1. Introduction
This manual provides detailed instructions for the safe and effective operation of the ES 725 Battery/Starting/Charging Tester. The ES 725 is designed to test 6 and 12-volt batteries, as well as 12 and 24-volt charging systems. It performs a guided test sequence covering battery condition, cranking volts, and the overall charging system, including alternator voltage and AC ripple for bad diodes.
2. Safety Information
Always observe the following safety precautions when using the ES 725 Tester:
- Wear appropriate eye protection (safety glasses) and protective clothing.
- Ensure adequate ventilation when working with batteries, as they can produce explosive gases.
- Avoid sparks or open flames near batteries.
- Do not touch live electrical components.
- Keep the tester dry and clean. Do not expose it to rain or moisture.
- Refer to the vehicle manufacturer's service manual for specific safety procedures related to the vehicle's electrical system.
3. Package Contents
Verify that all items are present in the package:
- ES 725 Battery/Starting/Charging Tester unit
- User Manual (this document)
- Test leads with clamps
4. Product Features
The ES 725 Tester offers the following key features:
- Tests battery condition and the starting/charging system.
- Battery test results include State of Health percentage, State of Charge percentage, and actual CCA capacity.
- Removes surface charge prior to battery test for accurate results.
- 2-line LCD display available in 7 languages.
- CCA test range: 40 - 2000 CCA.
- Tests 6V and 12V batteries.
- Tests 12V and 24V charging systems.
5. Setup
Before operating the ES 725 Tester, ensure it is properly set up:
- Power Source: The unit is battery-powered. Ensure a fresh 9-volt battery is installed in the designated compartment.
- Connect Test Leads: Attach the red clamp to the positive (+) battery terminal and the black clamp to the negative (-) battery terminal. Ensure a secure connection.
- Initial Display: The LCD will power on and display the initial menu.
6. Operating Instructions
The ES 725 provides a guided test sequence. Follow the on-screen prompts.
6.1. Battery Test
- Connect the tester to the battery terminals as described in the Setup section.
- Select "Battery Test" from the main menu using the navigation buttons.
- Input the battery's Cold Cranking Amps (CCA) rating when prompted. This information is typically found on the battery label.
- The tester will automatically remove surface charge and perform the test.
- Results will display State of Health (SOH), State of Charge (SOC), and actual CCA capacity.
6.2. Cranking Volts Test
- Ensure the tester is connected to the battery.
- Select "Cranking Volts Test" from the menu.
- Follow the on-screen instructions to crank the engine for a short period (typically 5-10 seconds). Do not start the engine.
- The tester will measure the voltage drop during cranking and display the results, indicating the starter's performance.
6.3. Charging System Test
- With the tester connected, select "Charging System Test."
- Start the vehicle's engine and allow it to idle.
- The tester will measure the alternator's output voltage and check for AC ripple, which can indicate faulty diodes.
- Follow any additional on-screen prompts, such as increasing engine RPM, if requested by the tester.
- The results will indicate the health of the charging system.
7. Maintenance
To ensure the longevity and accuracy of your ES 725 Tester:
- Cleaning: Wipe the unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the tester in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Replacement: Replace the internal 9-volt battery when the low battery indicator appears on the display.
- Lead Inspection: Periodically inspect the test leads and clamps for damage. Replace if any wear or damage is observed.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tester does not power on. | Dead or improperly installed 9V battery. | Replace the 9V battery or ensure it is correctly installed. |
| Inaccurate test results. | Poor connection to battery terminals; incorrect CCA input; battery surface charge not removed. | Ensure clamps are clean and securely attached. Verify correct CCA input. The tester automatically removes surface charge, but ensure battery has rested for a few minutes if recently charged. |
| "Error" message on display. | Battery voltage too low; connection issue; internal fault. | Check battery voltage (if extremely low, tester may not function). Re-check connections. If problem persists, contact support. |
