I just recently purchased a new Dell Inspiron 8600 laptop. I called Dell about the batteries..AKA do you need to break them in?. They are L Ion batteries. The tech said that you need to run the batteries down for a month of use, and keep recharging them when they are low. He said that that would increase the lifespan of of the batteries. So my Q is this, was I given a crock of BS or do I need to break the batteries in?
