There is only one operational battery, the "external". The internal battery is a small button cell that is used to power the NVRAM, and does not power the laptop.
I'm not talking about the button cell. My E6400 has a "6-Cell Lithium-Ion Primary Battery for Dell Latitude". In addition, I purchased the 84 WHr Extended Battery Slice for Dell Latitude E6400/6400.
The 6 cell fits inside the laptop case, the slice attaches to the bottom of the laptop. Since the 6 cell can be charged while docked, I'd like for that battery to deplete before the slice. Unfortunately, it works the other way.
