SCS4, SCS8 - LITHIUM PHASES DISCUSSION
PRELIMINARY CHECK
Battery status Check.
Charge will not start with voltage under 2.0V
and more then 14V
RESCUE
For deeply discharged battery: current will
be 200-400
m
A at 13,8V until voltage will be
>11,5V (2 hours max timeout)
CHECK
If battery voltage
＞
10.8V, smartcharger move
to next step
BULK CHARGE
If battery level has reached 13.8V. A constant
current (SCS4: 4A, SCS8: 8A) will charge the
battery when the current reduces to 0,8A
ABSORPTION
CHARGE
If battery level is between 13.8V-14.4V,
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 14.4V.
Smartcharger will turn on the Full charge
icon led if the current reduces to 0,8A
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 13,3V, the
maintenance mode routine will restart.
If voltage drops below 12V, the smartcharger
will restart from bulk charge
NOTE
THE red DOTTED box underlines the whole rescue
mode section that is activated only in case of battery low
performances.
