battery and the battery voltage
increases steadily to maximum
voltage. At this point the voltage will
be regulated and held at a constant
level by the charging current, then
dropping gradually. When the
charging current has dropped below
0.4A, the charger switches to
maintenance charging.
If the battery is loaded and the
battery voltage drops to 12.9V, the
charger automatically reverts to the
start of the charging cycle.
Charging steps:
1) Desulphation: Desulphation
with pulses for sulphated batteries.
2) Bulk: Main charging where
around 80% of the charge takes
place. The charge is carried out at
constant charge until full voltage
has reached the set level.
3) Absorption: Final part of the
charge up to almost 100%. The
terminal voltage is kept constant at
a set level. During this step the
charge current falls gradually to
ensure the terminal voltage does
not get too high. If the absorption
phase has been in progress for
more than 12 hours, the charger will
switch to maintenance charging.
This feature protects against
damage if a problem is detected in
the battery.
4) Pulse: Maintenance charging.
The state of charge is between 95%
and 100%. The battery receives a
pulse when the voltage drops.
This keeps the battery in trim when
not in use. The charger could be
connected for months at a time.
Check the water level in the battery
if possible.
