Load Battery Tester – How Does It Work?

Preparing the Load for Battery Testing

1. Check the condition of the battery tester and its cables. Ensure they are in good condition and have no mechanical damage.
2. Ensure a safe place for conducting the test. Avoid explosive gases and flammable materials!
3. You don't need to check the battery status – the BLT600S load will do it for you.
4. Your safety is paramount! Familiarize yourself with the warning signs on the load body and adhere to them.

 

Connecting the Load Tester to the Battery

1. Connect the connector to any battery terminal (post, screw, etc.) and apply the load tip to the other terminal. The test can be conducted without maintaining polarity. The clamp can be connected to either the positive or negative post of the battery.
2. Ensure the connections are strong and stable.
3. The device will automatically activate if the voltage of the tested battery is higher than 1V, and then conduct an efficiency test.
4. If the resting voltage of the battery is lower than 1V, you can manually activate the tester by clicking the left button on the voltmeter panel.
5. Before starting the load test, ensure the tested battery is fully charged.

 

Selecting Parameters and Load Range of the Load

1. On the tester, select the appropriate current load range depending on the battery capacity:
   • 12V: typically ranges 200A, 400A, 600A.
   • 6V: typically ranges 100A, 200A, 300A.
2. The range is selected using knobs on the load. The device has 3 circuits – each 200A for a 12V battery. When testing a 6V battery, the resistance of 1 spring is 100A.
   The first load circuit is permanently closed. By tightening the knob, you close the circuit, activating the next winding. This way, you increase the resistance by another 200A/100A.

 

Conducting a Basic Load Test

1. Press the device against the terminal.
2. Observe the voltage measurement on the display. The tester will subject the battery to the declared load.
3. Pay attention to the results:
   • For a functional 12V battery – the voltage displayed should drop and stabilize above 8.5V
   • If the battery is faulty, the voltage will drop towards 0V
4. The load test should not last longer than 10s.

 

Conducting a Semi-Automatic Load Test

1. Press the left button on the voltmeter, and a time lapse bar measuring 6 seconds will appear below the battery voltage on the display, which will start filling after pressing the tester.
2. Press the device against the terminal.
3. Observe the voltage measurement on the display. The tester will subject the battery to the declared load and inform with a double beep about the end of the test.
4. Stop pressing the load – you can disconnect from the terminal of the tested battery.
5. After pressing the right button on the battery tester display, a graphical voltage course, maximum and minimum measured voltage, and measured voltage difference will be presented.
6. The load test lasts 6s – after this time, the tester will inform about the end of the data collection stage. After exceeding 9s, an audible alarm is activated.

 

Turning Off the Tester and Disconnecting the Cables

1. Before disconnecting the BLT600S battery tester, remember that the resistive windings are hot. Touching them can cause burns. Take care of your safety!
2. Release the connection by detaching the load tip from the terminal, and then disconnect the clamp from the battery.
3. Place the device in a safe place. Avoid contact of the heated load surface with flammable gases and materials!
4. The device will automatically turn off 4 minutes after the last activity (pressing any button or performing a measurement). It is possible to manually turn off the tester by pressing the right button for a longer time (>1s).

Analysis of Results and Completion of Work

1. Compare the obtained results with the recommended values of the battery manufacturer.
2. If necessary, pass the battery for further diagnostics or replacement.
3. Store the tester in a dry and safe place, away from heat sources and moisture.

 

BLT600S Load Battery Tester – What Makes It Stand Out?

• Versatility: BLT600S allows testing of both 6V, and 12V batteries with a load of 100A /200A/ 300A (6V) or 200A /400A /600A (12V).
• Powered by two AA (LR6) batteries: Using popular AA batteries ensures easy access to power and saves time and operating costs.
• Automatic activation upon detecting voltage at the input: The tester automatically activates when connected to the tested battery, saving the user's time.
• Automatic Power Off (APO): This function saves batteries by automatically turning off the device after four minutes of inactivity.
• Self-test of the measurement system: The tester automatically checks its systems upon activation, ensuring correct operation and measurement reliability.
• Audible signaling: BLT600S informs the user about the start and end of the test, and also activates an audible alarm if the recommended time is exceeded.
• Bidirectional load testing: Allows testing regardless of how it is connected to the battery terminals, increasing work convenience.

 

Distinguishing Technical Parameters of the Load:

• Thick-walled aluminum body: High thermal capacity of the body allows for longer work without the risk of overheating the tester.
• Extended and low profile: Allows work in hard-to-reach places, increasing device stability.
• 25mm² connection cable: Ensures safe conduction of high current, increasing cable durability and device efficiency.
• Modular resistive springs: Thanks to the ability to tighten the springs, the user adjusts the load, allowing testing of different battery capacities.
• Unique serial number: Each tester has an individual number, which helps in device identification and increases security.

 

 

 

 

Distinguishing Software Features of the Load Tester:

• Advanced voltmeter module: Graphically presents the voltage course chart and records key parameters, such as no-load voltage, under-load voltage, and voltage drop, facilitating result interpretation.
• Precision and averaged modes: The tester offers the possibility of working in precision mode with 8 times per second refresh or in averaged mode (average of 4 measurements), stabilizing displayed results.
• Summary of parameters before shutdown: Before shutdown, the device presents a table with six key parameters, providing a full overview of the tester's work.
• Icons for operating mode and battery status: Visual indicators inform about the current operating mode and battery charge level, increasing user comfort.
• Graphical and audible test time signaling: A progress bar and audible signals inform about the 6-second test duration, then alert when the recommended time is exceeded. This aims to maintain repeatability of measurement procedures.

 

 

Distinguishing Mechanical Features of the Load Tester:

The BLT600S load battery tester is not just a manual load – it's a comprehensive solution that facilitates work in workshops.

SecureSpring Mechanism is an advanced spring system used in the BLT600S, designed for optimal and safe operation during battery testing.
A key element of this mechanism is a specially selected spring with precisely defined hardness, which:

• Minimizes pressure on battery terminals: The spring provides optimal resistance. Less force is needed to close the circuit, affecting the condition of battery terminals during measurements.
• Ensures smooth operation of the actuator: SecureSpring allows for smooth and stable movements during device operation, limiting the tip's slipping during work.
• Increases work comfort: Thanks to the appropriate spring hardness, the device's operation is more ergonomic, requiring less physical effort from the user.
• Increases device reliability: Thanks to SecureSpring, the tester operates more efficiently, longer, and with less risk of damage, translating into greater durability of the entire system.

This device increases diagnostic confidence and ensures precise measurements. Thanks to its advanced functions, solid construction, and attention to detail, BLT600S is indispensable in the daily work of professionals.
