Our CNET Labs have just published the results of their Zune 80 audio-only battery drains and the numbers are somewhat disappointing. Microsoft rated the Zune 80 for 30 hours of audio playback with the Wi-Fi feature turned off. Lab testing revealed that the Zune 80 is realistically capable of 22 hours of audio playback with the Wi-Fi feature turned off, or 18.5 hours with the Wi-Fi feature enabled.
I fly internationally at least once per quarter. Given that flight time tends to be some of my most productive time, I need to ensure I have enough juice to get me over the Atlantic without missing a beat on email or, even more importantly, that Arsenal match I previously ripped to my Mac's hard drive with Elgato's EyeTV 250.
I used to use Electrovaya's PowerPad, but it doesn't (or didn't) support the MacBook Pro. So when I started looking around for a replacement, I discovered Batterygeek's Portable Power Station. It's bulkier than the Electrovaya battery, though more compact, and doesn't last as long (eight or nine hours, depending on how CPU-intensive my activity, compared to 10 to 14 hours). Having said that, Batterygeek has come out with new models that last as long, if not longer, than Electrovaya's (one goes for over 20 hours).… Read more
We're still waiting for Sony to hurry up and develop that sugar-powered battery for our mobile phones, but something like this might have to suffice in the meantime.
Philips is developing a handset for the Asian market that it says will provide 17 hours of talk time on a single charge and, on standby, will last for two months, according to SCI FI Tech. And it doesn't look like one of those one of those industrial-strength survival radios either.

Clean tech company M2E Power on Friday said it has raised money to commercialize battery technology that converts motion to electrical energy.
The $8 million series A round was led by OVP Venture Partners and included money from @Ventures, Highway 12 Ventures, and existing investors. The investment will be used to expand research and development and build initial products.
The company's mission, in essence, is to apply the long-understood Faraday Principle--that putting a conductor near a magnetic field will produce voltage--to 21st century applications.
Its initial target is to create a D-size battery for the military and then … Read more
Sony's biotech battery has a sweet tooth. It sups on glucose for energy (much like some of us) converting the sugar within beverages such as fruit juice and even Pocari Sweat into electricity.
A four-cell array is reportedly capable of generating up to 50mW of power, enough for small devices at the moment. For a glimpse into the future of alternative power cells, check out the video of the battery seen powering a desk fan and speakers attached to a Walkman, after being juiced up on a sugar solution.

An injection of graphite foam is giving new life to the venerable lead acid battery, according to Firefly Energy.
The Peoria, Ill.-based company has come up with a way to coat the membrane, a fan-like lead lattice that allows the battery to generate electrons, with graphite foam. This change results in a more efficient battery that can extract more electricity from the electrolyte, release more electricity per charge, and endure more charging cycles. The battery also will last longer. The foam gives the membrane a larger surface area for reactions.
Firefly's Oasis batteries are designed for long-haul trucks. … Read more
There are a lot of people who are convinced that established automakers and oil companies, along with some support from dealers, conspired together to kill electric cars back in the '90s.
One of the most repeated points they try to make is that General Motors only leased its EV1 electric car to consumers. The theory is that the lease existed so that GM could pull them back, in case people really liked the cars.
When was the last time a cell phone came to market with standard alkaline batteries? Sanyo has a new phone for Japanese consumers that not only bucks trends in power sources but also in appearance, with a cylindrical canister design that sports braille-like keys.
Dressed in that signature Cupertino white we all love, this is one phone that knuckles down to barebone basics to wring the most charge out of a single AA Sanyo Eneloop battery, according to Japan Today. So no 3G, no camera, no MP3 player, no SMS and not even an LCD screen (gasp!). All those sacrifices … Read more
MacBook Pro owners are apparently having trouble supplying power to their computers both from the battery and from the wall.
AppleInsider is reporting that Apple is getting ready to introduce new 85-watt MagSafe adapters for MacBook Pros following a litany of complaints about fraying cables on the adapters. When they were first introduced, most customers liked the idea of flexible cables that would detach from the computer if subjected to excessive stress, preventing your nice laptop from flying across the floor of the coffee shop when somebody trips over the cord.
However, the flexibility of the power cable has caused … Read more
It's good to see battery manufacturers improving their cells for use with today's more energy-needy gadgets. Following in Sanyo's Eneloop footsteps is the Duracell bunny. Yes, the original hare which predates Energizer's fluffy pink one.
And the former has even more reason to beat its own bass drum. It now offers (for a premium, mind you) pre-charged NiMH batteries. That's good news for gadget owners because it means you no longer have to tether those rechargeables overnight to the mains to season them first. Now you just pop them in straightaway to use.
Plus these … Read more
