The Finch Formerly Known As Gold

Charge!

Toshiba has announced a new lithium-ion battery that can recharge to 80 percent of full capacity in one minute, compared with the hour or longer it takes for present-day batteries of otherwise similar formulation.

According to the company's press release, the new cell can handle up to 1000 charge/discharge cycles with only 1 percent loss of capacity, and can operate at temperatures from -40 to +45 degrees Celsius, making it suitable for motor-vehicle use.

I just hope they remember to make one that fits in my notebook computer.

I'll believe the performance when I see it. My previous notebook was a Toshiba and the original battery never came close to specs, even with power saving options engaged. I bought a replacement battery directly from Toshiba after a year or so and it performed exactly like the original.

The rest of the notebook performed OK though and the one warranty problem (CD) was very promptly repaired.

Even if they do, it'll probably cost more than the laptop is worth......

The battery in my current Toshiba Satellite dies at exactly 1:59 every time. At least it's consistent.

Hmmmm...wonder if this advance will play a role in automobiles, at some point...?

I can see it as the power source for a hybrid pretty easily; full-fledged electric cars still have other issues, but there's no theoretical reason they couldn't bolt a bunch of these into them.

am or pm?

Nothing to do with the actual time: it's the battery life, which never seems to vary from just under two hours. Of course, if I started it up at noon or midnight, it would die at 1:59 on the clock.
