We use the highest quality lithium-ion battery cells that charge faster and last longer. Quality cells can make the difference between a 6 month lifespan or a 4 year lifespan. We're so confident in our laptop battery quality that we back each one with a 2 year warranty and 30 day return.
This battery is rated 5200 mAh - the highest rating on the market for a 6 cell battery pack. The higher the mAh rating, the longer your battery will run before it needs to be charged again. This battery is still compatible even if your existing battery has a lower mAh rating. It just means this one will last longer than the original!
