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 CONTINUOUS RECHARG-
ING SO AS NOT TO DAMAGE THE BATTERY ITSELF.

Dry-charge battery
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.
After charging the battery, check each element electrolyte level and density. 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 earth wire (
black
) marked (-) must be connected to the
- negative
terminal while the other two
red
wires marked (+) must be connected to the terminal marked with the +
positive
sign.
Regular bench charging must be carried out with the specific battery charger, (single) or (multiple),
setting the battery charger selector to the type of battery to be recharged. Connections to the power
supply source must be implemented by connecting the corresponding poles (+ to+ and - to -).
4) Cleaning the battery
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 the battery away from naked flames
or sparks when charging.
Remove the battery from the vehicle removing the negative clamp first.
