you can sate your appetite with the full PR and an image of the Z6A -- both of which are waiting for you after the break. Updated: The Z6A is designed for both PC and Xbox platforms.

    Austin Whitney hasn't been able to walk since a 2007 car crash left him paralyzed, but on Saturday the 22-year-old triumphantly strode across the stage to accept his degree from UC Berkeley. He had a little help, in the form of a specially crafted robotic exoskeleton developed by Berkeley engineering professor Homayoon Kazerooni. Kazerooni and his team designed the exoskeleton with lightness and affordability in mind, resisting the urge to load it up with expensive hardware and tethering the mechanized walker to a backpack that houses a computer and a rechargeable, eight-hour battery. As a result, the Austin walker won't enable the kind of acrobatic leaps that would make Lt. Rasczak proud, but its reduced mobility comes at a reduced cost of just $15,000. That's certainly not an impulse buy, though it's a welcomed alternative to other exoskeletons that retail for $100,000 or more. Walk past the break for a video of Whitney's momentous steps, along with a clip of Kazerooni describing his creation.

    For humans, coming into contact with the third rail will likely void your personal lifetime warranty, but one accessory manufacturer hopes to apply a similar concept to your iPhone -- in much smaller doses, of course. For $90, the Third Rail System includes an iPhone 4 Slim Case, which always surrounds your device, and a 1250 mAh Smart Battery that you can slide into place whenever you need a boost. The removable batteries can charge other devices over micro USB, and can be stacked up to four deep for charging multiple gadgets at once (at $60 a pop). It's also designed to be compatible with future cases, negating the need to purchase another complete solution each time you upgrade your phone. We'd love to see a similar device that includes inductive charging as well, but for now, this is one of the most intuitive external battery solutions we've seen.

    We've seen plenty of portable solar chargers in our time, but few have looked quite as versatile as B-Squares -- a new collection of 3D modular energy storage devices that can be arranged in various configurations, according to the kind of gadget you're looking to juice. Developed by MIT grads Jordan McRae and Shawn Frayne, each solar-powered B-Square features a sticky microsuction surface, along with magnetic and electric contacts at each corner, making it easy to connect and arrange them in different formations. Rotating a single square will change its electrical circuit, depending on its adjacent connection. Some B-Squares, for example, feature LED surfaces, allowing you to create solar-powered lanterns, while others have solar panels, or simply serve as rechargeable battery sources. There's even a square devoted to Arduino boards, along with another surface designed to dock and charge iPhones. McRae and Frayne have already put together a full "recipe book" of different configurations, though the DIY route seems a lot more enticing to us. Their B-Squares are set to leave the prototype phase on May 1st, at an as yet unspecified price. Check them out in video action after the break. [Thanks, Ryan]

  • Flexible batteries get the graphene treatment, could be cheaper than other bendy batts

    We've been talking about flexible batteries for years now, but a team of Korean researchers have presented a new solution to bendable energy sources that is not only more powerful than standard lithium-ion batteries, but also potentially cheaper to produce than its malleable predecessors -- and unsurprisingly, everyone's favorite wonder material, graphene, is at the heart of the innovation. The rechargeable battery contains a vanadium-oxide cathode, grown on a sheet of graphene paper, an unidentified separator, and an anode made of lithium-coated graphene. According to the folks behind the new power source, it sports higher energy and power density, as well as a better cycle life than the literally stiff competition. Similar advances have also out-performed rigid lithium-ion batteries, but have enlisted carbon nanotubes, a material more expensive to produce than graphene. Of course, like all technological advances, we won't be seeing these things for years, if not decades, so you might as well get used to ye olde standard bearer.

    It's Christmas Day, which probably means that at least one toy that you received (or gave) won't be fully functional until Monday. Why? Batteries. It's an age-old problem, that "batteries not included" thing, and it's one of the reasons we've fell so in love with Sanyo's Eneloop line. Without question, the Eneloop rechargeable AA batteries are amongst the best and most reliable that money can buy, so whenever another Eneloop product pops out, it obviously catches our eye. Sanyo's branching out pretty severely with its latest device, and being that at least 3.5 members of the Engadget staff have strummed a six-string once or twice, we had to take a closer look at the Pedal Juice when given the chance. For those that missed last month's introduction, this pedal-sized block of energy is designed to provide 9V power to six or seven effects pedals, miniature amplifiers or electric drum pads (amongst other musical doodads). So, does this thing live up to the Eneloop reputation? Find out after the break. %Gallery-111994%

    A good roadie can be identified by two things: a wardrobe composed entirely of darks and bulging pockets full of batteries. Sanyo would like to let those tireless workers downsize to some slimmer black jeans with its new Pedal Juice battery pack, which is rocking a little Eneloop technology inside and can power a whole slew of daisy-chained devices. Charge it up for 3.5 hours and it'll provide 9V DC of output to whatever you like, powering a 10mA effects pedal for a whopping 50 hours. That's about 10 times longer than a simple 9V battery and, unlike one of those, the Pedal Juice will provide a constant 9V right up until it's dead. It even promises less electrical interference than using an AC adapter. All that for $149.99, which may sound like a lot for a battery pack, and it is, but real musicians know that success doesn't come cheap. %Gallery-108488%

