Introduction
The EDIAG BM310 is a compact and easy-to-use 12V car battery and alternator tester designed to quickly assess the health of your vehicle's battery and charging system. This device provides clear indications of battery status and alternator performance through its intuitive LED display, helping you identify potential issues before they lead to vehicle breakdown.
Safety Information
Always prioritize safety when working with vehicle batteries. Please read and understand the following safety precautions:
- Ensure the vehicle engine is turned off before connecting or disconnecting the tester, unless performing an alternator test as instructed.
- Wear appropriate personal protective equipment, including safety glasses and gloves, to protect against battery acid and electrical hazards.
- Avoid contact with battery terminals and cables while the engine is running or the battery is connected.
- Keep the tester away from water, oil, and other liquids.
- The BM310 features a reverse protection function to prevent damage from incorrect polarity connection. However, always double-check connections to ensure proper operation and safety.
- Do not attempt to disassemble or modify the tester. Refer all servicing to qualified personnel.
Product Overview

Setup
The EDIAG BM310 is designed for quick and simple setup. It is compatible with all 12V automotive and motorcycle batteries.
- Ensure the vehicle is turned off before connecting the tester for a battery check. For an alternator check, the engine will need to be running later.
- Connect the red alligator clip to the positive (+) terminal of the 12V battery.
- Connect the black alligator clip to the negative (-) terminal of the 12V battery.
- Once connected, the tester will automatically power on and begin its assessment.

Operating Instructions
The BM310 provides two primary functions: Battery State Check and Alternator State Check.
1. Battery State Check
With the tester connected to the 12V battery and the engine off, observe the "Battery State" LEDs:
- Full (Green LED): Indicates the battery is fully charged.
- Middle (Orange LED): Indicates the battery is moderately charged.
- Low (Red LED): Indicates the battery charge is low and may require charging.
- Check before Charge (Green LED): If this LED is lit, it suggests the battery could be charged. If the voltage drops to 10V, the battery may be damaged and cannot be charged.

2. Alternator State Check
To check the alternator's performance:
- Ensure the tester is correctly connected to the battery.
- Start the vehicle engine.
- Accelerate the engine to approximately 2000 RPM.
- Observe the "Alternator State" LEDs:
- Good (Green LED): Indicates the charging circuit is functioning correctly.
- Fault (Red LED): Indicates a charging system error. If this light is lit, the alternator voltage may be too high, which could damage your battery.

Maintenance
To ensure the longevity and accurate performance of your EDIAG BM310 tester, follow these simple maintenance guidelines:
- Cleaning: Wipe the device with a soft, dry cloth after each use. Do not use abrasive cleaners or solvents.
- Storage: Store the tester in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it in its original packaging or a protective case when not in use.
- Cable Care: Inspect the cables and clamps regularly for any signs of wear, fraying, or damage. Replace if necessary.
- Avoid Drops: While built with durable ABS material, avoid dropping the device to prevent internal damage.
Troubleshooting
If you encounter issues with your EDIAG BM310, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No LEDs light up when connected. | Incorrect connection; Battery completely dead; Faulty clamps/cables. | Ensure correct polarity (+ to +, - to -). Check battery voltage with a multimeter. Inspect clamps and cables for damage. |
| "Fault" LED for Alternator State is lit. | Alternator charging system error; Over-voltage. | Consult a professional mechanic to diagnose the alternator or charging system. |
| "Low" LED for Battery State is lit. | Battery is discharged. | Charge the battery. If the "Check before Charge" LED does not light up after charging, the battery may be damaged. |
| Inconsistent readings. | Poor connection; Dirty battery terminals. | Ensure clamps are securely attached. Clean battery terminals to remove corrosion. |
