To counteract the natural progressive - normally very slow - decay over time of the battery life, the user must keep
in mind that:
•
Extreme temperatures can affect battery capacity and charging efficiency.
•
Batteries must be stored at a temperature between 15 ° C and 36 ° C (the ideal temperature is around 20 ° C):
conditions other than those described above can affect the effectiveness of the recharge as well as the number
of possible recharges.
•
Leaving (and storing) the BATTERY in a hot (> 36 ° C) or cold (<15 ° C) environment reduces the battery capacity
and its life span.
•
If during the use of the Scooter you notice a significant drop in distributed power, immediately stop use and turn
it off using the switch.
The state of efficiency of the BATTERY, as regards the duration of delivery, must be periodically checked: batteries
that show a 20% reduction compared to the condition at the beginning of their life must be replaced and disposed of
in the manner provided (see Cap. "Disposal").
An indication of the current state of efficiency of the battery is the "burn-test" test (see User manual Burn - test).
Refer to the scooter user manual.

IDEAL CONDITIONS FOR BATTERY OPERATION AND DISCHARGE
It is recommended to use the BATTERY at a temperature between 15 ° C and 36 ° C.
To avoid rapid deterioration, the BATTERY must NEVER be completely discharged under any circumstances: the
cut-off device is present in to the BATTERY (see chapter "In the event of cut-off intervention").

CUT-OFF
NiMh BATTERY PACK integrates the following electronic devices / systems with the function of managing the safety
of the cells that make up the BATTERY.
Particular attention must be paid to the presence of the cut-off system as its intervention determines the supply of
energy to the Scooter and this occurs suddenly.
The non-operating condition imposed by the cut-off system is temporary and normal operation is restored after having
recharged the BATTERY using the special charger. The cut-of intervention is to be considered the electronic
BATTERY protection system against accidental total discharge, it is located inside the BATTERY and is connected
in series between the BATTERY and the Scooter motor.
The function is to prevent the excessive discharge of the cells with the possible danger of reversing the polarity of
one or more cells, with consequent possible destruction of the BATTERY pack with the potential to create even very
serious damage to things and / or people.
During the discharge of the batteries, the voltage drops until it reaches a limit value at which point the cut-off prevents,
by interrupting the power supply, the BATTERY can be discharged further.
When the cut-off intervenes, the battery no longer supplies voltage to the connector.
To restore the situation of use of the battery, it is necessary to recharge it only by means of the special battery charger
(see user manual of the battery charger) and restore the circuit.
The cut off intervention is to be considered exceptional and this event should not occur during normal use of the
battery, as the correct use of the vehicle does not require excessive discharge of the same.
•
Emergency thermostat: intervenes during the charging phase in the event of a BATTERY charger failure which
could lead to battery overcharging. It prevents the BATTERY from overheating by cutting off the charging current.
•
Cut - off: intervenes in case of attempt to overdischarge. It eliminates the electrical absorption by interrupting the
supply of current to the user device, it is restored by recharging the BATTERY.
•
Overcharge protection: during the charging phase it prevents the circumstance that the charger does not
automatically interrupt the charging period.
•
Short circuit protection: each cell inside the battery pack is individually protected electronically against accidental
short circuits, in any case DO NOT SHORT CIRCUIT THE BATTERY BECAUSE IT COULD DAMAGE THIS
SYSTEM IRREPARABLY and the BATTERY should be replaced.
12.1. IN THE EVENT OF CUT-OFF INTERVENTION
In case of intervention of the cut-off system, proceed as follows:
•
Follow the procedure for opening the scooter;
•
Disconnect the battery motor power connector;
IMPORTANT NOTE!
After using the Scooter, always cut off the power supply to the motor by using the
Scooter main switch: the electronic control of the Scooter motor board, even with
the engine not running, has a very low energy consumption which, in the long
term, can lead to complete discharge of the BATTERY, with possible irreversible
damage of the BATTERY PACK.
