Get longer battery life and improved laptop performance with a new Dell Latitude E6510 battery. Our batteries use the highest quality lithium-ion cells that charge faster and last longer.

This Dell E6510 battery uses the highest-quality lithium-ion battery cells and components that charge faster and last longer than cheaper, lower quality battery cells.

This battery is rated 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. It just means this one will last longer than the original battery!

When choosing a laptop battery, cheaper is not better. Cheaper batteries use inferior Chinese cells that typically wear out in just 3 to 6 months. The main indicators of inferior Chinese cells are the low price of the battery and a lower mAh rating. Inferior batteries also use inferior computer chip sets inside that can lead to compatibility issues with your laptop. Although every brand of laptop battery is hand assembled in China, the key to getting a great battery is knowing what components are inside.
