    Battery Information :

     

    == I. Storing batteries  :

     

    Charge the battery to its full charge (capacity) and then store it. Batteries should not be stored with less charge or no charge. This is because the shelf  life of the notebook battery without charge is only about 30 days, after which the battery will become nonfunctional. So, it is necessary to charge the battery  fully and then store it in a safe place.

     

    == II. General Information :

     

    You can remove the battery and store it in a cool location while using the laptop on AC power. However, this process may not really extend the life of the battery.

     

    If the battery is not used for too many days it may go dead. There is every possibility that it may not work again. To avoid such instances, I recommend you even use the Notebook on battery so that battery charge is drained out and later recharged.

     

    You can keep the battery inside the laptop even when using the notebook on AC power.  Once the battery is completely charged, the voltage to the internal battery charger is cut off automatically. However, you may need to use the notebook twice or thrice in week on the battery power. This will ensure the battery charging and discharging. When using the notebook on the battery, use the notebook till the battery is completed out of charge.

     

    Next, it is recommend to shut down the computer when not in use for a long time.  Say more then 24 hours. If you are away from the laptop for a couple of hours, hibernate the unit or allow it to go to sleep mode. This will extend the battery life and the laptop as well.

     

    == III. How to operate battery:

     

    Next, when the computer is operated on battery power it is not necessary that you need to run the notebook until the indicator shows little amount

    of charge left.

     

    You can use as per your wish. I mean to say you can use the notebook on battery power for little amount of time or until the charge gets near completion. This does not affect the notebook or the battery in any way. Please be assured of this.

     

    Last, the battery will not harmed in any way if the computer is plugged into the AC power as the battery receives negligible amount of voltage. Please be

    assured of this. But for at least fifteen days discharge the battery completely and then recharge it again to full capacity. This will increase the average battery life longer.

    ==Battery Do Nots:

     

    1) Do not short-circuit a battery. A short-circuit may cause damage to the battery.

    2) Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive.

    3) Do not expose the battery to moisture or rain.

    4) Keep the battery away from fire or other sources of extreme heat. Do not incinerate. Exposure of batteries to extreme heat may result in an explosion.

    5) Do not throw away or dispose of your battery with household waste. Please recycle all batteries, as they contain chemicals which are harmful to the environment.

    6) Do not carry loose batteries in a bag or box with metal objects like coins, paper clips and hair pins, etc. This may short circuit the battery, generating high heat.

    7) Do not mix old and new batteries, or mix different types of batteries. This can cause rupture or leakage, resulting in personal injury or property damage.

     

    == Tips to ensure optimal battery life:

     

    1) Use the AC adapter whenever possible, but not all the time.

    2) Set the Windows Power Management settings to maximum savings.

    3) Lower the brightness setting on the screen backlight.

    4) Disconnect any unused devices (e.g., modems, wireless LAN cards, USB devices) when not needed.

    5) Disable Auto Insert Notification on the CD-ROM.

    6) Disable automatic formatters, spell checkers, auto recalculate and auto save features.

    7) Add more RAM memory to lower disk access time.

    8) If you have a backup battery, use it in rotation with the current battery.

    9) Use the Suspend or Hibernate feature when taking a break.

    10) Fully drain and recharge the battery every couple of months, this helps to recalibrate the smart electronics even if the cells are fine.

    11) Minimize the number of programs running at the same time.

    12) Check the power save settings under the BIOS. If this is not enabled then the Windows Power Management settings may not work properly.

    13) If you are taking the battery out to store it, make sure it has at least 40 - 50% charge. DO NOT fully charge it or discharge it before storage.

    14) Use less processor intensive programs when possible (e.g. WordPad instead of Word).

    15) Minimize game play and DVD viewing.

    16) Clean the battery contacts with a cotton swab and rubbing alcohol. This helps maintain a good connection between the battery and the device.

    =================================================

    Battery Life + Vista

     

    I would like to inform you that the battery operating time will be less than compared to the time that lasts in Windows XP Operating System. This is because the graphics features used in Windows Vista consume more power.

     

    The discharge time depends on the features you are using while on battery power. For example, if you are playing a DVD and are connected on a wireless network, your battery life will be shorter than normal. If you are just reading or editing a file or answering e-mail on a wired network connection, you will experience maximum battery life. Please note that maximum discharge time will shorten over time, as the storage capacity naturally decays.

     

    == Tips for maximizing discharge time of battery:

     

    1) Lower the brightness on the display.

    2) Check the Power saver setting in Power Options.

    3) Remove the battery from the notebook PC when it is not being used or charged for a long period

    4) Store the battery in a cool dry location.

     

    == Checking the Status of the Battery:

     

    Please refer to the below weblink for information on checking the Status of the Battery:

    Battery Life Improved:

     

    Daniel, let me inform you that Battery life increases if you do not watch movies, play games on Battery Power. However, you can perform the same with AC Adapter plugged so that the Battery Life of your Notebook will be increased. Please refer to the information relating to battery maintenance.

     

    Regarding your query, I would  like to share that, you can remove the battery if the notebook will be stored (turned off and not plugged into AC power) for more than 2 weeks and also you have to remove the battery if the notebook will be plugged into AC power continuously (via a wall adapter or docking station).

     

    Additionally, for more information to preserve the life of your battery, make certain to charge the battery regularly. In cases of long-term storage, the battery must be charged at 20 to 50 percent to save capacity loss by self-discharge, and to avoid deterioration of battery performance.

     

    In a discharged condition, the battery voltage decreases faster. Storage in a 100 percent charged condition can cause higher self-discharge and deterioration of discharge capacity even after recharging, compared to storage in a 20 to 50 percent charged condition.

     

    Additionally, I would like to provide some more information regarding increasing the battery performance.

     

    A.  Do not leave batteries unused for long periods. If using more than one, rotate them.

    B.  If normally using AC power, make a practice of using the battery as the power source at least once a week.

    C.  Unplug the AC adapter when the notebook is not in use.

    D.  To preserve the life of a battery, be sure to charge it regularly.

    E.  Avoid using or charging batteries at high temperatures.

     

    Please refer the below web site for the Battery care practices:
