BATTERY (TE-SMR-TXC)
The sealed battery (1) does not require any maintenance work. If the vehicle
remains unused for long periods, it is recommended to remove battery from
electrical system and store it in a dry place. After an intensive use of the battery,
it’s advisable a standard low charge (12V-6Ah battery: 0.6A for 8 hours; 12V-
7Ah battery: 0.7A for 8 hours). Rapid recharging is advised only in situations of
extreme necessity since the life of lead elements is reduced (6A for 0.5 hours
with 12V-6Ah batteries;
7A for 0.5 hours with 12V-7Ah batteries
).
Battery recharge
To gain access to the battery (1):
- remove the saddle (see page E.15);
- 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 not, the battery needs to be charged. Using a battery charter
with a constant voltage, first connect the RED positive cable to the battery’s positive terminal then the BLACK negative cable to the
battery’s negative terminal. Apply to the constant voltage of 14,4 V a current of “x” Ampere as results in the belowe diagram (depend-
ing on the amount of carging required). 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 charge level before reinstalling it on the
vehicle. The battery should be kept clean and the terminals coated with grease.
