*) Back Current Drain is what the charger uses to drain the battery if the power cord is
disconnected. The reverse current of the MULTI US 25000 is very low.
**) The ripple wave describes how many disturbances are exhibited by current and volt-
age. A rippled voltage can cause damage to other equipment connected to the battery.
The MULTI US 25000 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.
