• the battery cables from the terminals Fig. B
IMPORTANT NOTICE
Disconnect the negative cable of the battery “A” fi rst, and
then the positive cable “B” Fig. B.
Detach:
• The battery
• Remove the battery rubber tip and slide out the battery “D”.
Check:
• The battery charge level
Connect a pocket tester to the battery terminals Fig. C.
Check the battery level as shown in the tables of the following
example Fig. D.
NOTE:__________________________________________
The charge status of a battery can be checked by measuring
its open-circuit voltage (that is the voltage when the positive
terminal is disconnected).
If the open-circuit voltage is equal to/above 12.8 V, recharg-
ing is not necessary.
EXAMPLE:
- Open-circuit voltage = 12.0 V
- Charging time = 6.5 hours
- Battery charge amount = 20 -30%
-
Recharge:
• The battery (see the fi gure with the suitable charging man-
ner)
IMPORTANT NOTICE
Do not carry out a quick charging of the battery.
WARNING
• Never remove the caps that seal the battery.
• Do not use fast battery charger as these devices transfer
a high-amperage current to the battery at high speed,
therefore the battery may overheat and its parts may be
damaged.
If it is not possible to adjust the charging current of the bat-
tery charger, be careful to prevent the battery overcharge.
For charging, disconnect the battery from the vehicle.
(Should it be necessary to recharge with the battery mount-
ed on the vehicle, disconnect the negative cable from the
battery terminal).
To reduce the risk of sparks, connect the battery charger to
the power supply only after having connected the cables to
the battery.
