Lithium batteries are equipped with a battery management system (BMS), which can impede the start of
the charging cycle in some cases. In such cases, press and hold the Function button for 5 seconds after
setting the battery charger to lithium mode in order to initiate the charging procedure.
5 A - 12.5
A - 25 A
For standard and AGM batteries which have not been used for a long period of time and where the
battery acid has settled. CAUTION: Due to the high voltages attained during the charging cycle, the
battery must be disconnected from the vehicle for reconditioning. Reconditioning the battery with it still
connected to the vehicle could damage the vehicle electronics. (Only available in 12 V mode)

Use of the battery charger:
Connection
1. Connect the charger power supply unit to the socket.
2. Select the desired charging mode based on the battery.
3. First connect the red terminal to the positive terminal on the battery.
4. Then connect the black terminal to either the negative terminal on the battery or the ground terminal on the vehicle
chassis. (In the case of vehicles with a battery management system (BMS) on the negative terminal, please use the
ground terminal on the vehicle chassis. If in doubt, consult the vehicle manual.)
Disconnection
5. After using the battery charger, disconnect it from the mains socket first of all.
6. Remove the black terminal from the negative terminal/ground terminal on the vehicle chassis.
7. Then remove the red terminal from the positive terminal on the battery.

BATTERY CHARGER IS NOT PROTECTED AGAINST REVERSE POLARITY. RISK OF DAMAGE!
Battery analysis and error messages:
The charger is capable of checking the battery status before and during the charging procedure and displaying any errors
between the charger and the battery to be charged. This is done via a digital display on which the error code is shown. The
following displays may appear in case of faults during the charging procedure:
Display Reason Solution
The terminals of the output cables are not con-
nected to the battery correctly. Possible reverse
polarity.
Connect the clamps correctly and recommence
the charging procedure (see “Use of the charger”).
“Battery voltage too low. (Attempt made to charge
a 12 V battery with a charger set to 24 V.) Battery
voltage too high. (Attempt made to charge a 24 V
battery with a charger set to 12V.)
Check the voltage of the battery.
Ensure the settings are correct. Otherwise the
battery is likely faulty.
Battery charger faulty. Have the battery charger checked by a trained
specialist.
The battery is not capable of accepting charge
after a set time has elapsed.
Battery likely defective.
Battery reconditioning unsuccessful following a
complete desulphurisation cycle.
Battery likely defective.
The charging rate with the Supply function is
too high.
Reduce the charging rate.
Cable disconnected or short-circuited. Connect the terminals correctly and recommence
the charging procedure (see “Use of the charger”).
Battery completely short-circuited. Battery likely defective.

Charging cycles:
The charging cycles of the new battery chargers have been specially developed so as to optimise the charging of all conven-
tionally available batteries. The range of different technologies employed in the batteries commercially available today require
different charging characteristics to ensure correct and complete charging. The JMP Skan chargers extend the life of your
batteries as they guarantee the right charging cycle for each type of battery.
1. First diagnostics step: “Diagnostic I” (initial diagnosis) The charger analyses the battery’s charge level and the
voltage with which it needs to be charged.
2. First charging step: “Repair Mode” (desulphurisation) Charging with pulse current until the battery achieves the
optimum voltage and current values to commence the
second charging step.
3. Second charging step: “Initial Charge” (battery activation) Charging with reduced, constant current.
4. Third charging step: “Bulk Charge”
(charge with constant current)
Charging with constant current until maximum battery
voltage is achieved.
5. Fourth charging step: “Absorption Charge”
(charge with constant voltage)
Charging with stabilised current until current reaches
minimum values.
6. Fifth charging step: “Optimise”
(for Recon charging mode only)
I ntensive charging phase with constant current and increa-
sing voltage to boost the battery’s charging performance.
7. Second diagnostic step: “Diagnostic II”
(second diagnosis)
The charger checks the status of the charged battery.
8. Sixth charging step: “Float Mode”
(trickle charge with constant voltage)
Trickle charging with constant, reduced voltage.
9. Seventh charging step: “Trickle Mode”
(trickle charge with pulse current)
Trickle charging with pulse current (constantly available).
Safety precautions:
JMP Skan battery chargers are equipped with protective features to ensure maximum safety during operation and use of the
device.
• Complete protection against generation of sparks