    Rechargeable batteries keep a lot of toxic goop out of the world's landfills, but ones that drain themselves whilst just sitting there in the drawer aren't exactly perfect themselves. Sanyo licked that problem with its eneloop cells, thanks to their low self-discharge rates, and now the company is doing even better: boosting capacity. Sanyo will soon ship the eneloop XX battery in AA size, a 2500mAh cell that offers 25 percent more oomph than its predecessors. Even more important? The black and silver logo that serves as "a further testament to Sanyo's design strength." These up-rated and macho-designed batteries start shipping in Europe in December and, while no price has yet been assigned, given the number of times Sanyo mentions "professional" in its press release (six) they probably won't be cheap.

    Make no mistake, we're unabashed Eneloop rechargeable battery fanboys around here. How could we not be given our mobile lifestyle and obsessive need to keep all our toys juiced. As such, we're stoked by the announcement of a pair of Sanyo power packs: the Eneloop Mobile Booster (model KBC-L2BS) and Eneloop Stick Booster (KBC-D1BS). The Mobile Booster is a rechargeable slab of lithium-ion with a pair of built-in USB terminals (and microUSB adapter) capable of pushing a relatively hefty 1 Amp charge for about 2 hours (or 500mA for 4 hours if charging two device) to gear that requires that kind of suck... like the iPad. The battery pack can then be recharged over AC or a USB connection on your PC. The highly portable Stick Booster, meanwhile, ships with a pair of AA Eneloops -- so when the electrons cease to flow you can just swap out the dead batteries for a pair of fresh rechargeables. The Stick Booster is also an official Nintendo licensee so you can be sure that it'll charge your DSLite, DSi, or DSi LL (no mention of the 3DS). Look for these to ship October 21st in Japan.%Gallery-100758%

  • Apple Battery Charger gets official: a battery charger, only you know, better (update: hands-on)

    Apple's just slipped something into its iMac update press release that we didn't want to go unnoticed: a battery charger. Apple's AA battery-powered lineup now includes the wireless keyboard, the Magic Mouse (which seriously burns through the juice) and the Magic Trackpad, and for $29 you can score a dedicated charger for all that gear. The Apple Battery Charger comes with six long-lived NiMH rechargeable batteries which apparently have a lifetime of up to 10 years. Update: We just had a chance to get a quick hands-on with the little guy, and well, it's a battery charger. Apple tells us the charger has the lowest vampire power draw of any charger on the market -- the idea is for users to keep two batteries in each of their peripherals and two in the charger, so they can quickly swap out as the cells run out. Interestingly, the batteries are some of the only Apple products in recent memory that don't have an Apple logo on them -- they're just plain silver with "Rechargeable" printed on them. The charger itself has slightly nicer charging contacts than the usual spring-and-flap arrangement, and it features the same removable flippy-prong AC plug as Apple's laptop and iPad power adapters, so you can theoretically swap it for a longer power cord if you like. %Gallery-98293%

  • AA rechargeable battery shootout: Energizer, PowerGenix and Sanyo Eneloop

    If there's one thing that has become abundantly clear to us these past few months, it's that there's really no excuse to not invest in at least one set of rechargeable batteries if you find yourself chewing through more than a few on a regular basis. If you're an avid user of Apple's power-hungry Magic Mouse, Nintendo's oh-so-demanding Wii remote or one of the many professional camera flashes on the market, chances are you've considered buying stock in Duracell or Energizer based on how often you find yourself in the battery aisle. Quite a few devices have moved to proprietary rechargeables -- many of which can be rejuvenated over USB -- but for everything else, it's typically AA or bust. We tested out PowerGenix's NiZn cells late last year, and it wasn't long before we found ourselves in possession of two alternatives from Energizer and Sanyo. Care to see how all three of these stacked up against one another and those traditional non-rechargeables? Read on for more. %Gallery-92885%

  • Hitachi claims secret chemical formula will improve battery cathodes, double longevity

    Before lithium-ion batteries, portable gadgets were a nightmare, forcing road warriors and Discman-toting teens to either swap disposable cells or deal with rechargables that (with few exceptions) were tricky to recharge. Of course, Li-ion batteries also have a downside: as laptop and cell phone users have no doubt found out, they too become disposable before long. One reason why is that acid in the electrolyte can corrode the cathode material -- and now, Hitachi claims it's found a way to strengthen its own. Using an undisclosed combination of elements to replace some of the manganese used in the company's cathodes, Hitachi claims they can strengthen their crystalline configuration to resist acid, reduce cost, and best of all, double the usable life of a lithium-ion cell to about ten years. We've heard similar claims before, of course, with other battery manufacturers promising us twenty years, but it looks like this technology might make it out of the lab. NEDO, a Japanese government organization, has commissioned Hitachi to bring these batteries to life for industrial applications like wind farms. Cell phones, sadly, will have to wait.
