Besides, upon pre-delivery it is therefore necessary to check the battery charge and recharge it, if
required, before storing the vehicle and, afterwards, every six months.
INSTRUCTIONS FOR THE BATTERY REFRESH AFTER OPEN-CIRCUIT STORAGE
1) Voltage check
Before installing the battery on the vehicle, check the open circuit voltage with a regular tester.
- If voltage exceeds 12.60 V, the battery can be installed without any renewal recharge.
- If voltage is below 12.60 V, a renewal recharge is required as explained in 2).
2) Constant voltage battery charge mode
- Constant voltage charge equal to 14.40 ÷ 14.70V
- Initial charge voltage equal to 0.3 ÷ 0.5 for Nominal capacity
- Charge time:
10 to 12 h recommended
Minimum 6 h
Maximum 24 h
3) Constant current battery charge mode
- Charge current equal to 1/10 of the nominal capacity of the battery
- Charge time: 5 h
CAUTION
NEVER USE FUSES WITH A CAPACITY HIGHER THAN THE RECOMMENDED CAPACITY. USING
A FUSE OF UNSUITABLE RATING MAY SERIOUSLY DAMAGE THE VEHICLE OR EVEN CAUSE
A FIRE.
CHARGE THE BATTERY BEFORE USE TO ENSURE OPTIMUM PERFORMANCE. INADEQUATE
CHARGING OF THE BATTERY WITH A LOW ELECTROLYTE LEVEL BEFORE IT IS FIRST USED
SHORTENS THE LIFE OF THE BATTERY.
IF THE VEHICLE IS NOT USED FOR SOME TIME (1 MONTH OR MORE) THE BATTERY NEEDS
TO BE RECHARGED PERIODICALLY. THE BATTERY RUNS DOWN COMPLETELY IN THE
COURSE OF THREE MONTHS. IF IT IS NECESSARY TO REFIT THE BATTERY IN THE VEHICLE,
BE CAREFUL NOT TO REVERSE THE CONNECTIONS TAKING INTO ACCOUNT THAT THE
GROUND WIRE (BLACK) MARKED(-) MUST BE CONNECTED TO THE - NEGATIVE TERMINAL
WHILE THE OTHER TWO RED WIRES MARKED (+) MUST BE CONNECTED TO THE TERMINAL
MARKED WITH THE +POSITIVE SIGN
WARNING
WHEN THE BATTERY IS REALLY FLAT (WELL BELOW 12.6V) IT MIGHT OCCUR THAT 5 HOURS
OF RECHARGING ARE NOT ENOUGH TO ACHIEVE OPTIMAL PERFORMANCE.
GIVEN THESE CONDITIONS IT IS HOWEVER ESSENTIAL NOT TO EXCEED 8 HOURS OF CON-
TINUOUS RECHARGING SO AS NOT TO DAMAGE THE BATTERY ITSELF.
Dry-charge battery
- Remove the battery ventilation duct closing cap and remove the caps from the single elements.
- Fill the battery with electrolyte having a density of 1.270+/-0.01 Kg/l (corresponding to 31+/-1 Bé) with
minimum ambient temperature of 15 °C, up to the top level indicated on the single block.
- Slightly tilt the battery to remove any air bubbles formed during the filling.
- Place the caps on the filling holes of the single elements without tightening them and let the battery
stand. During this phase, the battery undergoes a gasification phenomenon and temperature rises.
