Stage 2 - Absorption Stage ("Uo" Phase) is controlled by an internal timer circuit. Time
of 4 hours or 8 hours can be selected with the help of a pair of switches S3 & S4 of the
set of 4 DIP Switches (5). Check with the battery manufacturer for the optimum setting.

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 (80A for SEC- 1280UL and 40A for SEC-2440UL), the Ah
capacity of the battery that should be charged with the charger will be:
• 80A x 10 = 800 Ah for SEC-1280UL
• 40A x 10 = 400 Ah for SEC-2440UL
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: 40A +/- 1A for SEC-1280UL & 20A +/- 1A for SEC-2440UL. 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-1280UL - 400 Ah
• SEC-2440UL - 200 Ah
