4.3 Charge algorithm
4.3.1. Overview
Several preset charge curves and one user adjustable curve are available, see table
below.
The DEFAULT-setting is algorithm nr 2.
Make sure the charge algorithm is correct for the battery-type that must be
charged. If necessary, contact the battery supplier for the appropriate
battery-settings. Wrong battery settings can cause serious damage to the
batteries.
