  • Product typeCar Charger
  • Tests 6 V and 12 V lead-acid batteries from 100 to 2000 CCA
  • Checks lithium starting batteries for accurate health data
  • 96 % accuracy via advanced conductivity technology
  • One-click waveform graphs voltage during cranking

6V and 12V battery tester for 100-2000 CCA

The BA301 works on 6V and 12V lead-acid batteries from 100 to 2000 CCA, covering regular flood, AGM flat, AGM spiral, GEL and EFB types. It also supports lithium starting batteries, making it suitable for cars, motorcycles, trucks, SUVs, RVs, ATVs, boats and yachts. Advanced conductivity technology and intelligent chips deliver up to 99.96% accuracy when measuring cold cranking performance, health state and ageing degree.

One-key waveform analysis and system tests

A single “Waveform” click plots voltage changes during ignition, showing current-voltage, maximum and minimum voltage on a graph for real-time fault tracking. The tool also tests the starter and alternator, identifying abnormal starting and charging conditions. Professional advice is generated from the measured data so you can decide whether to charge or replace the battery without visiting a repair shop.

For owners and shops needing broad voltage coverage

This tester suits users who need both 6V and 12V capability across a wide CCA range and multiple battery chemistries, including lithium starters. Buyers who only test a single voltage or a narrower CCA window may find a simpler device adequate. Those requiring integrated printing or wireless data export should look at other models.

Questions about this item

How high a cold-cranking-amp rating can the BA301 test before it hits its upper limit?

The tester handles lead-acid batteries rated from 100 up to 2000 CCA, so the ceiling is 2000 CCA.

Does the BA301 get hot or noisy during a full day of back-to-back battery and alternator checks?

The handheld analyzer has no fan or moving parts, so it runs silently and stays cool even with continuous use.

What power source does the BA301 need — does it plug into mains or run from the vehicle battery?

It draws operating power directly from the 6 V or 12 V battery under test, so no separate charger or mains adapter is required.
