density is about 1.27, corresponding to
31º Bé, and these values are stabi-
lised.
•
Once the charge is over, level the acid
(by adding distilled water). Close and
clean carefully.
•
Once the above operations have been
performed, install the battery on the ve-
hicle making sure that it is properly
wired up.
1 Hold the tube upright
2 Carry out a visual inspection
3 The float must be released
Electrolyte level check
The electrolyte level must be checked frequently and must reach the upper level. Only use distilled
water to restore this level. If it is necessary to add water too frequently, check the vehicle electrical
system: the battery works overcharged and is subject to quick wear.
Charge status check
After topping-up the electrolyte level, check its density using the appropriate densitometer.
With the battery charged, a density of 30÷32 Bé, corresponding to a specific weight of 1.26÷1.28, must
be at a minimum temperature of 15° C.
A density reading below 20° Bé indicates that the battery is completely flat and must therefore be
recharged.
If the vehicle is not used for a certain time (1 month or more), the battery needs to be recharged peri-
odically.
The battery runs down completely in about three months. Should the battery be refitted on the vehicle,
be careful not to invert its connections, keeping in mind that the ( black ) earth wire marked (-) is con-
nected to the - negative terminal whereas the other two red wires marked (+) are connected to the +
positive terminal.
Battery recharge
WARNING
BEFORE RECHARGING THE BATTERY, REMOVE THE PLUGS OF EACH CELL. KEEP OPEN
FLAMES OR SPARKS AWAY FROM THE BATTERY WHILE CHARGING.
First detach the negative terminal before removing the battery from the vehicle.
Normal bench charging must be performed using the special battery charger, setting the battery charge
selector to the type of battery to be recharged (therefore, at a current equivalent to 1/10 of the battery
