We've seen some very sophisticated 3D-printed objects recently, but never a tiny 3D-printed battery -- one that's as small as a grain of sand, no less.

A group of U.S. and Korean researchers has managed to print a lithium-ion microbattery that can fit on the head of a pin.

Although it weighs less than 100 micrograms, it can store as much power per gram as larger Li-ion batteries used in laptops or electric vehicles. It could even power tiny robots or medical devices. … Read more

After a U.S. government agency received 13 reports of battery fires, including one that caused a "serious burn" to the user's leg, Best Buy has decided to recall thousands of replacement batteries for Apple's MacBook Pro laptops.

The U.S. Consumer Product Safety Commission announced Wednesday that "consumers should stop using this product" because "the battery can catch fire while charging." The culprit product is ATG lithium-ion batteries and Best Buy is recalling about 5,100 of them.

Those batteries being recalled are both the black and white ATG replacement batteries … Read more

For the past couple of months, prospective MacBook buyers, especially those looking for a slim MacBook Air, have been holding off on purchases, waiting to see what Apple had in store for its annual WWDC keynote.

While the new 11-inch and 13-inch Airs look and feel a lot like the previous couple of generations, the internal components have been upgraded with new, and incredibly energy efficient, CPUs, leading to battery life scores in excess of Apple's estimated 12 hours for the 13-inch version.

Because of that great battery life, you can bet that plenty of new MacBooks were ordered … Read more

AT&T is deploying solar-powered charging stations to help keep smartphones and other mobile gadgets juiced up in parks throughout New York.

The 25 stations, which each feature a microUSB, iPhone 4, and iPhone 5 plugs, as well as USB ports for other devices, are being set up in various parks this summer and offer a free recharge. They can be found this week in Riverside Park on the west side of Manhattan, in Union Square, and in Brooklyn Bridge Park, with more locations to come this summer.

The Street Charge project, which is still in its trial phase, … Read more

Cosmos System Care Free is touted as your all-in-one maintenance tool to keep your computer system healthy and clean. Indeed, when you first download the program, you are offered the chance for an immediate scan. However, while this program seems to be wide in scope, the free version only offers to scan your computer for problems; it doesn't fix them.

Cosmos System Care Free took more than 35 minutes to download, extract, and install on a dual processing system. The program scans for security problems including privacy issues, includes a file decryptor and encryptor, and backs up or restores … Read more

I first encountered the MyCharge Peak 6000 at this year's Consumer Electronics Show. Since then it has become my most prized travel accessory. I literally never leave home (for a trip) without it.

Why am I so enamored with something as basic as a mobile charger? Simple: the Peak 6000 does right what every other mobile charger does wrong.

For starters, it packs a 6,000mAh battery, which can recharge an average smartphone three to four times. Even better, you recharge the Peak's battery by plugging the entire unit right into an AC outlet. Its fold-up wall prongs … Read more

We've all heard stories about exploding cell phone and laptop batteries. A person is just walking down the street with his phone in his pocket and next thing he know his pants are ablaze.

The specific culprit batteries that cause such fiery incidents are lithium-ion batteries, which are known to have issues with heat. So, why can't there be chargeable batteries that are immune to overheating? There may be.

The Department of Energy's Oak Ridge National Laboratory (ORNL) has been working on new technology that looks to replace lithium-ion batteries. The lab has designed and tested a … Read more

How serious is Intel about battery life on its next processor? Very.

On Thursday, the world's largest chipmaker hauled out two chip experts to brief journalists on the ways Intel's fourth-generation core processor, aka Haswell, reduces power consumption and boosts battery life.

Intel is claiming a 50 percent improvement in battery life for devices using Haswell compared to the current Ivy Bridge silicon.

The chip will be officially introduced on June 3 and is expected to power future Windows, Apple, and Chrome OS computers.

The information below was provided by Rani N. Borkar, general manager, Intel Architecture Development … Read more

One thing I learned during my recent travels is that you can never have enough juice for your mobile gadgets. For example, if you're relying on your smartphone for GPS navigation in an unfamiliar city, you don't need the added stress of a low or dead battery.

Solution: pack a power pack. Like this one: Tumbletrade.com has a 12,000mAh mobile battery pack for $19.99, shipped. It includes everything you need to charge virtually any mobile device -- tablets included.

Update: Sorry, folks, this sold out almost immediately after I posted. When I ordered, five colors … Read more
