Apple may have taken the time to officially reveal a new iMac, Mac Pro and 27" Cinema Display this morning, but two accessories that slipped under the radar are equally as interesting, if not more so. Scattered about the press releases for the new iMac and Mac Pro were mentions of a new Multi-Touch "Magic Trackpad," which is an all new input peripheral from Apple that's designed to bring some of the company's expertise in Multi-Touch to the desktop. Up until now, Multi-Touch has been reserved largely for touch panels and notebooks, but the new trackpad enables those same gestures to be translated onto the desktop. Basically, this is a trackpad right out of a MacBook Pro, but larger and equipped... Read more...
The next time you walk down the street and see some suit spazzing out, don't assume he's crazy (unless he's foaming at the mouth), maybe he's just recharging his digital camera, or any other electronic device that uses AA or AAA batteries. That's because the eggheads at Brother Industries Ltd. have put together vibration-powered generators capable of giving the company's prototype batteries a shot of juice when shaken. "The new generator will semi-permanently eliminate the need to replace batteries and contribute to reducing the amount of wastes," Brother Industries explains. Brother Industries' AA-size prototype with the generator and rechargeable battery installed in different cases. In their... Read more...
Earth Day was this week, and it seems that it was a much bigger deal in 2010 than in year's past. Maybe it had something to do with those tons of gallons of oil spilling off of the Gulf of Mexico (we're sure the Earth loved that), or maybe this is just what happens when everyone gets on the "green" bandwagon. Either way, PC Treasures and Digital Works Australia are definitely fans of the holiday, and they have joined forced not to bring back Captain Planet, but to bring the ReZap Battery Engineer to North America. Basically, this battery recharger does one better than most already on the market by adding life to standard batteries. The key word here is "standard," which is being used in place... Read more...
Let's face it: just about any gizmo worth using these days has a USB connector, and more often than not, it's actually charged over USB as well. But also, battery life has sunk in recent years as devices are made to be slimmer and hold less spacious batteries. The solution to this quandary? Sanyo's Eneloop Stick Booster, of course!For those unaware, the Eneloop line of rechargeable batteries have been around for a little while, and those that use them tend to swear by them. If you're alread on the Eneloop bandwagon, this product shouldn't be a tough sell. Basically, the Eneloop Stick Booster is a tube that holds a pair of AA Eneloop batteries. When your USB-related gizmo needs a boost, you simply... Read more...
Around here, there seems to be a never-ending debate surrounding batteries. You can't live with 'em, and you certainly can't live without 'em. Whether we're discussing just how disingenuous most battery life figures seem on modern day notebooks or just how great our lives would be if someone could develop an AA cell that lasted longer than a blink of an eye, we're pretty sure the topic won't ever grow cold.Helping to prove our point today is Sony, who has just launched a new type of lithium ion secondary battery that combines high-power and long-life performance by using olivine-type lithium iron phosphate as the cathode material. We know, that's a lot of technobabble all at once, but there's... Read more...
Batteries seem to be a growing topic of discussion here at HotHardare. From netbooks with increasingly large cells to debates over the legitimacy of notebook battery life figures, it's safe to say that longevity away from the plug is an important matter for true PC enthusiasts. To that end, we couldn't help but take notice when we came across a new development that could lead to thinner, more portable batteries for all of our mobile electronics. Developed by a research team led by Dr. Reinhard Baumann of the Fraunhofer Research Institution for Electronic Nano Systems ENAS in Chemnitz, a newfangled printable battery is said be cost effective and able to be produced on a large scale. We needn't... Read more...
It's been about two years since millions of Sony notebook batteries across many different OEM lines were recalled, due to overheating --- and fire problems. We assume you haven't forgotten about that, because here we are again. Here's hoping this isn't the beginning of another long list of recalls involving Sony batteries. At any rate, the US Consumer Product Safety Commission issued the recall on Thursday. According to the recall, There have been 19 reports of the batteries overheating, including 17 reports of flames/fire (10 resulting in minor property damage). Two consumers experienced minor burns.Check out the full list below. It's pretty long, bug only consists of about 35,000 batteries... Read more...
