    Hello,

    Recently I bought an Aspire 9303 with 4000mAh battery at 11.1 Volt (3UR18650Y-2-QC236). The laptop is excellent, but the battery’s life is only 1.5 to 2 hours. Is there a highest capacity battery for the Aspire 9303?
    The local Acer customer support said to me that I can use a bigger battery with 4800mAh at 14.8 Volt. :eek:
    How much dangerous it is the use of 14.8 Volt instead of 11.1 Volt?

    Thank you very much

    It wouldn't be dangerous to use a higher voltage if it's a retail battery made by Acer. HOWEVER, if you use a generic battery [like many on ebay], use caution.

    4000mAh to 4800mAh is not a big increase in battery life

    I would guess it extending your life about 20%(4800/4000) x 100

    see if you can get a 7800mAh, I have this one and I can get over 3 hours, with processors running at 2.0ghz...
