A replacement battery for Toshiba PA3287U cells are a hot commodity as these batteries are used on a large number of Toshiba laptops including the Satellite 2450 series, Satellite A20 and A25 models and Toshiba Satellite A40 and A45 laptops. Installing new replacement batteries from USB Phone World is a good economic strategy as our batteries are price well-below retail. Our 3287 battery is 100 percent OEM compatible and is guaranteed to work flawlessly on your Toshiba laptop. If you are replacing the original 6-cell Toshiba battery with our battery, you will notice improved performance over the original battery. You can expect to see longer charge times with our batteries and recharging should be a slightly faster process. The improved performance is a result of our batteries being manufactured with the latest lithium technology. In addition to 6-cell batteries, Toshiba laptops that use PA3287U batteries can support 12-cell batteries. USB Phone World also has 12-cell batteries available for Toshiba laptop owners who want to boost the charge capacity available for their computers. These batteries are a little heavier than their 6-cell counterparts but Toshiba laptops with 12-cell batteries can see a doubling of charge times allowing for many more hours of computing before an AC adapter is required.
