Msiwind9cellThat’s the question I have after getting a look at a third party 9-cell battery available for my MSI Wind. The 7200 mAh power pack runs around $115 and also lets your Wind run for nearly ten hours on a single charge. I haven’t seen any reports on the weight of the battery yet and it clearly causes the backside of the netbook to rise up, providing more of an angle to the typing surface.

Common sense tells me that this unit would weigh around 50% more than the 6-cell battery I currently have. While I’d have no qualms about ordering a second 6-cell battery if I could find one, the solution of carrying more battery cells is starting to get old. We continue to see hardware developments reduce the amount of required energy a device needs, but we’re still stagnating on battery technology in general. We’ve heard about fuel-cells and silver-zinc batteries for a while, but nothing has hit the market yet. Clearly, there’s demand for higher-powered and more efficient battery technology, so what’s the holdup?

  1. For me, it all comes down to this:
    1) Less than 10hrs is not sufficient for me
    2) Plugging in a power cord is less mobile than an heavy battery.

    Until netbooks and laptops reach a (real-world) battery life of about 10-12hrs, I think there will be a big market for extended batteries – even at the cost of mobility.

  2. The first battery to establish that unless you have a windlass you will be windless. :-)

  3. I think for me, the 9-cell would only become useful on something like a 10 hour flight and I needed the power. But the chances of that are slim these days. If I was taking a 10 hour flight, i think I’d be sleeping for most of it, and would be fine with the 6-cell which I currently have.

    I’d agree with Bob though, the powercord is less mobile than the battery. Which brings me to a complaint I have…these extra long cords are convenient, but super annoying and bulky! Would be nice to have the option of a super short power cord for traveling.

  4. The real problem is with density, the more potential energy you cram into something the more energy it contains. That is mostly a problem when something malfunctions i.e. batteries catching fire, with increasing the density you get explosive batteries. I saw a demonstration a while back on some of the batteries used by special forces that keep their electronics running for several days. But those batteries if placed in a camp fire have the explosive power of a stick of dynamite. Very cool to see but not something I would want to carry on my person or want other to take on a plane.

  5. At what point does a big battery defeat the purpose of mobility?

    Based on that picture, I’d say at that point right there.

    There’s no way I’d put a battery that size on a netbook sized device.

    As pointed out above, I’d rather schlep a horking big battery than have my machine catch fire due to a hastily-developed newfangled kind of battery !

    I don’t object to large-sized or even high-weighted batteries. I object to poorly designed geometries for those batters that make it obnoxiously uncomfortable to be mobile with them.

  8. Excellent point, GoodThings2Life.

    If they’d make the battery extend from the back, rather than the bottom, these things would be much more attractive.

  9. I like the slaps that attach at the bottom of the device, like Dell offers it now. I still use an old IBM Thinkpad X40 with a 8-cell battery that hardly sticks out and a battery slap at the bottom, gives me up to 11 hours with the screen brightness turned down and wifi off, perfect for typing on plane rides. I wouldn’t like a battery like the one in the picture.

  10. This is why I went to a Mac. At some point in the PC world, hardware designers though it was ok to design around a 4 cell battery pack. Almost no PC maker sells PC’s without “stick-out” battery packs that will net more than 2 hours of work time.

    Why is it so hard to make a 1″ thick laptop less than 7 lbs with the AC adapter and still get 4-5 hours of battery time?
