– 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 recharging
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, measure
the voltage between the terminals. The amount given
(open circuit voltage) gives an indication of the opera-
tions to be carried out, as per the following table:
Check the battery voltage at least 12-24 hours after
recharging.

A) General information
In a sealed “dual” battery, the electrolyte for each ele-
ment 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 mo ved.
B) Recommendations for correct use
To keep the battery performing at optimum levels
and to increase its life, various precautions should be
taken:
– always keep the battery fully charged;
– always recharge a flat battery within 1 month, other-
wise the elements could be damaged and no longer
able to take the charge (sulphated);
– always recharge the battery before and after periods
of prolonged inactivity or storage.
WARNING!
Recharge only with the charger with constant voltage.
Using other types of battery charger could damage
the battery.
C) Rules for recharging the battery
Recharging is a particularly important operation for the
life of the battery and must be carried out according to
these 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 the appropriate battery charger;
