BATTERY
The battery (1) is a sealed-for-life, maintenance-free battery. If the vehicle
remains unused for long periods, it is recommended to disconnect the battery
from the electrical system and store it in a dry place. After an intensive use of
the battery, it is advisable to carry out a standard slow charging cycle (12V-4Ah
battery: 0.6A for 8 hours).
Quick charging is advised only in situations of extreme necessity since the life
of lead elements is drastically reduced by such cycle (12V-4Ah battery: 6A for
0.5 hours).
Battery charger
To gain access to the battery (1):
- remove the saddle (as outlined in the relevant paragraph);
- first remove the BLACK negative cable, then the RED positive cable (when
reassembling, first connect the RED positive cable, then the BLACK negative
cable);
- remove the battery (1) from its housing.
Check, using a voltmeter, that battery voltage is not less than 12.5 V. If it is not
so, the battery needs to be charged. Using a battery charger with a constant
voltage, first connect the RED positive cable to the battery positive terminal
then the BLACK negative cable to the battery negative terminal. At a constant
voltage level of 14.4 V, apply “x” Amps according the battery's charge percent -
age as indicated in the table below. The voltage reaches a constant value only
after a few hours, therefore it is suggested NOT to measure it immediately after
having charged or discharged the battery. Always check the battery charge
before reinstalling it on the vehicle. The battery should be kept clean and the
terminals coated with grease.
