*) Back current drain is the current that the charger drains from the battery if the AC cord is disconnected.
**) 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 produces very high quality voltage and current with low ripple.
***) IP44 cannot be guaranteed if the charger is not positioned horizontally with the long side or top side turned up.
