* Back current drain is the amount of current drawn by the charger from the battery, when the charger is connected to the battery, without power cord connected. The Benton has extremely low back current drain which corresponds to 0.7 Ah per month ( 1mA/hr)

** Ripple refers to interference of current and voltage. A high current ripple heats up the battery and reduces the life of the battery. Against a linear charger, which has a current ripple of up to 400%, the Benton charger’s current ripple is below 2% (0.15/12V battery voltage), which is much lower that the maximum 5% for a sealed acid battery. Equipment thus connected to the battery could not be damaged by high voltage ripples.
