This is a new Dell W4FYY battery for the Dell Inspiron 14V, 14VR, N4020, N4030 and N4030D models. This W4FYY battery is rated 11.1 volts and 4400 mAh and will normally last 3 hours on a full charge.

We use the highest quality li-ion battery cells and components that charge faster, last longer and weigh less than cheaper, lower quality batteries. Low quality, cheaply made batteries can wear out in just a few months. These are the $10 batteries you'll find on Amazon and eBay. But you get what you pay for and you'll be ordering another battery in a few months.

This W4FYY battery is typically superior to the original battery and is 100% compatible with your Dell Inspiron 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 hours of run time with this Dell W4FYY battery when new, depending on your energy use. If you are looking for even longer battery run times, check out our DELL-103XT.
