INSTRUCTIONS FOR REFRESHING THE STOCK CHARGE OF AN OPEN CIRCUIT
1) Voltage check
Before installing the battery on the vehicle, check the open circuit voltage with a normal tester.
- If the voltage exceeds 12.60 V, the battery may 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 equal to 14.40÷14.70V
-Initial charge voltage equal to 0.3÷0.5 for nominal capacity
-Duration of the charge: 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
-Duration of the charge: 5 h
WARNING
-WHEN THE BATTERY IS REALLY FLAT (WELL BELOW 12.6V) IT MIGHT BE THAT 5 HOURS OF
RECHARGING ARE NOT ENOUGH TO ACHIEVE OPTIMAL PERFORMANCE.
IN THESE CONDITIONS IT IS HOWEVER ESSENTIAL NOT TO EXCEED EIGHT HOURS OF CON-
TINUOUS RECHARGING SO AS NOT TO DAMAGE THE BATTERY ITSELF.
