24V lead-acid batteries.
LED #2 OFF: 14.4V / 28.8V (2.4V / cell) - the standard charging
voltage suitable and safest for all lead-acid battery types.
TIP: If you are not sure of your battery's charging requirements, choose
this mode to avoid overcharging the battery.
LED #2 ON: 14.7V / 29.4V (2.45V / cell) - higher charging voltage
suitable only for specific sealed AGM (absorbed glass mat) flat plate or
spiral cell batteries.

IMPORTANT: Selecting 14.7V (for 12V batteries) or 29.4V (for 24V

REVERSE POLARITY / incorrect battery connection (LED #1a and
#1b flashing together) : The charger is electronically protected so no
damage will result, and the output will remain disabled until the
connections are corrected.
VOLTAGE SAFETY CHECK:
12V (#1a) flashing: a battery with voltage exceeding 16V is connected
/ battery may be 24V.
24V (#1b) flashing: a battery with voltage below 18V is connected;
battery may be 12V or it may be a deep discharged 24V battery.
Action: Physically check battery. If nominal voltage is 12V, disconnect
24V
battery and select 12V.
If nominal voltage is 24V, push and hold pushbutton switch. After 3
12V
seconds program will proceed to STEP 3.
The SAVE mode engages if the battery state of charge was less
than 50% or the battery was diagnosed as sulphated.
Charge time: Minimum 15 minutes, maximum 2 hours.
A recondition charge is applied; current is delivered in pulses to prepare
the battery to accept normal charge and increase state of charge above
50%.
: There are 2 different charge voltages for 12V /
