Admit it, your 1150mAh stock Palm Pre battery is far less than stellar -- it's okay, we won't tell anyone. In fact, you can pick up an even larger, 1350mAh battery from Seidio that manages to keep the same physical proportions as its predecessor, meaning no dead giveaway / gaudy bulge the back of the phone. Ideally, that'd get ya an almost twenty percent bump in usage, but we doubt it pans out so nicely in field testing. Feel free to find out for yourself, it's on sale now for a cool $45.

While Apple may have moved on to selling the 4th generation iPod nano, consumer protection agencies are still focused on gen-1. For good reason too, apparently, as there's mounting evidence that those early white and black plastic players have a tendency to overheat, swell, and possibly burst into a nasty chemical fire. Responding to four formal consumer complaints made between December and June, the Korean Agency for Technology and Standards sent a request to Apple on June 25th recommending that Apple "aggressively" collects first generation iPod nano with Lithium Ion batteries made by the Chinese company ATL. Initially, Apple agreed to replace faulty units as they did in Japan upon request by the consumer. However, KATS is now reporting that Apple will recall the players under its own initiative making this the first formal iPod nano recall we can, uh, recall.

You know that fancy flat-panels can display more colors than the human eye / mind can even interpret, right? Thanks to our hard-wired limitations, a certain facet of boffins across the way are developing a method that would scale back the amount of colors used in an OLED screen in order to shave energy usage even further. Johnson Chuang of Simon Fraser University in British Columbia has worked with colleagues in order to conjure up sets of colors that "slash the power consumption of an OLED panel by up to 40 percent, with minimal effect on how people perceive an image." In theory, at least, this breakthrough could lead to longer battery life in cellphones, PMPs and all manners of portable devices. As Chuang puts it: "Say you're running low on battery and you want to use Google maps to get home; switching to an energy-aware color set could make your battery last longer." Don't pretend that doesn't interest you.

Energizer's Energi To Go catalog just keeps getting sweeter. After introducing a new range of XPAL battery chargers last month, the company is evidently gearing up to reveal what's likely to be its most convenient and altogether useful product yet. The USB clip you see above is designed to make contact with DSLR and camcorder batteries and provide juice via USB; in other words, it's like a portable, highly mobile DSLR battery charger. OhGizmo points out that you may need one of Energizer's USB-equipped battery packs to charge up the 7.4V cells, but at least we're still talking about a non-proprietary charging connector. Per usual, there's no mention of dollars and cents, but hopefully it'll be rolled out for less than a song here soon.

We won't bother detailing just how sophisticated the system is that's powering the wild whip you're peering at above. We won't bother mentioning just how many A123Systems batteries are installed, nor how intelligent the creator is. We won't bother wearing our jealously on our sleeves. What we will do, however, is point you after the break in order to have a look at just how exhilarating a ride in the LOLrio Cart (otherwise known as an electric go-kart) is. Harris Teeter, you getting all this?

We've been fans of Sanyo's rechargeable Eneloop batteries since they first entered the market in the lazy NiMH and NiCd days of 2005. We remember this because we, like Eneloops, don't suffer from the memory effect of our predecessors. Ok, ok, that date's in the press release but that doesn't change the fact that Eneloops will maintain their charge over time even when stored, ununsed in a drawer now does it? Anywho, Sanyo just announced its rechargeable Eneloop Lamp that serves to light your home when upright or your path when held like a flashlight -- automatically, just as soon as it passes the 90-degree mark. It also features a healing function that waxes a cool blue light into the tragic abyss of your misery and despair. The internal AAs recharge in about 12-hours when set atop the included induction charger. Fully charged, you can expect between 3- and 45-hours of white light, 12- to 16-hours of the blue stuff, and about 6 hours in flashlight mode. No price was given but it'll be on sale in Japan starting September 11th.

