Get longer battery life and improved laptop performance with a new Dell Latitude KM742 replacement battery. There are two key components inside your battery pack to look for when buying a new computer battery. The quality of the batterys 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 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. Simply put, more is better. And yes, this battery is probably better than your original!
The other key component inside the battery pack is the computer chip set that contains the program interface with your laptops battery meter software and important safety features that monitors when to charge and stop charging your battery. We use Texas Instruments top notch components for this.
