2. BATTERIES
This vehicle is provided with four (4) odyssey
group 31 absorbed glass mat (agm) 12-volt
batteries, model 31-pc2150s, connected in
series-parallel (Figure 15).
These batteries require no maintenance for their
lifetime. They can withstand deeper discharge
cycles and several times the charging cycles of
a standard battery.
These are sealed, valve regulated recombinant
batteries which means that the oxygen created
will recombine with the hydrogen in the battery,
creating water and preventing water loss. Water
never needs to be added to this type of battery.
The top-mounted negative and positive
terminals are tightly sealed to prevent leaks.
The electrolyte in this type of battery is absorbed
in micro-porous glass separators. This design
prevents spills and results in greater resistance
to vibration.
Always replace these batteries with identical
make and model batteries as the system is
balanced and optimized for this type of battery.
DANGER
Agm batteries generate hydrogen gas, which
is highly flammable. If ignited by a spark or
flame, the gas may explode violently, causing
spraying of acid, fragmentation of the battery,
which may result in severe personal injuries.
Wear safety glasses and do not smoke when
working near batteries. In case of contact with
acid, flush immediately with water.
WARNING
Battery posts, terminals and other related
accessories contain lead and lead
compounds, chemical known to the state of
california to cause cancer and other
reproductive harm.
Batteries also contain other chemicals known
to the state of california to cause cancer.
Wash hands after handling.
The battery has four (4) major functions:
1. Providing a source of current for starting the
engine;
2. Stabilizing the voltage in the electrical
system;
3. Supplying current for a limited time, when
electrical demands of the equipment exceed
the power output of the alternator;
4. Providing a limited source of power for
connected accessories, when the engine is
not running.
