Gilera Stalker 50, Service Manual

Page: 54 / 164

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.
