   By zain ahmed (india) on January 30, 2013
   
   i am using a qosmio 770 will this 12 cell one work on my laptop??
   
   eBuyBatteries Response: It should be Toshiba Qosmio X770, right? The Qosmio X770 uses Toshiba PA3928U-1BRS battery, not this one.

   By jonesy82 (Kabul, Afghanistan) on October 28, 2012
   
   Very Glad I've upgraded to a 12-cell battery. It has pushed my battery time to over 6hrs of laptop use if I'm using power saving settings. This is a great importance while working overseas where power outages are frequent.

10. Toshiba 12 cells battery
    By Jay Marshall (Newark, NJ) on April 10, 2012
    
    The battery is good, it raises the back side of laptop up off the desk, now the laptop has a better airflow. Of course, it lasts much longer due to more cells.
