Equalize Cycle (BCA Only)
If a battery is left discharged for too long, sulfate crystals can form on its internal electrode 
plates. This interferes with their conductance reducing battery’s capacity and charging speed.
Your battery charger can perform an Equalize Cycle to correct this condition. An Equalize Cycle 
ensures all the cells of the battery are fully charged; deliberately overcharging the battery at 
a low current (approximately 10% of its normal output) until it reaches the unit’s programmed 
Equalize Voltage. The charger maintains the battery at that voltage for three hours after which 
time the Equalize Cycle ends and the battery charger resumes normal operation; maintaining 
the battery at the oat voltage. 
DANGER: AN EQUALIZE CYCLE CAN ONLY BE PERFORMED IN A WELL VENTILATED 
AREA!
Hydrogen gas is a normal by-product of the Equalize Cycle and is explosive at concentrations 
greater than 4% of the local atmosphere.
CAUTION: A BATTERY TEMPERATURE SENSOR MUST BE INSTALLED AND USED! 
Heat is a normal by-product of the Equalize Cycle and excessive heat will damage the battery 
bank. The battery temperature sensor must be connected and installed to allow the unit to 
monitor the temperature and ensure it is within safe operating limits. 
TO PERFORM AN EQUALIZE CYCLE:
1.  Connect and install the supplied Analytic Systems Battery Temperature Sensor. See 
Installation for more information. 
2.  Push the Equalize Button on the front panel. On some units, this button is recessed to 
prevent accidental operation; a ballpoint pen can be used to access it. 
3.  If the unit is not currently charging a battery, the EQUALIZE LED will glow red and the 
Equalize Cycle will begin. 
4.  If the unit is currently charging a battery, the EQUALIZE LED will blink red. Once the 
charging cycle ends, the CHARGING LED will shut off and the EQUALIZE LED will glow 
red and the Equalize Cycle will begin. 
5.  Three hours later, the Equalize Cycle will end. The battery charger will automatically 
resume normal operation maintaining the battery at the oat voltage.
