As much as you convince yourself that you’re living in the future, or at least a pretty sophisticated present, the batteries say otherwise. Open up an iPhone or MacBook and you’re greeted by a fairly large battery that occupies space and adds to the device’s weight.
This may be about to change, as new research is suggesting that carbon nanotube technologies may be the key to implementing flexible batteries and supercapacitors capable of shrinking down devices even further.
According to Ars Technica, researchers at Rensselaer Polytechnica Institute and MIT have developed a new material that can eliminate several of the old constraints within a battery, especially where the need to create two electrode layers and two charge-holding layers with an insulating layer in the middle and the lack of flexibility this historically provides.

On Tuesday, FreshBattery announced a new Legacy line of batteries. The units are designed to provide batteries for laptop models that have been discontinued for three to five years, including older PowerBooks and iBooks.
According to Macworld News, the company claims that the batteries are designed to meet or exceed the original manufacturer’s specifications. In the case of a Legacy battery for an original PowerBook G4, FreshBattery has substituted the original 3600 mAH cells with 4400 mAH cells, resulting in a battery that adds an additional 40 minutes of run time between charges.
FreshBattery currently produces a battery range that covers the original “Clamshell” iBook G3s and goes back as far as the Wall Street and Pismo-era G3 PowerBooks. The Legacy battery line is currently priced under US$100 and available immediately.

As much as you may like your Mac laptop, things will occasionally go wrong. A Japanese couple living in Tokyo are filing suit against Apple and Sony regarding a PowerBook G4 battery that burst into flames in April of 2006.
According to the International Herald Tribune, the couple is suing for “over” two million Yen (about US$16,700) in damages. The suit alleges that the man suffered burns to his finger while using the laptop an his wife endured mental distress due to the incident.
The battery comes from a batch of more than 10-million Sony-made notebook batteries that were recalled in 2006. Sony has stated that battery problems were caused by microscopic metal particles insider the battery that caused the unit to short circuit.
Since the recall, Sony has stated that it will improve battery design, production and inspection methods to prevent a recurrence of fires in their batteries.

Getting The Most Out of Your Laptop Battery

Anyone who has purchased an Apple laptop knows that the battery life is significant. I specifically remember getting four hours of life (full screen brightness) with my first G4 Powerbook. As time advances, the battery, processor, and electronic technology grows; and with it comes the ability to produce a portable that is more efficient and energy conservative, yet still has the performance that consumers require.

As time with your laptop advances however, the battery on your system may begin to lose its charging capabilities. What was once four hours of life, turns into three and a half, then to two and a half, and so on and so on. Throughout your system life, the greater portion of the time you will never use your laptop until the battery is empty. More or less you will use it for a little, then plug it back in, take it off, plug in again and so forth. The process of doing this can miss-calibrate the battery to the point where it will not allow maximum storage capability and lower your battery life.

MacMerc.com has a full story and updated picture (via way of flickr) of a MacBook Pro battery swelling far beyond any size it should have originally been.
The battery is a model A1175 that should have been exchanged when Apple began its program in response to overheating and swelling found in the MacBook Pro battery series earlier this year.
Apple states that there’s no physical danger from using the swollen batteries and it’s still safe to use the batteries until a replacement unit arrives from the company.
If you have any further information or comments about this issue, let us know.

Hitachi said on Friday it will recall 16,000 batteries made by Sony for laptop computers, joining a growing list of PC makers recalling Sony batteries.

Hitachi is in talks with Sony about who will foot the bill to replace the lithium-ion batteries, but the number is too small to have any impact on Hitachi earnings, Hitachi spokesman Masayuki Takeuchi said.

The batteries were used mostly in laptops shipped to businesses, most of which are in Japan, he said.

The onboard use of Apple and Dell laptops containing batteries was banned recently by the airline, after the companies recalled of more than five million batteries because of a risk of overheating.

“Customers wishing to use an Apple or Dell laptop on board can only do so once the laptop battery serial number has been checked by a member of the Cabin Crew,” the company states on its website. “If the battery is permitted for use, the laptop may be used as normal on board, with no further restrictions.”
