    The actual life of a laptop battery will vary with computer usage habits. For most users, it is not uncommon to experience differences in battery life, of anywhere from just under one hour to over two hours in each sitting. If you are experiencing shorter battery life cycles, say 10 to 15 minutes, it may not yet be time to order that new battery.

    There are several factors to take into consideration when determining if the time has come to replace your battery. This information may also apply to that new battery that you have recently purchased, that has been giving you fits. take a look at what you should expect from your battery's life cycle.

    NiMH batteries usually last 1.5 to 2.5 hours.

    LiION batteries usually last 2.0 to 3.0 hours.

    These are average results and the results will vary greatly depending on your system's conservation settings, the temperature of the room and the climate that you are operating your computer in. As a general rule, your Lithium Ion battery will last much longer than your standard Nickel Metal Hydride battery.

    The more you use physical devices --- which require more electricity to operate --- the more of the battery's power you can expect to consume. The devices that create a larger power drain are the hard drive, the floppy drive and the CD-ROM.

    When the computer is able to use its physical memory resources to store information, the computer will use less of the battery's power, since the process is mostly electrical in nature.

    As far as audio devices are concerned, speakers require electricity to run and the software that is responsible for producing the sound does so by processing information. The display panel consumes electricity as well. In fact, the brighter the screen appears, the more electricity that it is consuming. You may turn down the brightness on the screen, thereby conserving more electricity than you may have considered possible. And when considering the battery drain caused by video devices, don't forget the effect that graphics programs will have on your system. Video applications can have an intense effect on your electrical needs, due to its usage of computation, calculations and virtual memory.

    well umm i have that problem sometimes cause mine is always plugged in. You should run it through one charge cycle a month at the minimum. This means let it run to wear the computer says charge the battery then charge it. It could also be becaue You have your screen on really bright and volume on and are running mulitiple applications. this will burn your battery quick especialy the volume and screen brightness. I would recomend getting a better battery and using the one you have now as a back up battery.

    A battery has a memory. Often times the first charge will determine the length of charges thereafter. My laptop last about a half hour but the battery is old.

    I trust Kenn N. The battery ought to be exercised via being run down & then recharged, preserving in a relentless state of being charged will develope a "reminiscence"; f'rinstance, in case you recharge a battery whilst that is basically discharged 10%, finally that is going to basically settle for a ten% fee. some laptops, certainly maximum, so some distance as I remember, could properly be run on mains with out the battery in - that's the respond for capability-hungry apps like video games & streaming video. i could seek for a sparkling battery, provide it an entire fee and in destiny basically use it whilst out & approximately. and then run it precise down till now recharging.

    same thing happens with cell phones, psps and other portable things, most likely its due to the fact that you overcharge your battery that makes it die out faster make sure that when you get a new battery you charge it only for the appropriate time, not the whole night through

    I had the same time constraints with my Gateway. It seems like they should last longer.

    As long as I 'turned down' the backlight on the screen, did not access drives (like CD/DVD) and did nothing that used the CPU alot I could get it to last maybe 30 minutes longer. It all seems to depend on how much power your laptop needs to suck up.

    Sound's like a bad battery or it's just not sufficient enough for the laptop
