    is it safe to use a laptop w/o battery? i'll just connect it to the power outlet?

    the laptop is just being used here at home, and hardly taken out.

    yeah as per vendors advice it is definitely useful to use your laptop w/o battery... this is because if you use the laptop with battery it will automatically charge it, once such is fully charge you cannot pull it out from the laptop while it is running and eventually your battery will be over charged. so better use your laptop without battery to prolong your batteries life. it is useful for emergency purposes only so better take care of your OEM battery. hehehehe

    JUST make sure that the power cord is plugged in to a UPS so you can still power down your laptop safely if a power outage strikes.

    Commercial power is notorious for fluctuation and voltage sag that can surely damage your HDD.

    You can leave your charger and batteries connected indefinitely without damaging batteries because modern electronics have tickle/float-charge mechanism. Its a myth nowdays that batteries overcharge.

    Truth is, repeated discharge and charge cycle and reaching full discharge state wears battery faster, than leaving your batteries connected to AC.

    All laptops have circuitry built-in to prevent overcharging. It's actually the heat generated by the laptop that's responsible in reducing the life of the battery.

    If your laptop is used inside an airconditioned room or if you're using a proper laptop cooling pad, you can leave the battery inserted. This will help prevent data loss in case of a power failure.

    calibrate yung battery also from time to time, this is available on the bios option, to optimize battery performance in the long run.

    It is safe to use the laptop/notebook PC without the battery attached if you just always use it connected to the AC outlet.

    You can use a UPS to give your laptop the same power protection as having its battery still attached.

    A UPS is much cheaper (you can buy one just over P1k in price) than a replacement battery for your laptop. Typically a six-cell laptop battery would cost P5K and up.

    This statement might be true but I will not trust.
    The battery of my 6-mos old brand new acquired acer was damaged after 2-mos all time plugged on ac power with battery connected (was used for ******* files download/seed days and nites, 24/7). I learned my lesson so now I remove the battery if use at home using ac power connection. I use the battery twice a week just to fully discharge then recharge to keep it at top condition.