All those of you who are using generic, and in particular, high-capacity batteries with your Eee should watch out.  It seems you might have an explosive combination. Second- and third-tier battery makers in China have begun to manufacture batteries designed to be used with the Eee PC. Some vendors are offering batteries with capacities up to 10,400mAh, which can support up to 5.5 hours of usage, priced around 500-600 RMB (US$71-86), according to channel vendors. However, reports claim that one of these "high-capacity" batteries recently overheated during charging, and eventually exploded causing damage to the Eee PC. According to the reports, Asustek has refused to repair the PC, but Asustek... Read more...
There was a fire in LG Chem's plant in South Korea in March of this year. "So what?"  you might ask. Well, that plant makes lithium-ion batteries, and that's helping to limit the supply of laptop computers. "I think maybe the battery shortage may hurt every brand," said J.T. Wang, chairman of Acer, at the company's investor conference two weeks ago.But the head of the world's largest independent notebook battery maker, Simplo Technology, said he expects the lithium-ion supply to return to normal in the third quarter and allow battery makers to substantially increase production. "The LG Chem problem has had a big impact on supplies, but we're working with customers and they understand," said... Read more...
If you've been stashing extra lithium batteries in your luggage when flying, the Transportation Department would like a word with you.  Wary of short circuits that could cause a fire, they're limiting the amount you can transport, and specifying the type of packaging required for the little lithium friends you carry to keep your electronic devices ready for action.The ban affects shipments of non-rechargeable lithium batteries, such as those made by Energizer Holdings Inc. and Procter & Gamble Co.'s Duracell brand."Doing something as simple as keeping a spare battery in its original retail packaging or a plastic zip-lock bag will prevent unintentional short-circuiting and fires," Krista...

Some very clever people at Stanford University have devised away to modify lithium-ion batteries with silicon nanowires to expand the capacity of the batteries and allow them to deliver electricity for ten times as long as they currently do before recharging. "It's not a small improvement," Cui said. "It's a revolutionary development."The breakthrough is described in a paper, "High-performance lithium battery anodes using silicon nanowires," published online Dec. 16 in Nature Nanotechnology, written by Cui, his graduate chemistry student Candace Chan and five others.The greatly expanded storage capacity could make Li-ion batteries attractive to electric car manufacturers. Cui suggested that they... Read more...
Despite competitors having talking points about how the iPhone battery isn't replaceable, that's not entirely the case.  It's true that the user isn't able to buy a battery and  swap it out on the road as they can with many existing phones, but Apple can do it for you, for a fee of $85.95 plus applicable taxes: "If your iPhone requires service only because the battery's ability to hold an electrical charge has diminished, Apple will repair your iPhone for a service fee of $79, plus $6.95 shipping. Be sure to follow these instructions for optimizing battery life and troubleshooting battery charging issues before submitting your iPhone for battery replacement." Other... Read more...
Computer maker Gateway has voluntarily recalled about 14,000 lithium-ion battery packs, sold as primary or spare power supplies for some of their laptop computers, because they pose an overheating and fire hazard.  The Irvine, Calif., computer maker said the affected battery packs were shipped as the primary or spare battery pack for Gateway 400VTX and 450ROG series notebooks. They were sold during a three-month period from May 2003 to August 2003 in the U.S. through Gateway's Web site and its Gateway Country stores. Gateway said it will replace affected battery packs at no cost to the customer. It did not identify the maker of the recalled battery packs. Last year, the... Read more...
Scientists at Waseda University in Japan have come up with a nifty battery. It's made from polymers, it's only 200 nanometers thick, and it's flexible. Peter Skabara, an expert in electroactive materials at the University of Strathclyde, UK, praised the high stability and fabrication strategy of the polymer-based battery. 'The plastic battery plays a part in ensuring that organic device technologies can function in thin film, flexible form as a complete package,' said Skabara. 'However, these materials will not give slow energy release, which limits them to capacitor applications,' he continued. 'The polymers can undergo rapid charging/discharging... Read more...
