Battery status Check.
Charge will not start with voltage under 2.0V
and more then 15,5V
For deeply discharged battery: current will
be 200-400mA at 16V for 5 seconds until
voltage reduces to 14V (2 hours max timeout)
If battery voltage is between 2.0V–6.0V a
limited current is delivered (0,8A) to re-
activate the battery elements, until voltage
rises above 6V (2 hours max timeout)
If battery voltage is between 6.0V-10.5V,
current will be at 0.8A and 2A for 5 seconds
alternately (4 hours max timeout)
After Pulse charge, If battery voltage reaches
10.5V–12.0V smartcharger will constantly
deliver 2A 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.
If battery level has reached 12.0V-13.6V. A
constant current will charge the battery until
it has reached 80% of the capacity.
SCS4: 1A (motorcycle mode), 4A (car mode),
4A (AGM mode).
SCS8: 2A (motorcycle mode), 8A (car mode),
8A (AGM mode).
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:
current <0.5A (motorcycle mode), current
<0.8A (car mode), current <0.8A (AGM mode)
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.
Battery maintained at 13,8V, a proper work
level to be kept always ready to go.
If voltage drops below 12V, smartcharger will
restart from bulk charge
