Aging Factor
The bq2084-V150 adds a new aging factor called DF: Age Factor which scales cell impedances as the cycle
count increases. This new factor is used to accommodate for much higher impedances observed in larger
capacity and/or aged cells. For most applications the default value of zero is sufficient. However, for some very
