The battery charging unit located on the forward
bilge bulkhead 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 and increase.
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.
