Safety Information
To ensure your safety and prevent damage to the device or vehicle, please
carefully read and follow all instructions in this manual before use.
When operating the device, always verify proper testing procedures and
strictly adhere to the instructions provided. As automotive electrical
systems may vary, you must assess potential risks and ensure a safe
testing environment.
Always observe all safety warnings, use appropriate tools, and disconnect
power sources when necessary. Improper operation may result in person-
al injury, equipment damage, or voided warranty.
Safety Messages
Safety messages use standardized signal words to indicate hazard levels
and prevent injuries or equipment damage:
DANGER
Will result in death or serious injury if ignored
Indicates an immediately life-threatening hazard.
WARNING
Could result in death or serious injury if ignored
Indicates a potentially dangerous situation.
Safety Instructions
This manual covers known safety hazards, but cannot anticipate all possi-
ble risks. You are responsible for ensuring safe operating conditions and
procedures.
DANGER
• Always ventilate the service area when engine is running or use building
exhaust removal system if available
• Carbon monoxide is odorless and deadly - can cause loss of conscious-
ness or death
WARNINGS
• Only use the VDIAGTOOL BT500 for testing 6V, 12V, and 24V lead-acid
starting batteries (DC 9V-36V operating range).
• After charging, allow battery voltage to stabilize by turning on head-
lights for 2-3 minutes before testing.
• Always inspect clamp insulation for damage before use - never operate
with exposed wires or damaged housing.
• Avoid high temperatures, humidity, combustible environments, or strong
electromagnetic fields during use or storage.
• Never modify internal circuits - this may cause equipment damage or
personal injury.
• Wear safety goggles during testing to protect against flying debris.
• Maintain proper ventilation to prevent exposure to toxic fumes.
• Keep tester and accessories away from engine/exhaust components

BT500 6V & 12V & 24V BATTERY TESTER
1. Product Introduction
The VDIAGTOOL BT500 employs advanced conductance technology to
precisely measure battery CCA, SOH, and SOC, while diagnosing start-
ing/charging system faults. This all-in-one solution significantly improves
diagnostic efficiency for vehicle maintenance.
1.1 Product Functions
VDIAGTOOL BT500 features the following functions: battery test, crank-
ing test, charging test, test report print and other additional functions.
Battery test mainly aims to analyze the battery healthy status to calcu-
late the actual cold cranking capability of the battery and the aging
extent, which provide reliable analysis evidence for the test and mainte-
nance of the battery.
Cranking test is used to test and analyze the starting motor. Testing the
actual required cranking current and cranking voltage of the starting
motor is helpful to determine whether the starting motor works properly
or not. If the starting motor malfunctions, it may cause an increased
starting loaded torque; or rotor wear may increase internal friction of the
starting motor.
Charging test is to check and analyze the charging system, including
generator, rectifier, rectifier diode and etc., to find out whether the
output voltage of the generator is normal, whether the rectifier diode
works properly. And if the rectifier diode works abnormally, whether it
caused over charge of the battery. Over charge or incomplete charge of
the battery will cause quick damage to the battery and greatly shorten
the life of other loaded appliances.
Main Features:
1. Test all automotive starting lead acid storage battery, including regular
lead acid battery, AGM flat plate battery, AGM spiral battery, and Gel
battery, etc.
2. Detect bad battery.
3. Feature reverse polarity protection; reverse connection may not
damage the tester, the vehicle or battery.
4. Directly test the battery with loss of electricity; fully charge the battery
is not required before testing.
5. Testing standards cover the majority of world's battery standards, such
as CCA, BCI, CA, MCA, JIS, DIN, SAE.

• Discharge Voltage: A resting voltage below 11V (measured after 20+
minutes with ignition/engine OFF) indicates both immediate starting
difficulties and chronic battery aging requiring replacement, while
normal systems maintain ~12V.
• Starting Voltage: Represents the minimum voltage during ignition
(typically 7.5-9.5V). Sustained readings below 7.5V indicate depleted
battery capacity requiring replacement.
• Charging Voltage: Maintained at approximately 14V when the engine
is running, reflecting normal alternator charging operation.
Battery Status corresponding with Battery Voltage (Before Ignition)

Note: If the battery voltage remains at 11.9V after extended driving
despite having a properly functioning alternator, this indicates perma-
nent battery failure and requires immediate replacement.
