TA-22 TestMate Auto & Truck
The TA-22 TestMate Auto & Truck is a powerful, easy-to-use diagnostic tester designed to evaluate 12V automotive and truck batteries and their supporting electrical systems. Engineered for accuracy and reliability, it provides clear LCD results and printable reports — helping workshops and fleet operators make confident service decisions.
Note: The TA-22 is designed for automotive and truck batteries only. It is not suitable for motorcycle batteries.
What the TA-22 Can Test
The TA-22 offers comprehensive diagnostics across multiple configurations:
- 12V battery testing (standalone battery)
- 12V vehicle system performance testing
- 24V vehicle system testing (two 12V batteries connected in series)
- Charging system analysis
- Cranking performance evaluation
For vehicles with:
- Two 12V batteries in series (24V system) – Test each battery independently for accurate results.
- Multiple 12V batteries in parallel – Test each battery separately.
Key Features & Benefits
- Powered directly by the vehicle battery
- Activates automatically when voltage is above 9V
- Clear LCD screen display
- Guided step-by-step testing process
- Multiple international battery rating standards supported
- Adjustable CCA input for precise comparison
- Displays:
- Battery voltage
- State of Health (SOH%)
- Cranking voltage
- Charging system performance
- Clear recommendation (e.g., Good Battery / Recharge & Retest)
- Printable test reports
12V Battery Test – Accurate Health Analysis
For best results, disconnect the battery from the vehicle circuitry before testing, as connected systems can influence readings.
Testing Process:
- Inspect the battery for visible defects (swelling, cracks, damage).
- Connect:
- Red clamp to positive (+)
- Black clamp to negative (–)
- Battery voltage is displayed.
- Select:
- 12V Battery Test
- Battery type (e.g., Flooded Lead-Acid)
- Applicable rating standard
- Enter the battery’s specified CCA rating (e.g., 650 CCA).
- Start the test.
The TA-22 compares the measured performance directly to the rated specification, providing:
- State of Health (%)
- Clear recommendation
If the result is anything other than Good Battery, recharge and retest.
Cranking Test – Starting Performance Check
This test evaluates battery performance during engine start.
Procedure:
- Connect clamps to installed battery.
- Start the engine when prompted.
- The tester automatically performs the analysis.
Important Indicator:
- A cranking voltage below 9.6V indicates:
- Weak battery, or
- Underperforming charging system
Results are clearly displayed and can be printed for records.
Charging System Test – Complete Alternator Analysis
This multi-step test evaluates the vehicle’s charging performance under both unloaded and loaded conditions.
Steps:
- Connect clamps before starting the engine.
- Select:
- Charging Test
- Vehicle system voltage (12V or 24V)
- Secure the tester away from moving engine parts.
- Start the engine and follow on-screen instructions.
During testing:
- Unloaded phase: Turn off all manually controlled systems.
- Loaded phase: Turn on all lights and electrical systems.
At completion, the TA-22 provides a comprehensive charging system assessment with a printable report.
Built for Workshop Accuracy
To ensure the most precise results:
- Test batteries independently in multi-battery systems.
- Disconnect battery from vehicle circuitry when performing standalone battery tests.
- Confirm battery voltage is above 9V before testing.
Ideal For
- Automotive workshops
- Truck service centers
- Fleet maintenance facilities
- Professional technicians
The TA-22 TestMate Auto & Truck delivers fast, reliable battery and system diagnostics for modern vehicles, helping professionals reduce misdiagnosis, improve service quality, and increase customer trust.
