What Causes the Conditioning Message on the Monitor?

In addition to the value for the full capacity, the battery also stores a value for the Max Error. The Max
Error tracks the maximum possible deviation of the estimated charge of a battery from the actual
charge.
If a battery is charged or discharged partially, or if it is charged while the monitor is being used, the
accuracy of the "reference points" for the fully discharged and fully charged states decreases, causing
an increase in the value for the Max Error (see diagram, below).
When the Max Error rises over a certain limit, a message is displayed prompting the user to condition
the battery, as described in "Conditioning Batteries" on page 104.
You can reset the value for the Max Error before the battery needs conditioning, by performing the
steps described in "Conditioning Batteries" on page 104. The minimum value of the Max Error after
conditioning is 2%.
