*) 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 out-
put. This is especially important for Photovoltaic (Solar) Panels and trailer campers with wiring constraints.
