2.1.1 Batteries
CAUTION ! The Super Maramu 2000 is equipped with
high load lead-acid batteries.
These lead-acid batteries produce hydrogen gas which
is easily flammable. If ignited from a spark or a flame,
this gas can cause a violent explosion, involve acid
spreads, damage the battery and might cause bodily
damages.
Don't smoke around the batteries. Wear safety goggles
and insulated gloves while working nearby the batteries.
If battery acid comes into contact with unprotected skin,
wash off immediately, using plenty of water and soap. If
battery acid comes into contact with the eyes, flush
immediately with plenty of water and get medical
assistance without delay.
These batteries are located into a watertight and
gastight locked down containment. Once it is unlocked,
make sure children cannot get access inside.
The containment is fitted with a vent hose which drains
the gas outside of the boat.
a) Operation
The batteries are located in a watertight and gastight compartment, under the berth in the
passageway.
There are 9 batteries, 12 V and 105 Ah each. However, they are connected in two separate
circuits as follows :
12 V circuit: One only battery feeds the starters of both main engine and power generator
engine. It is situated towards the front of the boat.
It is charged from two 12 V alternators one on each of these engines.
24 V circuit: Eight batteries connected in series two by two and then in parallel, make a 24
V battery group of 400 Ah which feeds all the 24 V equipment on the boat (lights, winches,
sail furlers, fridges, electronics, pumps …).
They are charged by battery chargers 220 / 24 V or the main engine alternator.
Two main circuit breakers (outside the battery container in the passageway) switch on or off
both circuits. The top one switches the positives (both 12 and 24 V). The bottom one
switches the negatives (both 12 and 24 V).
