Follow this steps to start the charge:
1. Connect the SMARTCHARGER to the battery (P.5),
then plug the AC power socket. The power status led
will turn on."
"
"
"
"
2. Select charging voltage by pressing the 12V / 24V
Button
3. If everything is ok SMARTCHARGER will start
charging directly. "
Use the “MODE” selection button to switch between
auto, AGM, Lithium, charging curve. "
"
"
"
When a charging curve or mode is selected, the
process will start.
4. SMARTCHARGER will check battery status before to
start. If the battery is ok the charge will start
normally (step 6), if not the device will try to recover
the battery (step 5).
5. If there’s something wrong with the battery
SMARTCHARGER will try to recover by the Rescue
mode."
Rescue can take 30 to 120 minutes."

NOTE
If the AC power socket is connected before connecting the
clamps to the battery, the error led will be turned on

Charge will turn to “Normal charge” (step 6) when
the battery is recovered. If battery can’t be recovered
the error led will be light up."
"
"
6. If everything is ok the “Normal charge” will start and
the charging led will light up.
"
7. The full charge / maintenance led will light up when
the battery is fully charged and now is in trickle
charge: If the voltage drops down SMARTCHARGER
sends current to the battery. SMARTCHARGER can
be connected for months without any trouble.
Using the Power Supply function:
The DC Power Supply function is not suitable to charge
batteries, so don’t use this function with a battery
connected.
Selecting this function:"
the device will deliver 27V at 12,5A and 13,5V at 25A.

NOTE
If the Lithium battery (LiFePO4) is deeply discharged and the
function UVP (under voltage protection) disconnects the battery
to prevent damages, the SMARTCHARGER will be not able to
charge. In fact this protection interrupts the connection between
battery and chargers/appliances and the SMARTCHARGER will
detect no battery.
To solve this problem press the “MODE” button for 5 seconds and
release until the “LITHIUM LiFePO4”led light will be turned on,
after that the charge will start normally.

8. Charging curves
The new “OPTICHARGE”firmware engineered by NDS
software team optimize the battery charge according
to the battery technology using optimal charging
parameters and constantly checking current and
voltage levels to let you have always ready to go and
healthy batteries. "
With OPTICHARGE you will have the best charging
experience ever created by NDS, the easiest way: just
p l u g t h e d e v i c e i n t o t h e p o w e r s o c k e t ,

SCM25 at 12V/25A - PHASES DISCUSSION
PRELIMINARY CHECK
Battery status Check. "
Charge will not start with voltage under 2.0V
and more then 15,5V
RESCUE
For deeply discharged battery: current will
be 500-800mA at 16V for 5 seconds until
voltage reduces to 14V (2 hours max timeout)
SOFT START
If battery voltage is between 2.0V–6.0V a 5A
current is delivered to re-activate the battery
elements, until voltage rises above 6V (2
hours max timeout)
PULSE CHARGE
If battery voltage is between 6.0V-10.5V,
current will be at 5A and 12,5A for 5 seconds
alternately (4 hours max timeout)
RECONDITIONING
After Pulse charge, If battery voltage reaches
10.5V–12.0V smartcharger will constantly
deliver 12,5A current to charge the battery
until it has risen over 12.0V. This stage will not
be carrying over 8 hours, otherwise the
battery is classified as defected.
BULK CHARGE
If battery level has reached 12.0V-13.6V. A
constant current 25A, will charge the battery
until it has reached 80% of the capacity.
ABSORPTION
CHARGE
If battery level is between 13.6V-14.4V (14.7V
for AGM), Smartcharger will switch to
Constant voltage mode: output current will
automatically adjust as according to the raise
of battery voltage. The charge will stop at
14.4/14.7V. Smartcharger will turn on the Full
charge icon led if the current reduces to 1.5A.
FINAL CHECK
Battery voltage is monitored for 1 minute. If
voltage has a dramatic drop down under
12.2V, the battery will be classified as
exhausted and the error led will turn on. If
voltage can be retained at 1 minute, then the
Maintenance mode will start.
MAINTENANCE
Battery maintained at 13,7V, a proper work
level to be kept always ready to go. "
If voltage drops below 12V, smartcharger will
restart from bulk charge

adjust as according to the raise of battery
voltage. The charge will stop at 14.4V.
Smartcharger will turn on the Full charge
icon led if the current reduces to 1.5A
FINAL CHECK
Battery voltage is monitored for 1 minute. If
voltage has a dramatic drop down under
12.2V, the battery will be classified as
exhausted and the error led will turn on. If
voltage can be retained at 1 minute, then the
Maintenance mode will start
MAINTENANCE
Battery maintained at 13,8V to be kept always
ready to go. Routine is: 2 minutes charge and
2 minutes pause for 12 hours, then stop. "
If voltage drops below 13,15V, the
maintenance mode routine will restart. "
