This is a brand new Dell premium grade replacement battery. 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.
This battery replaces the original battery found in Dell Precision Mobile M4600, M4700, M4800, M6600, M6700 and M6800 WorkStation series laptops.
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 Dell Precision M4600 battery is typically superior to the original battery and is 100% compatible with your Dell Precision computer. The battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.
