MAINTENANCE OF THE SEALED BATTERY
A) General information
In a sealed "dual" battery, the electrolyte for each el-
ement is carefully measured out during manufacture
and sea led at source, in order to ensure maximum
performance during the battery's entire life.
With a battery of this type, it is not necessary to add
water or acid, and the cover must never be opened or
re moved.
B) Recommendations for correct use
To keep the battery performing at optimum levels and
to increase its life, various precautions should be tak-
en:
– always keep the battery fully charged;
– always recharge a flat battery within 1 month, oth-
erwise the elements could be damaged and no
longer able to take the charge (sulphated);
– always recharge the battery before and after peri-
ods of prolonged inactivity or storage.
IMPORTANT! Only recharge with a constant voltage
battery charger. Use of other types of battery charger
could damage the battery.

C) Rules for recharging the battery
La ricarica è una operazione particolarmente IMPOR-
Recharging is a particularly important operation for
the life of the battery and must be carried out accord-
ing to the se instructions:
– do not recharge the battery when its case is broken
or damaged;
– carefully read the instructions for using the battery
charger and the battery;
– use a suitable battery charger;
– recharge at a room temperature of between +10
and +30 °C;
– check that the battery does not heat to beyond 50
°C while recharging. If it should do so, stop recharg-
ing immediately and dispose of the battery since it
will be unusable.
With the battery disconnected (and at rest for at least
12 hours) and the tester in voltmeter function, meas-
ure the voltage between the terminals. The amount
given (open circuit voltage) gives an indication of the
operations to be carried out, as per the following table:
Battery voltage
Battery state
with open circuit
> 12.6 Volt Fully charged
< 12,4 Volt Flat
Check the battery voltage at least 12-24 hours after
recharging.
