7.5 Hermetic battery care and maintenance

A) General information
In recombination hermetic batteries, the electrolyte of each element is accurately dosed
in the production stage and sealed at source in order to guarantee maximum efficiency
throughout the battery's life cycle.
Warning! There is no need to add water or acid to this type of battery and it
must never be opened nor the cover removed.
B) Recommendations for correct use
To maintain battery efficiency and increase it's duration, certain precautions should be taken:
• Always keep the battery in a good state of charge.
• Always fully charge a flat battery within 1 month, otherwise it may get damaged and no
longer be rechargeable (sulfation).
• Always charge the battery before and after a prolonged period of inactivity or storage.
Charge using a constant voltage battery charger only. The use of any other
type of battery charger could damage the battery.
C) Rules for battery charging
The charging operation is particularly important for the duration of the battery and must be
carried out in accordance with these prescriptions:
• Do not charge batteries if the casing is broken or cracked;
• Carefully read the user instructions provided with the battery charger and battery;
• Use a suitable battery charger;
• Charge in an environment with an ambient temperature of between +10°C and +30°C.
Warning! When charging, make sure that the battery does not heat up to over
50°C; if this happens stop charging immediately and replace the battery as it
is unusable.
With the battery disconnected (and unused for at least 12 hours) and the tester in voltmeter
mode, measure the voltage between the poles; the value detected (open circuit voltage) pro-
vides an indication of the operations to be carried out as indicated in the table below:
Open circuit battery voltage
13.1 Volt
12.6 Volt
< 12.4 Volt
Note! Check the battery voltage after at least 12-24 hours following charging.
