Title: Not for a Latitude C640 as listed
Review: As another reviewer indicated, this isn't the same type of battery that comes in the Dell Latitude C640 (my computer). This is a straight line of 6 cells, where the Dell battery is two rows of 3 cells. As a result, I was unable to use the battery. In trying to make it fit, I broke the battery, so I couldn't return it. My fault, so it's my loss. But I highly recommend you take a look at your current battery before ordering. There isn't much room inside a laptop. The same other reviewer said he got it to work, but I don't know how.
