Longer running 12 Cell HP ProBook 4720s battery This is a brand new Extended Run HP ProBook premium grade replacement battery for the HP 17" screen 4720s. The main drain on a computer battery is the size and brightness of the display screen. Because of the large screen that comes with the 4720s, many people like the larger capacity battery featured here because it provides an additional 1 1/2 hours of run time of the standard size battery. This larger capacity battery pack will protrude to the bottom of your laptop about 1 inch. If you are using a docking station, the larger battery pack on the bottom of the laptop will prevent you from connecting to the docking station. Choose the 6 cell version of this battery instead. The superior South Korean cells inside the battery cartridge will provide longer run times between charges as well as a longer service life than cheaper batteries. In addition, Li-ion batteries are not subject to the memory effect common with older battery technology. This means you can recharge your laptop any time without diminishing your battery capacity.
