    Hi everyone,

    I bought the UL50AG for the long battery life as it is advertised at 12 hours. I'm getting around 6 hours with normal usage for a 15.6" laptop which is pretty good. The battery is an 8 cell with 4400mAh rating.

    Recently, I found one on eBay that has a 7800mAh rating that sticks out the back a little bit. I was wondering if anyone got a similar battery; and what their total usage time is?

    Edit: The link on ebay is:

    Thanks,
    Gnimble

    is there a replacement for the battery in the best buy ul80jt that will beef up its kinda dubious battery life? (gets like 3.5 to 4 hours with brightness dialed down and average usage.) i THINK it has a six-cell; i'd love to upgrade it to an 8-cell or so.

    I believe the battery linked above would fit your UL80. It sticks out the back a bit and also raised the laptop from the back. Classes start in a month for me so I'll evaluate the current battery after a few lecture sessions. If it is not enough, I might consider the extended battery.

    Cheers,

    @gnimble,
    12 hours is for standby...for normal usage, don't expect too much....it should only last about 5hrs max....
    :(

    12 hours is for light web browsing with wifi and bluetooth. You can get upwards with 16-18 hours for pure "standby" conditions.
