    Potential Market for Plug-in Hybrids

    A new study shows that when consumers understand what plug-in hybrids are, they want them. The vehicles, which have large onboard batteries, can be recharged overnight by plugging them in, storing enough electricity to power daily commutes. For longer distances, a gasoline engine kicks in, assisting the electric motor and recharging the battery. The major automakers do not yet offer plug-in hybrids, but several are developing them. For those consumers who can't wait, a handful of companies offer conversion kits for conventional hybrids.

    Of the more than 3,000 consumers asked if they would consider buying a "grid-connected hybrid," the term used for plug-in hybrids in the survey, only 24 percent said that they would,dell latitude c610 battery, according to the survey by Synovate Motoresearch. But when they were told what such a car could do, that figure nearly tripled, to 64 percent. That's well above the percentage of people who would consider buying an ordinary hybrid, like the Toyota Prius, which doesn't have extended battery-powered range. Scott Miller, the CEO of Synovate Motoresearch, presented the survey's results this week at the Advanced Automotive Battery Conference in Long Beach, CA.

    The results suggest that consumers like the idea of the plug-in hybrid--but that so far,dell latitude c640 battery , car companies are doing a lousy job of getting the word out. That's not the case with flex-fuel vehicles, though. These cars, which can burn either gasoline or a mixture of 85 percent ethanol, scored high on the desirability charts--that is, until consumers were told more about them. Flex-fuel vehicles have been the subject of heavy promotion by automakers. But the marketing campaigns have fallen short of providing all the details: consumers thought that flex-fuel improved fuel economy, Miller said. Actually, the opposite is true. Ethanol contains much less energy than gasoline does, so miles per gallon will be significantly lower, as will range on a tank of gas. When consumers were told this, the percentage of people who would consider buying the cars dropped from 52 to 33 percent.

    It remains to be seen if the desirability of plug-ins is enough to overcome their steep price tag. They could cost thousands of dollars more than a conventional hybrid, which already comes at a premium. Still,dell latitude c800 battery,dell latitude cpi battery consumers are willing to shell out thousands of dollars more for SUVs than for minivans because of their perceived advantages. So if the word gets out and the cars get built, plug-ins might just be the next big thing.

    Keep the Power Flowing

    The recent laptop battery recalls, due to the potential risk of overheating or fire, have inconvenienced millions of mobile professionals. But lithium ion batteries--widely used to power today's laptops--are here to stay, at least for the foreseeable future.

    I recently offered tips on how to safely handle lithium ion batteries to minimize the already minimal risks of overheating or fire. This week I've got advice on keeping your notebook's lithium ion battery in top condition and powering your portable PC as long as possible.

    Use It or Lose It

    If unused for long periods of time, lithium ion dell laptop battery can very slowly lose their capacity to hold a charge. Fortunately, lithium ion batteries hold their charge better over time than other rechargeables, including nickel cadmium and nickel metal hydride. But you want your spare to be ready when you need it, so if you've got an extra battery for your notebook, use and then recharge it on occasion to keep it ready to go.

    Shut Down Completely

    When your notebook is running on battery power, there are things you can do to extend its charge. For one thing, when you're finished working, shutting down your computer instead of putting it into Stand By or Hibernate modes preserves battery power. Though Stand By and Hibernate enable you to restart quickly, both modes continue to draw power from your battery. (Hibernate uses less juice than Stand By, however.)

    Turn Off Wi-Fi, Bluetooth and Cellular Modems

    Always turn off Wi-Fi, Bluetooth, and cellular modems when they're not needed. These wireless network technologies can be a significant drain on your laptop battery's charge. Many newer notebooks have buttons to turn wireless connections on and off. You can also go to Start, Connect To, "Show all connections," then select the connection you want to enable or disable.

    Remove Discs and Devices

    When they're not needed, remove CDs, DVDs, flash media cards, PC Cards, ExpressCards, and connected peripherals. When you have media inserted in a computer drive, such as a disc in the CD/DVD drive, the computer continues to try and communicate with that drive. And everything a computer does--including those communication attempts--is a drain on its battery power.

    Tweak Power Settings

    Your notebook's display is one of its main battery drains. Thankfully, Windows XP notebooks include a utility for adjusting display and other settings that can affect your battery charge.

    But here's a caveat: Don't get too ambitious with your power conservation settings. Your notebook must expend power every time the hard drive and monitor are awakened from their sleep. So for maximum efficiency, make your settings fit your usage patterns. As a general rule of thumb, I recommend that when you're running on battery power you opt to have the hard disk turn off after about 20 minutes and the monitor after about 10 minutes.

    Adjust Screen Brightness

    You can also save battery power by lowering your laptop screen's brightness. In most cases, this is done using a combination of function keys. For example, on my HP Pavilion dv1000, I hold down the Fn and the F7 keys together to decrease screen brightness and the Fn and F8 keys to increase it. You may be surprised to find that your display is quite comfortable to view at a lower brightness setting than the default.

    Get a Long-Life Battery

    Many notebook vendors now offer an option for an extended-life battery. Usually, these batteries are heavier, bulkier, and more costly than standard batteries. But they can significantly extend the time your notebook operates away from a wall socket.

    Consider a Notebook Battery Booster

    Some third-party power products are available that can significantly extend your notebook's battery life.

    Xantrex's XPower Powersource Mobile 100 ($130) is like carrying around a wall socket. Plug the AC adapter of your notebook (or other device) into this power brick, and the Powersource's internal battery will keep the notebook running for about 2 hours, according to my informal tests. The Powersource also lets you charge USB devices. And it could come in extremely handy during a power outage. The downside: At 2.4 lbs., the Powersource weighs nearly as much as some ultraportable notebooks. [Correction: The Powersource Mobile 100 actually weighs about a pound, as the Xantrex rep informed us shortly after this article went live. --Editor]
