Standard Battery Charging Programs
The SCC-30AB provides 8 standard battery charging algorithms (programs) that are
selected with DIP Switches 2, 3, 4. These standard algorithms are suitable for Lead-Acid
batteries ranging from sealed (Gel, AGM, maintenance free) to flooded to L-16 cells
and Ni-Cd etc.
Table 6.1 below summarizes the major parameters of the standard charging
algorithms. Note that all the voltages are for 12V systems. For 24 V system, multiply
the voltages by 2.
• Consult the battery manufacturer / battery specifications & select the appropriate Algorithm.
• The unit is preset for Battery Type 1 (off-off-off) for a sealed / VRLA battery.
• For a generic non-sealed / vented / flooded / well cell Lead Acid battery, choose Battery Type 4.
Note: 1. All voltage values are at 25 ºC (77 ºF).
2. All the voltages given in the Table are for 12V Battery System.
For 24V Battery Systems multiply the voltage values by 2.

These are generic Lead-Acid – wet cell (Lead Antimony, Lead Calcium),
sealed AGM, sealed Gel Cell and Ni-Cd battery types.
This is the PWM Absorption Stage with constant voltage charging. The
"PWM Absorption voltage" is the maximum battery voltage that will
be held constant. As the battery becomes more charged, the charging
current tapers off until the battery is fully charged.
When the battery is fully charged, the charging voltage will be reduced
to 13.4 volts for all battery types. It will be 14.5V for Ni-Cd.
