7.8 CARE AND MAINTENANCE OF THE SEALED BATTERY
A) General information
In a sealed “dual” battery, the electrolyte for each element 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, otherwise 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.
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;
– 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 im-
mediately 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 operations
to be carried out, as per the following table:
Check the battery voltage at least 12-24 hours after recharging.
