ELECTRICAL Low Maintenance BatteryOCV- Open Circuit Voltage Test Battery voltage should be checked with digital multitesterReadings
capacity necessary to properly function in the electrical systemFor this reason, battery capacity or load test should be
conducted whenever poor battery performance is encounteredTo perform this test: 1Hook multitester to the battery in the same
manner as was done in the OCV testThe reading should be 12.8 volts or greater2Engage the starter and observe the battery
voltage while cranking the engineContinue the test for 15 seconds3During cranking the observed voltage should not drop below
9.5 volts4If the beginning voltage is 12.8 volts or higher and the cranking voltage drops below 9.5 volts during the test,
replace the battery OPEN CIRCUIT VOLTAGE STATE OF CHARGE 100 75 Charged 50 25 Charged LOW MAINTENANCE BATTERY 13.0V 12.80V
