We use the highest quality lithium-ion cells that charge faster and last longer. We're so confident in the quality of our laptop batteries that each one is backed by a 2 year warranty and 30 day guarantee.

There are two key components inside your battery pack to look for when buying a new computer battery. The quality of the battery’s lithium-ion cells and the quality of the computer chip set in the battery pack. This battery is built with the best components, not the cheapest.

This 0X409G battery is rated at 5200 mAh or 58 Whr. This is the highest rating available for a 6 cell battery pack. The higher the mAh rating, the longer your battery will run before it needs to be recharged again. There are no compatibility issues if your existing battery is rated at 4400 or 4800 mAh or a lower Whr.

You can expect about 2 hours to 3 hours of run time with this battery, depending on your energy use. If you are looking for even longer battery run times, check out our extended run battery for your Dell laptop (our DELL-83XT).
