This is a brand new HP premium grade replacement battery. This battery has the same part number as the HP Business Notebook 510 and 530 but will not work with those models. Please make sure you have the correct model number before placing your order. 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. This laptop battery replacement is typically superior to the original battery and is 100% compatible with your HP notebook computer. The battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.

You can expect about 2 hours to 2-1/2 hours of run time with this computer battery when new, depending on your energy use.
