In any case, when increasing battery capacity, it is advisable not to exceed 20-30% of the maximum values provided as optional by
IVECO, so as not to damage some of the components (e.g. starter motor). When higher capacities are necessary, use additional
batteries, making the necessary provisions for recharging as indicated below.
Additional batteries
The addition of a battery in the vehicle electrical system requires the provision of a circuit that, during start-up, makes it possible to
section this battery with respect to the original. Given the new "smart" recharge strategies, the auxiliary battery must be equivalent
to the originally installed battery and must have the same capacity (110 Ah).
In cases where it is necessary to use an additional battery in parallel with the series, we recommend the use of a larger alternator or
the installation of an extra alternator.
The batteries can be traditional or "recombination" (AGM or gel).
Due to the normal chemical reaction that generates acid vapours during charging, installation must be performed in a way that
ensures the safety of people and the protection of the vehicle.
Therefore, regardless of the type of battery, if you do not already have a segregated compartment, it is necessary to:
a) provide an airtight container corresponding to the passenger compartment, equipped with a system that vents vapours to the
outside of the vehicle,
or
b) use a battery equipped with a lid with a vapour extraction system, anti-backfire (flame arrestor) system and a vent tube to the
outside of the housing.
Also bear in mind that:
● vent systems should not cause depression inside the battery;
● the vapour release point must not be in areas where sparks can be triggered or near hear sources;
● the maximum allowable temperatures, for a short period of time, are 50°C for conventional batteries and 40°C for AGM or
gel batteries.
▶ Ground connection of the additional battery must be made using a cable (the shortest possible)
of adequate section.
