The battery charging unit, located in the salon
behind the access door at the port end of the aft
sofa (Figure 6.22.1), is fully automatic and is
designed specifically for the marine environment.
The high frequency characteristic has allowed these
chargers to achieve a huge size and weight
reduction over their previously used equipment.
Commonly called high frequency or smart chargers,
these units bring a new sophistication to the battery
charger field. These units feature a built-in
amperage indicator located on the front panel. This
gives an accurate reading of the combined battery
current and load current. If the batteries are fully
charged and no load is present, the ammeter will
read near zero. To verify that the charger is
functioning properly, turn on lights or other load. The
ammeter should register an increase.
!
WARNING
Never block air circulation through the unit. Never
store any gear on top of the units.
NOTICE
Leave the converter running at all times to
maintain the 12 volt system voltage.
Charging characteristics contain three (3) elements:
•
Bulk Charge - this is initiated at power up and
provides the chargers full-rated current to the
battery bank until a predetermined voltage level
of 14.2V to 14.4V is achieved and/or a certain
time has passed.
•
Absorption Charge - this stage immediately
follows the bulk charge mode. It maintains the
battery voltage at the bulk charge voltage level,
but gradually decreases the current as the
battery accepts the charge until it reaches a
predetermined current level.

•
Float Charge - this stage is designed to hold
the battery at a safe, low voltage (typically
13.3V) providing up to the chargers full rated
amperage to accommodate DC load
requirements. The charge will remain in this
mode until the AC power is cycled off and then
on again.
