Acer: No Major Laptop Battery Improvement Coming

Jim Wong, president of IT products at Acer Incorporated, believes that notebook battery safety (think overheating Sony fiasco) is the main reason why fuel cells and other advanced technologies that can be used as batteries in notebooks won't likely be available for years. Electricity is generated by chemical reactions inside a battery, which produces heat as a byproduct. With so much chemistry involved, a lot more product testing is required, therefore battery technology progresses more slowly, Wong said. "The lithium-ion materials used in batteries today were discovered 30 to 40 years ago."

Fuel cells are promising, but the technology isn't ready yet, and an infrastructure needs to be in place before the technology can be widely used. Not only would fuel packets or refueling stations be needed for mass adoption of the technology in laptops, they would also need to be approved by aviation officials for use on airplanes. The battery issue is gaining more importance recently because the new era of multimedia laptops threatens to shorten battery life. "High definition is a most formidable enemy to battery life," said Wong. The power needed for HD DVD and Blu-ray Disc players in notebooks can't simply be offset by bigger batteries and power management technology aimed at shutting off parts of the machine that aren't immediately being used.

The power needed for HD DVD and Blu-ray Disc players in notebooks can’t simply be offset by bigger batteries and power management technology aimed at shutting off parts of the machine that aren't immediately being used.

And i ask why not? Every laptop user know that they have to make compromises. More battery time vs more movie,music,games...

Every action as it's cost, an hdvd drive or blueray drive are but componant. if they are not working they dont drain the battery it's as easy as that.

Who is this guy and where was he when laptop came equiped with cdrom drive, with dvd ?

Batteries didn't take 30-40 years to become what they are today because of safety. It took that long because long life batteries weren't that needed and weren't in demand. What we had was sufficient. Today it isn't.

That is true. In addition, contrary to what Mr. Wong says, battery chemistries do not need such vast amounts of testing that it will take decades to properly test them; they only need all potential safety issues to be adequately addressed and upon that being done, even the most rigorous testing would only take a few years.

Wiki I suggest you go read up on fuel cells. Nobody said petrol/diesel/anything refined from oil. Hydrogen fuel cells for instance are receiving lots of attention nowadays for car-purposes if I'm not mistaken.

You're right about the "fuel" used in the fuel cells, but hydrogen is the secondary fuel which in itself can't reduce the consumption of fossil fuel.

They haven't tested fuel enough for it to be inside our batteries.
Plus, no matter how efficient they think fuel is, I don't see it as the way to go. We're running out of it!

Yeah, but you would ONLY be able to turn on your laptop if you're in almighty USA. Otherwise the laptop will produce a terrorist alert and an e-sniper will shoot you in the head.

That's not even remotely funny, there's nothing wrong with being safe versus being sorry.
