11.2.3 Battery
The car is equipped with 14 Ah AGM battery.
The battery is a crucial component interacting with engine and gearbox management systems. Pay particular
attention to its charge level especially if you are running reset procedures.
It is particularly important to keep the SOC (state of charge) of the battery at an high rate, running with the
battery at low SOC may reduce its performance and affect the battery SOH (state of health).
NOTE: brand new batteries should undergo a full charging cycle (with specific charger) before the first use.
NOTE: to extend the battery life and prevent noisy battery voltages it is recommended to keep the SOC and
SOH of the battery under control and include the battery charging in the standard routines of maintenance
of the car.
NOTE: the jump battery connector is not directly connected to the battery, it is isolated by the master
switch. If the battery charger is plugged to the jump battery connector it will not charge the battery (if main
switch is OFF). It is recommended to use a separarte harness for the in-car charging.
NOTE: running engine at low revs will not charge battery!
NOTE: if the battery power is low high current consumptions (like a gearshift actuation/recharge) can result
in an engine stall, keeping higher revs and generator in charge will fix this occurrence.
11.2.4 Battery installation
It is recommended to apply a minimum of 5mm of padding, below and on the top of the battery case, and a
2mm padding per side in order to protect the battery from excessive vibration.
The padding also protects the battery casing from getting damaged. It is recommended using closed cell
neoprene.
It is also important that when strapping the battery in place, the padding is not excessively compressed, as
this would minimize its effect.
It is also recommended that the battery cables are fully supported so they do not add any extra stress onto
the battery terminals. If they are too short, the engines vibrations when revved will be transferred through
the cable to the battery. If the cables are too long, they may weight enough to move when accelerating,
braking or cornering, adding extra stress to the battery terminals.
A battery, which has been damaged due to vibration, will show a good open circuit voltage (12.8v or more),
but when loaded, the voltage drops to zero. The battery casing usually also shows signs of wear on the casing.
It is also important that when attaching cables to the battery terminals, that the retaining nut is tightened to
4Nm and no higher.
