This is a brand new Dell Studio premium grade replacement battery. This 9-cell battery is physically larger than the original and will stick out of the bottom of the laptop about an inch. It will still snap in and power the computer but will cause the back to stick up. This will make the keyboard face you more allowing for easier typing and increased airflow underneath the laptop keeping it cooler. 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 Dell Studio 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 3 - 5 hours of run time with this computer battery when new, depending on your energy use.
This battery replaces the Dell Studio 1450, 1450n, 1457, 1457n, 1458, 1458n series laptops.
