The VDIAGTOOL BT310 is a 12V & 24V battery analyzer designed to provide technicians, professionals, and DIYers with critical information about battery health status and to quickly, easily, and accurately identify battery and charging problems. It applies advanced conductance testing technology and incorporates reverse polarity protection for safe operation.

Function Description:

The BT310 offers several key functions to assess the health and performance of vehicle batteries and charging systems:

Battery Capacity Test: This function determines the condition of the battery based on its rated value. It requires the engine and all other accessory loads to be off for accurate results. If the battery voltage is fully charged, it's recommended to turn on the vehicle headlights for 2-3 minutes until the voltage returns to normal values before testing. The test results provide information on voltage, State of Charge (SOC), Battery Resistance (Ω), State of Health (SOH), and Cold Cranking Amps (CCA), along with a recommendation to "CHARGE & RETEST" if needed. The device provides a reference table for 12V batteries, indicating "LIFE," "RESULT," "NOTE," and "LED" status (GREEN for Great/Normal, YELLOW for Caution, RED for Replace Needed).
Cranking Test: This test evaluates the battery's cranking ability by measuring cranking voltage and time. Similar to the capacity test, the engine and all other accessory loads must be off for accurate results. The tester displays the cranking time and cranking voltage, indicating whether the "CRANKING" is "GOOD." A reference table for 12V systems provides guidance on cranking voltage ranges, corresponding cranking ability (Good, Normal, Bad, Very Bad), and recommended actions (No Action, Keep Caution, Replace It Soon, Replace It Immediately).
Charge System Test: This function assesses the charging system's condition under loaded and unloaded statuses. For this test, the engine and all other accessory loads must be off initially. The instructions guide the user to turn on all loads and speed up the engine to 2000-2500 rpm before pressing "Enter." The test provides readings for Ripple, Loaded voltage, and Unloaded voltage, indicating if "CHARGING" is "GOOD." A reference table for 12V systems details battery voltage ranges and corresponding engine performance (Normal, General, Keep Caution, Inspection Immediately) for both "All Electric System Off (Depress Accelerator)" and "All Electric System On (Depress Accelerator)" scenarios. It's noted that bad batteries can affect the test results.
Language Setting: The device supports multiple languages, including English, Deutsch, Espanol, Lefrancais, Japanese, Portugues, Polski, Italiano, Magyarnyelv, Svenska, Slovak, Cesky, Neder Lands, and Pyccknn. Users can select their preferred language from the main menu.
About: This section likely provides information about the device's software version or other relevant details.

CCA Types: Supports various CCA types including CCA (Cold Cranking Amps, SAE & BCI), IEC (Internal Electron technical Commission Standard), EN (European Automobile Industry Association Standard), DIN (German Auto Industry Committee Standard), JIS (Japan Industrial Standard), and GB (China Standard). Users must choose the correct CCA TYPE according to their battery information.

Usage Features:

User-Friendly Interface: The device features a "MAIN MENU" with clear options for different tests and settings. Navigation is done using "Up" and "Down" buttons, "BACK" for returning, and "ENTER" for confirming selections.
Visual Indicators: The BT310 includes LED lights to indicate battery condition: a green light for good condition, a yellow light for warning, and a red light for bad condition.
Reverse Polarity Protection: This crucial safety feature prevents damage to the tester and battery if the clamps are connected incorrectly.
Power Source: The tester is powered solely by the vehicle battery, eliminating the need for external power.
Data Retention: The tool saves the result of the last test in memory for data review.
On-Vehicle and Off-Vehicle Use: The battery tester can be used both in and out of a vehicle.

Maintenance Features:

Cautions for Safe Operation: The manual emphasizes several safety precautions:
- Ensure battery terminals are clean, as grease and dust can lead to inaccurate results.
- Check the insulating layer of the clamps for damage, exposed wires, or disconnections to prevent electric shock.
- Wear eye protection when working around the battery.
- Test in a well-ventilated area, as vehicle exhaust contains toxic carbon monoxide.
- Keep hair, hands, clothing, and tester leads/cords away from moving blades and belts.
- Keep the tester out of reach of children.
- For safer use, connect the black clip (negative pole) first, then the red clip (positive pole). Avoid shaking the clips when connecting.
