BATTERY CHARGING
ALWAYS REFER TO THE BATTERY MANUFACTURER’S RECOMMENDATION FOR
SELECTING CORRECT FLOAT AND EQUALIZE CHARGE VOLTAGES. FAILURE TO DO
SO COULD DAMAGE THE BATTERIES.
VERIFY THE POWER SUPPLY’S BATTERY CHARGER FLOAT AND EQUALIZE CHARGE
VOLTAGES. REFER TO THE POWER SUPPLY’S OPERATION MANUAL.
BATTERIES ARE TEMPERATURE SENSITIVE. DURING EXTREMELY COLD CONDI-
TIONS, A BATTERY’S CHARGE ACCEPTANCE IS REDUCED AND REQUIRES A HIGHER
CHARGE VOLTAGE; DURING EXTREMELY HOT CONDITIONS, A BATTERY’S CHARGE
ACCEPTANCE IS INCREASED AND REQUIRES A LOWER CHARGE VOLTAGE.
TO COMPENSATE FOR CHANGES IN TEMPERATURE, THE BATTERY CHARGER USED
IN THE POWER SUPPLY IS TEMPERATURE COMPENSATING. FLOAT AND EQUALIZE
CHARGE VOLTAGES WILL VARY DEPENDING UPON BATTERY TEMPERATURE.
IF BATTERIES APPEAR TO BE OVER OR UNDER-CHARGED, FIRST CHECK FOR
DEFECTIVE BATTERIES AND THEN VERIFY CORRECT CHARGER VOLTAGE SET-
TINGS.
BATTERY PREVENTIVE MAINTENANCE
BATTERIES SHOULD BE INSPECTED EVERY THREE TO SIX MONTHS TO ENSURE
OPTIMUM PERFORMANCE.
VISUALLY INSPECT BATTERIES FOR SIGNS OF CRACKS, LEAKS OR SWELLING.
CHECK BATTERY TERMINALS AND CONNECTING WIRES. BATTERY TERMINAL
CONNECTORS SHOULD BE CLEANED PERIODICALLY AND RETIGHTENED TO AP-
PROXIMATELY 60 INCH/LBS. SPRAY THE TERMINALS WITH AN APPROVED BATTERY
TERMINAL COATING SUCH AS NCP-2.
CHECK BATTERY VOLTAGES UNDER LOAD. USE A LOAD TESTER IF AVAILABLE.
DIFFERENCES BETWEEN ANY BATTERY IN THE SET SHOULD NOT BE GREATER THAN
0.3 VDC.
CHECK THE POWER SUPPLY’S BATTERY CHARGER VOLTAGES. REFER TO THE
BATTERY MANUFACTURER’S RECOMMENDATION FOR CORRECT CHARGE VOLT-
AGES AND THE POWER SUPPLY’S OPERATION MANUAL FOR CORRESPONDING
CHARGER SETTINGS.
NUMBER THE BATTERIES (1, 2, 3) INSIDE OF THE ENCLOSURE FOR EASY IDENTIFI-
CATION.
ESTABLISH AND MAINTAIN A BATTERY MAINTENANCE LOG.
