Dell Inspiron 640m Battery for Part Number UG679, RC107 and Y9943

This is a brand new Dell Inspiron 640m replacement battery. There are two things you need to look for when buying a new computer battery: the quality of the lithium-ion power cells inside the battery cartridge, and the quality of the computer chip in the battery pack. All of our batteries come with the highest quality components, not the cheapest. This battery contains the very best Li-ion cells on the market from Samsung.

The other key component inside the battery pack is the computer chip set that contains the program interface with your laptop’s battery meter software and important safety features that monitors when to charge and stop charging your battery. We make sure to only use Texas Instruments computer chips in all of our batteries.

When choosing a laptop battery, cheaper is not better. The cheap batteries you see online use inferior Chinese cells that typically wear out in just 3 to 6 months; The main indicators of inferior Chinese cells are the ridiculously low price, unsecure website, no phone number and the battery doesn’t ship from in the U.S. 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.

Laptop Battery Express is a US based business with knowledgeable support staff to assist you before and after the sale. YES, we have a phone number and real people answer your call! Free technical support is available if you need additional help in diagnosing power problems with your battery, ac power adapter or battery meter software.

All our products carry a full 2 Year warranty and every battery is charged and tested before it ships.

We provide a 30 day money back guarantee if you are not completely satisfied. We are so confident in the quality of our batteries, we will pay for any and all shipping expenses if our product fails to perform in the first 30 days you have our battery, even if it is not our fault. (PS- if your laptop will not turn on at all when plugged –in, you need a new ac power adapter found at the bottom of this page) Feel free to call for tech support.
