CTEK XS 800 - Manual (Page 5)

Charging phases:
Desulphation - Desulphation with pulsing for sulphated batteries.
Bulk - Main charge when 80% of charging takes place. The charger delivers a constant current
until the terminal voltage has risen to the set level.
Absorption - Complete charge up to virtually 100%. The terminal voltage is maintained at
the set level. During this phase the current drops successively so the terminal voltage does
not become too high. If the absorption phase has been in progress for more than 18 hours
the charger switches to maintenance charging. This function prevents damage if the battery
is faulty.
Pulse - Maintenance charging. Charging 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. If possible, check the water level in the battery.
TEMPERATURE PROTECTION
CTEK XS 800 is protected from being overheated. The power will be reduced if the ambient
temperature is raised.
MAINTENANCE
The charger is maintenance free. Note that disassembly of the charger is not permitted and
will void the warranty. If the power cord is damaged, the charger must be left to the reseller for
maintenance. The case can be cleaned with a soft damp cloth and mild cleanser. The charger
should be disconnected from the power while cleaning.
