Pulse - Maintenance charging.
Charging level varies between 95% and 100%. The
battery receives a pulse when the voltage drops. Keeps the battery in perfect condition
when it is not used. The charger can be connected for months at a time.

*) 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 800 is very low and cor-
responds to 1Ah per month.
**) 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 US 800 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.
