Using the Battery Voltage Tester
Overview
This battery charger has a
Testing Sequence: There are five basic steps required to test the battery state of charge:
1.With the charger unplugged from the AC outlet, connect the charger to the battery following the instructions given in Sections 6 and 7.
2.Select the correct setting of the meter (6V or 12V) to match the battery to be tested.
3.Set the charge rate switch and the timer to the OFF position.
4.Plug the charger AC power cord into the AC outlet, following the instructions given in Section 8.
5.Read the voltage on the voltmeter.
Using the Alternator Performance Tester
Overview
This battery charger has a
Testing Sequence: There are five basic steps required to operate this unit as an alternator tester:
1.With the charger unplugged from the AC outlet, connect the charger to the battery following the instructions given in Sections 6 and 7.
2.Select the correct setting of the meter (6V or 12V) to match the battery to be tested.
3.Set the charge rate switch and the timer to the OFF position.
4.Start the vehicle and turn on the vehicle’s headlights. Read the voltage on the voltmeter.
Using the Battery Load Tester Feature
Load testing is the process of putting demand on a system or device and measuring its response.
Testing Sequence: There are five basic steps required to load test a battery.
1.Confirm that the charger is not plugged in.
2.Select the correct setting of the meter (6V or 12V) to match the battery to be tested.
3.Set the charge rate switch and the timer to the OFF position.
4.Connect the battery following the precautions listed in Sections 6 and 7.
5.Press the Load Switch to LOAD ON for 10 seconds while reading the voltmeter.
Green – Indicates the battery capacity is OK. The battery may or may not be fully charged. Check the specific gravity to determine the state of charge. If the specific gravity shows less than a full charge, check for an electrical drain on the battery or for possible charging system problems. Recharge the battery to full charge.
Yellow or Red, but the needle remains steady – Indicates that the battery capacity is not satisfactory. The battery may be either defective or not fully charged. Check the specific gravity of the battery to see which condition exists. If charging does not bring the battery up to a full charge, the battery should be replaced.
Yellow or Red, but the needle continues to fall – Indicates the battery may be defective or rundown. Release the load switch, and note the voltmeter reaction. Voltage recovery into the green or above within seconds indicates a defective battery. A slow recovery indicates a rundown condition. For best results, check the specific gravity of the battery.
