OPERATION 
OPERATION 
A.  Preliminary 
 
Make sure the charger is installed and grounded as  
instructed in the INSTALLATION chapter of this 
manual. 
 
Maintain electrolyte level in the batteries to be 
charged, as instructed by the battery manufacturer.  
Because the volume of electrolyte expands during 
the charging process, only add water when the    
battery is at least 80% charged.  An amber light will 
be illuminated on the charger control panel when 
the battery is at or above 80% charge. 
 
Insure the battery size matches the charger. 
 
Battery number of cells must equal the number of 
cells stated on the charger data plate. 
 
Battery ampere-hour capacity must be within the  
ampere-hour range stated on the charger data 
plate. 
 
 
 
 
 
 
 WARNING:  EXPLOSION HAZARD – Do not 
 connect a battery to this charger if the  
 “Charge in Progress” LED is illuminated on  
 the charger.  Do not disconnect a battery  
 from this charger if the “Charge in Progress”  
 LED is illuminated or ammeter is indicating  
 charging current; otherwise, arcing and  
 burning of connector parts can occur or a  
 battery explosion may result.  Batteries       
 produce explosive gases.  Keep sparks,  
 flames, and cigarettes away.  Ventilate when 
 charging in an enclosed area.   Always shield  
 eyes using face shield and goggles when   
 working near batteries. 
   
  
 CAUTION:  The charging of a battery with 
 the incorrect number of cells or an ampere- 
 hour capacity outside the range stated on 
 the charger data plate will result in severe 
 over or under charging of the battery, 
 resulting in reduced battery performance 
 and life. 
 
 
 
 
 
 
 B.  Normal or Daily Charge   
 
 WARNING:  DO NOT connect a battery to 
 this charger if the “Charge in Progress” 
 LED is lit.  Do not disconnect a battery from 
 this charger while a charge is in progress;  
 otherwise, arcing and burning of connector 
 parts or a battery explosion may result.  
 Batteries produce explosive gases.  Keep  
 sparks, flame,  and cigarettes away.   
 Ventilate when charging in an enclosed  
 area.  Always shield eyes when working  
 near batteries. 
 
 
 1. Insure the battery size matches the charger  
 (Battery voltage and ampere hour capacity are 
 within nameplate information). 
 
 2.  Securely engage the battery and charger 
 connectors. 
 
 3.  After a five second delay (all LED‘s will be lit), 
 the charger will turn on.  The “Charge in  
 Progress” LED will indicate charging current. 
 
 4.  The  “80% CHARGED” LED will light when the 
 battery on charge reaches the 80% charged  
 voltage. 
 
 5.  The charger will automatically turn off and the  
 “Charge Complete” LED will light when the 
 charge has finished. reaching 80% charge.   
 The light will remain on until the battery is 
 disconnected from the charger. 
 
  
 NOTE: To disconnect battery from charger before 
 charge is complete, first press the “Manual 
 Stop” key, then disconnect the battery  
 from the charger.
