6.0 Charging Times
The time taken for the Truecharge to fully recharge the battery(s) connected to it
depends on many factors such as, the size (capacity in amp hours) of the battery (or
total capacity if two batteries are connected), and how deeply the battery(s) are
discharged. The following simple formula can be used to establish the approximate
expected charging time.

Where "Depth of Discharge" is the percentage of charge that has been used (0% is
fully charged, and 100% is completely discharged).
As an example, for a Group 27 size battery with a rated capacity of 80 amp hours
that is 75% discharged, the formula becomes:
