At this point I''m thinking that the problem lie in how the laptop uses the battery though I''m not sure how to test this. Once the power cable is unplugged, the laptop will remain on but the built in battery light turns orange. It abruptly shuts down after about 10 minutes so it is using the battery to an extent. This is a Dell Inspiron 6400.

A 4.00V-4.09V means the battery is slightly undercharged. A 4.10V–4.15V is a complete charge, and when it reaches a 4.16V–4.20V reading, the voltage is higher than the original input. The battery voltage depends on when the charger decides to cut off power. The lower the cut-off current, the higher the voltage.
