o
Equalization Charge is an additional charge stage injected here and is
invoked via the following methods:
 A MODE containing a flooded USBattery battery, such as battery type
US1800,
and
 Every 15
th
charge cycle is started, and/or
 If the A.C. Cord is plugged/unplugged 15 times, and/or
 The ‘Menu Select’ Button is held depressed for 10seconds when A.C.
power is applied
o
While in this specific Charge Stage, the Yellow/Green LEDs will flash
alternately.
o
This Charge Stage locks in for a period of 2hrs to 4hrs and can terminate at
any time after the minimum 2hr period when a series of dv/dt measurement
records have been satisfied.

STAGE FIVE or SIX – FLOAT/MAINTENANCE (STANDBY)
o
Green (Charged) LED illuminates. Battery is fully charged and no further
‘charging’ action is occurring. Charger is now in standby and monitoring the
battery and passage of time. Charger may now also be left connected to
battery, indefinitely.
o
If the Green LED flashes, it is signaling an abrupt change in the previous
charge cycle (but not an error) and may require additional attention
according to the flash rate:
 Slow Flash: Charge cycle ended via peak voltage detection in the Top-
Off Charge stage.
 Medium Flash: Charge cycle ended via peak voltage detection in the
Equalization Charge Stage.
 Fast Flash: Charge cycle ended via Maximum Safety Timer time-out.
 Modified Flash Pattern – Flash-Flash-Flash-OFF: When the Battery
Temperature Cable is connected and a maximum battery temperature
was reached, charging was terminated early.
o
If any of these flashing patterns occurred, check all of the equipment or
vehicle’s inter-wire connections from receptacle to batteries, including inter-
battery wiring for loose and/or dirty or worn or burned connections. Also,
check each battery for possible replacement of that battery and battery pack.

STAGE SIX or SEVEN – RECYCLE CHARGE STAGE
o
While in Standby Mode (Stage-5 or 6: Float/Maintenance) and if a
substantial load were to be applied, charger will reset; thereby, automatically
initiating a new charge cycle routine and restoring battery to full capacity.
o
If while charging, the charger finds an abnormal charge condition, it will
attempt to shut down and indicate the ‘Condition’ by flashing any one of the
LEDs. Refer to the ‘Troubleshooting’ section for a description of the Charge
Error Condition.
