If your laptop has been running slowly or doesn’t last long without a charger, you need a new battery. And when looking for a replacement battery, quality is key. That’s why we use only the highest quality lithium-ion battery cells from Samsung. Higher quality cells charge faster and last longer. Laptop batteries also use computer chips to communicate with the laptop’s power and safety software. We use the highest quality chips from Texas Instruments. Every battery is individually tested and comes with a 2 year warranty.

This Dell XPS 14 (L401X), XPS 15 (L501X), and XPS 17 (L701X, L702X) is rated 7,800 mAh, one of the highest capacity li-ion batteries on the market. The higher the mAh (milli-amp hour) the longer your battery will last without a charge. This higher capacity battery will still be compatible if your original battery has a lower mAh or lower voltage rating. It just means it will last longer than the original.

You can expect about 3-6 hours of run time with this computer battery when new, depending on your energy use. The higher capacity battery cells inside this cartridge have an energy capacity of 6600 mAh. This battery will be compatible with all 6 cell batteries or other 9 cell batteries rated at 4400 & 4800 mAh.