We've already seen some zinc-air batteries hit the market, and now it sounds like lithium-based cells will be the next type to use air as a cathode. The only problem? Those of you who were awake in 10th grade chemistry might remember that exposing lithium metal to water causes it to explode -- which is why a company called PolyPlus has partnered with the government to develop a unique waterproof lithium metal-air battery that keeps the boom-boom in but lets the buzzy-buzz out. The coating allows lithium ions to seep out while preventing water from getting in, and because the membrane protects the cell, the battery won't discharge in storage. If that sounds a little pie-in-the-sky, well, it is -- PolyPlus founder Steven Visco called lithium metal "the holy-grail battery material." Us, we're a little more skeptical, but we're loving the sounds of prototypes that deliver the juice of current laptop batteries at one-fifth the weight -- hook us up, boys.

Kodak's already taken some steps to cut down on counterfeiting of its batteries, and it looks like Panasonic is now taking some fairly drastic measures of it own, which could leave some users of its cameras a tad unhappy. Apparently, the company has determined that some third-party batteries amazingly don't meet its own rigid safety standards, so it's now released a new firmware update that can detect said batteries and prevent them from working. At the moment, that only includes cameras that use DMW-BCF10, DMW-BCG10, or DMW-BLB13 battery packs (some sixteen cameras in all), but it seems safe to assume that this'll soon be standard practice on all Panasonic cameras.

Remember that Miles Electric sedan we heard about last month? Yeah, well it's coming to California's shores next year. An all new car company, doing business under the name of Coda Automotive, has just been formed in order to bring said vehicle into production. The all-electric, four-door Coda won't break down any walls in the design department, but the $45,000 (mid-$30,000s after a $7,500 Federal tax credit and additional state incentives) whip sure sounds promising as an eco-friendly daily driver. Reportedly, it'll cruise for around 90 to 120 miles without needing a recharge, and the batteries within can be charged enough for a 40-mile commute in two hours. It'll also ship with a navigation system, Bluetooth, iPod support and power everything as standard, but sadly, there's no telling when it'll be sold outside of the The Golden State. Video promo is after the break.

We've seen Energizer dabble in portable charging solutions before, but we've yet to see it go all out like this. Thanks to a newfound partnership with XPAL Power, the company famous for making drum-toting bunnies famous has issued several new wares in its Energi To Go line. The rechargeable power packs and emergency chargers -- over ten of 'em in all -- will all ship by July of 2009 and will include devices for PMPs, PNDs, portable DVD players, netbooks and digicams. There's even an AP Charger that mounts your iPhone (à la mophie's Juice Pack Air), and the SP line consists only of solar-driven power packs designed to rejuvenated your iPod, camera and pretty much any other handheld device. There's no mention of price just yet, but as with anything Energizer, you can go ahead and brace for sticker shock.

Go on and file this one away in the folder of "awesome things that could, but won't ever happen." As the brilliant minds around the world figure out how to solve vicious diseases, move motorcars with peanut oil and send engineers to fix a telescope in outer space, we still can't buy a pack of AA cells that last longer than a month or two in our favorite toy. Some call it a limit of physics, some deem it a conspiracy. Whatever the case, we've no doubt whatsoever that a new silicon-containing carbon material -- designed by Dow Corning Toray to double the capacity of existing Li-ion batteries -- won't ever have a real impact in our lives. Of course, it's not like any consumer would actually benefit from having a netbook battery good for 16 hours, nor would wedding photographers enjoy being able to shoot 1,000 indoor shots without cracking the battery door open on their SB-600. No -- that's just absurd. C'mon Dow, prove us wrong here.

HP just recalled a hefty 70,000 laptop batteries earlier this month, but it looks like it still has a few more fires to put out, and it's now recalled another 15,000 batteries sold in China. No reports of any actual "flames / fire" this time around but, as with countless other recalls, the batteries are apparently prone to overheating, and can indeed pose a pesky fire hazard. Word of specific models affected is also a bit hard to come by at the moment, but the batteries were apparently used in laptops manufactured between late 2007 and early 2008, and include models sold under both the HP Pavilion and Compaq Presario brands. If that sounds like your laptop, you can get in touch with HP China for a free replacement battery.
