WARNING
-WHEN THE BATTERY IS REALLY FLAT (WELL BELOW 12.6V) IT MIGHT BE THAT 5 HOURS OF
RECHARGING ARE NOT ENOUGH TO ACHIEVE OPTIMAL PERFORMANCE.
IN THESE CONDITIONS IT IS HOWEVER ESSENTIAL NOT TO EXCEED EIGHT HOURS OF CON-
TINUOUS RECHARGING SO AS NOT TO DAMAGE THE BATTERY ITSELF.
Dry-charge battery
WARNING
THE BATTERY ELECTROLYTE IS POISONOUS AS IT MAY CAUSE SERIOUS BURNS. IT CON-
TAINS SULPHURIC ACID. AVOID CONTACT WITH THE EYES, THE SKIN AND CLOTHING. IF
COMING INTO CONTACT WITH EYES OR SKIN, WASH ABUNDANTLY WITH WATER FOR AP-

Battery
12V-9Ah
Commissioning dry-charge batteries:
1) Once the short closed tube and caps are removed, add sulphuric acid to the elements, of a type for
batteries with a specific gravity of 1.26, corresponding to 30° Bé at a temperature of at least 15°C until
reaching the upper level.
2) Let it sit for two hours.
3) Use the specific battery charger (single or multiple) to charge to an intensity equal to around 1/10 of
the capacity until the voltage has reached a value of around 2.7 V per element. The density of the acid
should be about 1.27, corresponding to 31° Bé, and the values have stabilised. The duration of the
charging operations must be 15 - 20 hours.
4) Once the charging is complete, level out the acid (add distilled water or remove excess acid), put
on the caps and clean carefully.
5) Once these operations have been completed, install the battery on the vehicle, correctly following
the connections described in point 3) « Battery charging ».
WARNING
- ONCE THE BATTERY HAS BEEN INSTALLED IN THE VEHICLE IT IS NECESSARY TO REPLACE
THE SHORT TUBE (WITH CLOSED END) NEAR THE + POSITIVE TERMINAL WITH THE CORRE-
SPONDING LONG TUBE (WITH OPEN END), THAT YOU FIND FITTED TO THE VEHICLE, TO
ENSURE THAT THE GASES THAT FORM CAN ESCAPE PROPERLY.
