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 battery is rated 5200 mAh - 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. This battery is still compatible if your original battery has a lower power rating. It just means this one will last even longer!
You can expect about 2 hours to 3 hours of run time with this computer battery when new, 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). The higher capacity battery cells inside this cartridge have an energy capacity of 5200 mAh. This battery will be compatible with batteries rated at 4400 & 4800 mAh capacities while providing up to 20% more run time.
