Digital Battery Tester 12/24V – Professional Vehicle Battery Analyzer for Lead-Acid Batteries

Unlike basic testers that only show voltage, this digital battery tester delivers a complete health assessment of 12V and 24V lead-acid batteries in under 3 seconds. It supports Flooded, GEL, AGM, and EFB types, making it suitable for cars, motorcycles, trucks, boats, RVs, and ATVs. With a wide CCA range of 100–2000 and multiple international standards, it provides accurate results for nearly any vehicle battery.

Highlights

• Tests 12V and 24V batteries: voltage, cranking, and charging system
• Works with Flooded, GEL, AGM, and EFB lead-acid batteries
• Supports CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, and GB standards
• Backlit LCD display for clear readings in any light
• Reverse polarity and overvoltage protection for safe operation
• Powered directly by the battery – no internal battery needed

In daily use

The tester is easy to operate: connect the color-coded clamps to the battery terminals, select the battery type and standard, and start the test. Within seconds, you get a clear indication of battery health, cranking performance, and charging system output. The backlit screen ensures readability even in dark engine bays. Its compact ABS housing and 70 cm cable with alligator clips allow comfortable access to battery terminals in tight spaces.
