All about laptop batteries: Updated

By Asher Moses, CNET.com.au & Brian Nadel, CNET.com on 26 June 2006

Ever wondered why your portable device's battery doesn't last longer? We explain the technology behind battery power, and provide tips on how to maximise it.

The simple fact of notebook life is that systems simply don't run for as long on their batteries as we'd like -- even long-lived notebooks, such as Sony's VAIO VGN-TX27GP, last only 5.5 hours on a single battery.

To help you make smart decisions about the notebooks you buy and the way you use them, we demystify today's battery technologies and examine the fuel cell technology that might power your next notebook. We also provide 10 tips for getting the most out of your system's current battery, along with a glossary of key terms.

We can't make a battery last forever, but we can help to make sure that you get the most out of every electron.

    I would suggest the solution as using external laptop battery. I bought one from eBattery.com.au. ENB001 is one the best solution had even seen in my life. Pretty well designed battery with digital gauge and build-in usb port for $246. It works for me and may work for you too.

    NiCad, NiMH and Li-ion are all fundamentally different from one another and cannot be substituted unless the device has been pre-configured from the factory to accept more than one type of rechargeable battery. The difference between them stems from the fact that each type requires a different charging pattern to be properly recharged. Therefore, the portable device's charger must be properly configured to handle a given type of <a href="http://www.my-batteries.net/laptop-battery.htm>Laptop battery </a>

    The Sony <a href="http://www.batteryfast.com">laptop batteries</a> cells are known to be defective. Lenovo will not gurantee us that we have cells that are not defective. In fact they have confirmed that our Lenovo battery packs have the same battery cells that are know to be contaminated. I am very upset that Lenovo is not doing a similar recall of the known contaminated cells!
