⚡ At a Glance
- • Test Coverage: 100–2000 CCA range; supports 12V lead‑acid types including AGM, spiral‑AGM, GEL and EFB; compliant with CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE and GB standards
- • Best for: DIY motorists and workshop technicians who need fast, reliable battery diagnostics
- • Not ideal for: Owners of vehicles with 24V electrical systems or non‑lead‑acid battery chemistries
Analysis checks charging voltage, internal resistance and ageing to indicate battery condition. Cranking and charging systems can be tested and results stored, while reverse polarity and overvoltage protections plus a three‑colour LED simplify result interpretation.
Quick, reliable health checks - with charging voltage, internal resistance and ageing analysis
Analysis measures charging voltage and internal resistance and assesses ageing status to determine battery condition. The tester compares measurements against standard thresholds to classify battery health.
Fast pass/fail indication helps decide whether a battery needs charging, replacement or further workshop diagnosis. Clear results reduce unnecessary workshop visits and save time.
Clear results for non-experts - with a three-colour LED status display
Three green, yellow and red LED lights represent good, charged or bad battery states. Numeric readings are supplemented by the LED band for quick interpretation.
Drivers and non-technical users can read battery condition at a glance without interpreting complex numbers. Useful for rapid roadside checks or pre-journey testing.
Broad vehicle compatibility - with a 100–2000 CCA range and multiple standard support
Designed for 12V lead‑acid batteries including AGM, spiral‑AGM, GEL and EFB and complies with CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE and GB standards. Test range spans common passenger and light commercial batteries.
