Operation Manual

Battery Test
An automatic battery test is conducted immediately after the absorption stage.
The test monitors the voltage for 90 seconds to determine if the charge was
successful.
◆12V charger If the voltage is below 13.2 volts (fail), the charger will initiate the
Recondition stage.
◆12V charger If the voltage is above 13.2 volts (pass), the charger will proceed
to the final stage: Float.
◆24V charger If the voltage is below 26.4 volts (fail), the charger will initiate the
Recondition stage.
◆24V charger If the voltage is above 26.4 volts (pass), the charger will proceed
to the final stage: Float.
This recondition stage can recover batteries from a deeply discharged state
increasing performance and battery life.
RECOND- This mode is used to recover deep discharged flooded batteries
where you could expect a stratified acid (high acid weight in the bottom, low on
top). Check with battery manufacturer when in doubt. Use this mode with care,
because the high voltage will cause some water loss. 16V/32V is normally no
problem for electronics in 12V/24V system. Consult your supplier when in
doubt. Life of light bulbs will be reduced at higher voltage. Try to disconnect
light from the battery during this phase. Maximum effect and minimum risk for
electronics is achieved by charging a disconnected battery.
Float
The Float stage maintains the battery at 100% charge without overcharging or
damaging the battery. This means the charger can be left connected to the
battery indefinitely.
The battery charger has an 7-step fully automatic charging cycle. the cycle is
repeated infinitely. If the terminal voltage drops below a lower limit, the charger
automatically goes back to the beginning of the charging curve.
Recondition
The battery reconditioning function is initiated automatically in the case that the
battery fails the battery test (stage 5). Failing the battery test indicates that the
absorption stage was unable to fully charge the battery. The recondition mode
will then begin to introduce a low constant current for a period of 4 hours. Then
the charger will go into float charging mode.
