When charging is completed, check the level and density of the electrolyte as well as the voltage of
each element. If the vehicle is not used for long periods of time (1 month or longer) the battery must be
periodically recharged.
The battery will completely discharge over three months. When the battery is refitted onto the vehicle,
be careful not to invert the connections: remember that the ground wire (black) needs to be connected
to the negative (-) terminal, while the red wire is connected to the terminal marked with the positive
(+) sign.
3) Recharging the battery
WARNING
BEFORE RECHARGING THE BATTERY, REMOVE THE CAPS OF EACH CELL.
KEEP THE BATTERY AWAY FROM NAKED FLAMES OR SPARKS WHILE IT IS CHARGED.
FIRST DETACH THE NEGATIVE LEAD BEFORE REMOVING THE BATTERY FROM THE VEHICLE.
Normal charging on the bench is done with the specific battery charger (single or multiple), positioning
the battery charger selector on the type of battery to recharge at a current of 0.9A for around 6 ÷ 8
hours. The connections with the power supply source must be made by connecting the corresponding
poles (+ with + and - with -). The battery caps must be removed during charging.

4) Cleaning the battery
The battery should always be kept clean, especially the upper part, and the terminals protected with
vaseline.
CAUTION
NEVER USE FUSES WITH A CAPACITY HIGHER THAN THE RECOMMENDED CAPACITY. USING
A FUSE OF UNSUITABLE RATING MAY SERIOUSLY DAMAGE THE VEHICLE OR EVEN CAUSE
A FIRE.
CAUTION
IN EMERGENCIES, THE CHARGING TIME CAN BE DECREASED TO 5-6 HOURS.
CAUTION
ORDINARY AND DRINKING WATER CONTAINS MINERAL SALTS THAT ARE HARMFUL FOR
THE BATTERY. FOR THIS REASON, YOU MUST ONLY USE DISTILLED WATER.
CAUTION
CHARGE THE BATTERY BEFORE USE TO ENSURE OPTIMUM PERFORMANCE. INADEQUATE
CHARGING OF THE BATTERY WITH A LOW LEVEL OF ELECTROLYTE BEFORE IT IS FIRST
USED SHORTENS THE LIFE OF THE BATTERY.
