⚡ At a Glance
- • Test Accuracy: Advanced conductance testing delivers precise battery and alternator readings in seconds
- • Best for: Garage technicians and home mechanics who need fast, reliable diagnostics
- • Not ideal for: Users who require integrated workshop management software or full vehicle diagnostics beyond battery systems
Conductance testing supports 12V and 24V batteries with a 100–2000 CCA range. A 2.4-inch colour LCD shows clear, easy-to-read results.
Fast, reliable diagnostics, with advanced conductance testing
Conductance testing measures the electrical conductance of battery plates to infer state of health and cranking ability, producing results without a lengthy charge cycle. The method delivers readings in seconds and includes cranking and charging system checks.
Quick checks make it straightforward to spot failing batteries or alternator faults before they cause a breakdown. Rapid results save time compared with returning a vehicle to a workshop for initial diagnosis.
Wide vehicle and battery compatibility, with 12V/24V and 100–2000 CCA support
Compatibility covers both 12V and 24V systems and a CCA range from 100 to 2000, and supports regular flooded, AGM flat plate, AGM spiral, gel and deep cycle chemistries. That range matches most passenger cars, light commercial vehicles and marine batteries.
Useful across cars, motorcycles, boats, SUVs, trucks and even golf carts, reducing the need for multiple testers. One unit suits workshop routines and roadside checks alike.
Clear readouts and user safety, with a 2.4-inch colour LCD and protection features
A 2.4-inch colour LCD improves legibility in direct sunlight and low light, while eight language options and a detailed manual aid straightforward use. Reverse polarity protection guards against incorrect connections.
Readable menus and safety measures reduce user errors and speed up testing for both professionals and DIYers. Multilingual support makes the tester accessible in mixed-language workshop environments.
