AB101 12V Car Battery Tester

Check battery condition, cranking performance and the charging system with the AB101 tester.

Assess the 12V starting and charging system

• Battery-health testing helps guide maintenance decisions.
• Cranking tests provide information about starting performance.
• Charging-system checks help assess alternator operation.
• Support for flooded, AGM and gel batteries covers common 12V lead-acid types.
• A 100-2000 CCA range covers a broad range of rated starting batteries.
• Power from the connected battery avoids a separate charger for the tester.

Technical details

Supported rating standards include CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE and GB.

Select the correct battery type and rating before testing, and connect the clamps to clean terminals. A low charge level may require charging and retesting before deciding to replace a battery.
