9 Cell Battery Dell Inspiron 1440 1440n 1750 1750n K450N

This brand new Dell Inspiron replacement laptop battery features lithium-ion cells. This battery is going to be physically larger than the original and will cause the rear of the laptop to tilt up slightly allowing for more air to flow underneath the computer. Li-ion battery technology provides longer run times with less weight. In addition, Li-ion batteries are not subject to the memory effect common with older battery technology. This Xtend brand laptop battery replacement is 100% compatible with the original battery specifications and is individually tested and backed by a 2 Year warranty.
