This is a brand new Dell Studio XPS premium grade replacement battery. This battery is going to be physically larger than the original and will cause the back of the laptop to tilt up slightly as the battery is thicker and it will protrude under the laptop about an inch. 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.

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 Dell Studio XPS notebook. The battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.

You can expect about 3 - 5 hours of run time with this XPS 16 battery when new, depending on your energy use.
