5. LEAD BATTERY INFORMATION
The Lead battery consists of two single 12 volt batteries, connected in series to reach the voltage of 24 volts. They
are assembled in the factory, wired with the power cable and with the connector for connection.
NEVER leave the battery connected to the scooter when not in use.
An accumulation of hydrogen (in particular conditions) could cause very serious
accidents, with damage to things and people, including serious illness and
death.
Replace the battery that has finished its charge and discharge cycles (it is assumed that a variable number from
150 to 200 cycles can operate, depending on the type of use that follows): an exhaust battery, in addition to no
longer having energy storage capacity, inevitably produces hydrogen gas.
Dispose of the exhaust battery according to regional laws.
Extreme temperatures can affect the battery's charge capacity.
Leaving the battery in hot or cold environments, such as in a completely closed car in midsummer or midwinter, will
reduce the capacity and life of the battery itself. Always try to keep the batteries between 15 ° C and 25 ° C. Battery
performance is significantly reduced at temperatures below 0 ° C.
When battery performance is below 20% of normal, it needs to be replaced.
Use only batteries approved by SUEX s.r.l., charging them only with the relative approved chargers.
6. BATTERY DESCRIPTION
The lead BATTERY cannot be opened: it is sealed by the manufacturer and cannot be disassembled in any of its
parts. It is a unique piece and is a complete replacement.
Even when not in use, a fully charged battery slowly discharges due to the self-
discharge phenomenon; it is recommended to charge the batteries within 24
hours of use and at least once a month and, in any case, make sure that they
never completely discharge.
The lead BATTERY is made by connecting two single 12 volt batteries connected
in series.
NEVER try disassemble them.
The BATTERY is marked with a serial number and with the certification code,
marked on the top cover of the battery (see Fig. under).
In case of need, the number shown must be mentioned for requests for
assistance or for the supply of spare parts.

Main battery components (Fig.1) are:
•Battery (14),
•Charger connector cap and Battery’s charge socket (24).
7. BATTERY USE
The 71212 lead battery is used exclusively on the 7SEVEN Scooter (71207).
8. KNOW THE BATTERY CHARGE STATUS
8.1. CHARGE INDICATOR ON BOARD THE SCOOTER
On the right side of the Scooter there are two led: one blue and one red.
The BLUE LED lights on when the Scooter switch ins in ON position –both in LOW and HI speed.
The RED LED lights on when the battery is discharged and the residual autonomy is of few minutes : about 15
minutes in LOW speed and 10 mins in HI speed with a brand new battery pack.
Note the following:
•The charge indicator on the Scooter (or its display on an external device) provides an approximate indication of
the BATTERY charge status. Depending on the general condition of the BATTERY and its use, the various
elements that indicate the state of charge during use may not accurately reflect the residual state of charge of
the BATTERY.
•The indication of the state of charge is a relative indication, that is referring to the actual condition of the
BATTERY and not to that of a new battery (at maximum efficiency).

Rev.00 –10/11/2020

Code: 71212
•The BATTERY is subject to a natural decrease in its capacity over time due to various factors including the
main ones being age, how to use it and environmental conditions.
•Particularly heavy use or, on the other hand, too mild (with a few complete charge / discharge cycles),
particular environmental factors and battery damage can lead to:
•- early decay of its effective capacity
•- the reduction of its delivery duration for use
•- falsified readings of the state of charge.
•The same BATTERY in different environmental situations could therefore show different delivery durations.
•It is therefore important to charge the BATTERY 100% before each dive, that is, charge it, until the charger
marks the end of the charge.
•Do not use the charge indicator as a tool to program the dive or the duration of the dive during its course, but
program the dive with the usual safety parameters.
NOTE: SUEX s.r.l. declines any responsibility for the failure or incorrect evaluation of the residual battery
charge that has led to incorrect assessments regarding the autonomy of the Scooter.
9. BATTERY CHARGE
9.1. HOW TO CHARGE THE BATTERY
To charge, place the BATTERY in a safe place away from people and flammable objects and proceed as described
below.
USE ONLY THE APPROPRIATE BATTERY CHARGER
The battery should ONLY be recharged using the specific battery charger supplied (code 71219).
When the charger is not in use, disconnect it from the wall outlet and put it in its case.
CHARGE PROCEDURE
Carefully read the battery charger instructions manual.
Charge the battery before each use, allowing it to cool before inserting it into the Scooter; during this phase the
battery could release hydrogen which would inevitably accumulate inside the airtight scooter.
The accumulation of hydrogen (in special conditions) could cause accidents, with injuries to people and things.
Extreme temperatures can affect the battery's charging capacity.
Leaving the battery in hot or cold climates, such as a closed car in mid-summer or mid-winter, reduces battery
capacity and life. Always try to keep the batteries between 15 ° C (59 ° F) and 25 ° C (77 ° F). Battery performance
is significantly reduced in temperatures below 0 ° C (32 ° F).
Charging must take place in an appropriate place: covered and ventilated, away from flammable objects or liquids,
away from crowded rooms:
Disconnect the red connector that connects the battery to the engine. Remove the battery from the scooter (see
section "Removing and re-inserting the battery"). Connect the battery to the charger using the special red
connector.
DO NOT attempt to CHARGE batteries that are DAMAGED or leaking, or that are
RUSTY.
ENVIRONMENTAL CONDITIONS IDEAL FOR CHARGING
The charging temperature range is 0 ° C + 36 ° C. The ideal battery temperature at the start of the charging phase
is 20 ° C.
9.2. WHEN CHARGE THE BATTERY
Fully recharge the BATTERY:
•BEFORE EACH USE taking care to let the BATTERY cool before inserting it into the Scooter;
•At least once every 2 months;
•When the RED LED lights up (the charge level is less than 20%).
NEVER stop charging the battery: partial charges damage the battery and reduce
the autonomy of the battery itself!

