Autel MaxiBAS BTAK Battery Tester Accessory Kit for BT608 / BT609

The Autel MaxiBAS BTAK Battery Tester Accessory Kit equips professional mechanics and enthusiasts with a DM100 digital multimeter and a 400A AC/DC current clamp for comprehensive vehicle electrical diagnostics. Designed for use with Autel’s MaxiBAS BT608  and BT609 battery analyzers, this all-in-one battery tester multimeter and clamp meter safely measures AC/DC voltage, current, resistance, and battery strength. The included 400A clamp meter handles currents from 20 mA up to 400 A without interrupting circuits, making it ideal for high-current tests like starter draw and alternator output. With this kit, technicians get a complete automotive electrical test suite: voltage and resistance readings, diode checks, and even parasitic drain tests in one package.

Key Features and Benefits

All-in-one Test Kit: Includes Autel’s DM100 digital multimeter, a 400A AC/DC inductive clamp, two alligator-clip battery leads, two insulated probes, and test leads – everything needed for battery and electrical diagnostics.

• Wide Measurement Range: Measures AC/DC voltage, current (20 mA–400 A), resistance, and diode checks. The clamp meter extends the BT608/BT609 capability to high currents, capturing waveforms for cranking amperage.

• Automotive Diagnostic Clamp Meter: The inductive clamp (Autel SA255) fits around conductors for safe current sensing. This lets you measure charging or starting currents without disconnecting wires.

• Battery and Charging Analysis: Works with BT608/BT609 to generate battery health reports. You can view numeric readings and waveform graphs (e.g. cranking current plots and leakage current tests) on the analyzer’s screen.

• Frequency Capability: Supports AC/DC frequency measurements up to 20 kHz for detecting high-frequency noise or parasitic draw.

• Durable Construction: Heavy-duty, heat-resistant test leads and robust clamp jaws ensure reliable use in workshops. All connectors are well-insulated and build to handle rough automotive environments.

• Warranty: Backed by Autel’s 1-year limited warrantyautel.com for peace of mind in professional use.

Compatibility and Kit Contents

• Compatibility: Designed exclusively for Autel MaxiBAS BT608 and BT609 battery analysis toolsautel.com. The BTAK connects to the analyzer via the Autel data cable so that readings from the multimeter and clamp display directly on the tool.

• Contents: DM100 Digital Multimeter ×1, 400A AC/DC Current Clamp ×1, Alligator Clip Leads (red/black) ×2, Multimeter Test Leads (red/black) ×2, Probes (red/black) ×2, and carrying case.

• Operation: Plug the multimeter and clamp into the BT608/BT609 home screen then lets you select voltage, current, resistance, or battery tests. Test results appear numerically and graphically on the analyzer. For example, measuring starter current will produce a cranking-amperage graph for detailed analysis.

Technical Specifications

Autel BTAK vs Standard Automotive Multimeter

In general, a standard digital multimeter (DMM) is optimized for voltage and low-current testing, while a clamp meter is specialized for high-current measurement. The table below highlights key differences between a typical automotive DMM and the Autel MaxiBAS BTAK kit:

Typical Use Cases

• Battery and Charging System Analysis: Measure battery cranking current, alternator output, and charging voltage. The BTAK adds a cranking-current graph to the BT608 / BT609 reports for precise starter performance analysis.

• Parasitic Drain (Leakage) Testing: Perform leakage current tests by clamping the battery cable and using the BT608 / BT609 battery tester app to detect unwanted drains.

• Electrical Circuit Troubleshooting: Check voltage drops, continuity and resistance in wiring harnesses, fuses, and components. The inductive clamp lets you measure AC noise or high current without disconnecting circuits.

• Alternator and Starter Testing: Quickly evaluate alternator current output under load and starter current draw during cranking. Both are displayed graphically on the analyzer for easy diagnostics.

• Preventive Maintenance: Use the kit during regular service to verify battery health and ensure wiring integrity, helping avoid no-start conditions or electrical faults.

Tips for Use

• Select Proper Clamp Range: Begin with the 40 A range on the clamp for smaller currents, then switch to 400 A for heavy loads (starter, alternator). Avoid overloading the clamp.

• Zero the Clamp: Before measuring DC current, press the DC Zero button on the clamp to remove any residual offset and ensure accuracy.

• Secure Connections: Attach the alligator clips firmly to the battery posts or test points. Ensure probes and clips are in good condition and fully inserted in the multimeter. Proper contact yields more reliable readings.

• Power Off Before Clamping: Always disconnect power before clamping onto a live wire if possible. The Autel clamp allows non-contact measurement, but it’s safest to remove power when installing the clamp.

• Use a Memory Saver: If you need to disconnect the battery (e.g. testing or replacement), connect an Autel OBDII Memory Saver (BTMS) first. This preserves vehicle computer settings and codes during battery change.

• Maintenance: Keep the clamp jaws and probes clean. Store all parts in the provided case to prevent damage. Check for firmware updates on the BT608/BT609 to ensure full compatibility.

Frequently Asked Questions

• Q: What devices are compatible with the Autel BTAK kit?
  A: The BTAK is specifically designed for Autel’s MaxiBAS BT608 (and BT609) battery analysis tools https://autolines.com.au/. It connects to the tool’s special accessory port so that all measurements display on the device screen.

• Q: What is included in the kit?
  A: The kit includes 1× DM100 Digital Multimeter, 1× 400A AC/DC current clamp (model SA255), 2× alligator-clip leads, 2× multimeter test leads, and 2× probes (red/black).

• Q: What measurements can I perform with this kit?
  A: You can measure AC/DC voltage, AC/DC current (up to 400 A with the clamp), resistance, continuity/diode checks, and battery conductance. In practice, it lets you fully test battery starting and charging systems. When used with a BT608/BT609, it even offers a built-in parasitic draw (leakage current) test routine.

• Q: Is a memory saver cable included?
  A: No. The BTAK kit itself does not include the Autel OBDII Memory Saver (part BTMS). The memory saver is a separate accessory used to preserve ECU codes when the battery is disconnected. It’s recommended when doing battery swaps or long tests.

• Q: What warranty is provided?
  A: Autel backs the BTAK kit with a 1-year limited warranty https://autolines.com.au/. This covers defects in materials and workmanship under normal use.

• Q: How is this different from a regular multimeter?
  A: Unlike a standalone multimeter, the BTAK kit is built to integrate with Autel’s battery analyzers. It adds a high-current clamp (up to 400 A) and communicates with the BT608/BT609 for graphing and logging. It effectively turns your battery tester into a full automotive diagnostic clamp meter.
