*) The back current drain is the current that the charger uses from the battery when
the wall plug is not connected. The reverse current of the US 3300 Corvette (model
1051) is very low and corresponds to 1 Ah per month.
**)The ripple wave describes how many disturbances are exhibited by current and
voltage. A rippled voltage can cause damage to other equipment connected to the
battery. The US 3300 Corvette (model 1051) supplies voltage and current with very
low voltage rippling. This increases the life of the battery and ensures that equipment
connected to it will not be damaged.