Rev.00 –10/11/2020
Pag. 7/14
Code: 71212
The lead battery has no memory effect, it is advisable to recharge it often in order to extend the life of the
accumulators and ensure maximum autonomy.
9.3. NEW BATTERY, FIRST USE
A new battery operates at full capacity only after a few complete charging cycles (4-5): this for reasons related to
the activation of internal chemistry.
10. IMPORTANT WARNINGS ON THE BATTERY LIFE
BATTERY life (i.e. the total amount of energy that it can supply to the user device after a full charge) is a feature
that depends on numerous factors including environmental conditions, how it is used, how to charge and
discharge.
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).
11. EXTRACTION AND INSERTING OF THE BATTERY IN SCOOTER
Refer to user manual Scooter.
12. 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").
13. CUT OFF
The scooter integrates the electronic devices with the function of managing the safety of the cells that make up the
Lead battery.
Particular attention must be paid to the presence of the scooter 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 scooter and is
connected in series with 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.
IMPORTANT NOTE!
Excessive discharge can irreparably damage the battery.
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 theScooter 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.

Rev.00 –10/11/2020
Pag. 8/14
Code: 71212
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.
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.
No own cut off system is included into the lead battery.
13.1. 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;
Remove the battery from the Scooter;
Leave the battery to rest for at least 2 hours: this is the minimum time necessary, in this case, to allow the battery
to cool down and return to the waiting state for charging;
Connect the battery charging connector to the battery charger;
Proceed with charging, following the instructions in the battery charger user manual.
IMPORTANT NOTE!
Remember that when the cut off device intervenes, the Scooter inevitably stops
working.
This event must in no way be a source of danger for the diver, who will have
planned the diving activity taking into account that the use of the Scooter cannot
be considered as a system to safeguard one's life or to get out of situations. of
difficulty.
SUEX s.r.l. declines all responsibility following the intervention of the cut off system, in any situation, in
dangerous situations or in dives where the diver has (at his complete risk) entrusted his return to the
surface to the Suex Scooter.
Please note that the Scooter must be considered as an aid to diving and not as a means of rescue.
14. BASIC RULES FOR SAFETY
The BATTERY is the most delicate part of the underwater vehicle, it must be handled and stored scrupulously
following the instructions in this manual.
Handle batteries with care to avoid shocks or mechanical damage or leakage of liquid materials that can seriously
damage your health.

15. FIRE MANAGEMENT
Batteries must be stored and recharged in rooms free of flammable substances and far from people living places.
In the event of a fire, the BATTERY gives off dangerous liquids and vapors which can cause corrosive injuries and
burns and present an explosion hazard. It is important to implement all the procedures necessary for the insulation
and extinction of the fire or for the management of the event. The staff must know all the actions to be performed in
total safety and all means of individual protection must be available in accordance with current legislation.
Make sure that enough ventilation is available so that hazardous and potentially explosive vapors can be released.
Leave the room immediately in case of strong smoke development.
Contact a doctor in case of respiratory tract irritation.
Do not extinguish BATTERY fires with water: Co2 or powder fire extinguishers
are to be used.
Wait for the BATTERY to cool completely.
