Batteries should not be charged at very high currents to ensure long life. Unless ap-
proved by the manufacturer, the maximum charging current should be limited to
approximately C/10 (where C is the Ah capacity of the battery at 20 Hour Rate). Thus,
at the rated current capacities (50A for SEC- 1250UL and 25A for SEC-2425UL), the Ah
capacity of the battery that should be charged with the charger will be:
• 50A x 10 = 500 Ah for SEC-1250UL
• 25A x 10 = 250 Ah for SEC-2425UL
If battery with lower Ah capacity is charged at the full charging rate, the battery life is
likely to be reduced.
A provision has been made to reduce the maximum charging current to approximately
half: 25A +/- 1A for SEC-1250UL & 12.5A +/- 1A for SEC-2425UL. This mode is termed as
"Half Power Mode". This mode can be selected by pressing push switch marked "Half
Power Mode" (8). When selected, a Green LED marked "Half On" (5) will be lighted.
When "Half Power Mode" is selected, batteries with the following lower capacities can
be safely charged at C/10 charging rate:
• SEC-1250UL - 250 AH
• SEC-2425UL - 125 AH
