*) The quality of the charging voltage and charging current are very important. High current
ripple heats the battery and ages the positive electrode. High voltage ripple can damage
other equipment connected to batteries. The battery chargers from CTEK produce very high-
quality voltage and current with low ripple
**) MPPT (Maximum Power Point Tracking) finds the best combination of supply current and
voltage to maximize the power output. This is especially important for Photovoltaic (Solar)
Panels and trailer campers with wiring constraints.
