Battery maintenance
The battery is an electrical device which requires careful monitoring and diligent maintenance. The
maintenance rules are:
1) Check the level of the electrolyte
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's electrical
system: the battery works overcharged and is subject to quick wear.
2)Load status check
After restoring the electrolyte level, check its density using an appropriate densitometer (see the figure).
When the battery is charged, you should detect a density of 30 to 32 Bé corresponding to a specific
weight of 1.26 to 1.28 at a temperature of no lower than 15° C.
A density reading of less than 20° Bé indicates that the battery is completely flat and it must therefore
be recharged.
If the scooter is not used for a given time (1 month or more) it will be necessary to periodically recharge
the battery.
The battery runs down completely in the course of three months. If it is necessary to refit the battery in
the vehicle, be careful not to reverse the connections, remembering that the ground wire (black) marked
(-) must be connected to the -negative clamp while the other two red wires marked (+) must be con-
nected to the clamp marked with the +positive sign.
3) Recharging the battery
Remove the battery from the vehicle removing the negative clamp first.
The normal bench charging must be carried out with the specific (single or multiple) battery charger,
placing the battery charger selector on the type of battery to be recharged. The connections to the power
supply must be made by connecting to the corresponding poles (+ with+ and -with -).
4) Battery cleaning
The battery should always be kept clean, especially on its top side, and the terminals should be coated
with Vaseline.
WARNING
BEFORE RECHARGING THE BATTERY, REMOVE THE PLUGS OF EACH CELL. KEEP SPARKS
AND NAKED FLAMES AWAY FROM THE BATTERY WHILE RECHARGING.
