A multimeter reading means nothing under load. Our digital testing equipment measures true CCA, state of health and alternator output - so you know exactly what is going on before spending a cent.
True CCA under load
Measures real cranking ability vs rated CCA - not just resting voltage.
Alternator output and ripple
Confirms your charging system is not damaging your battery or failing to charge.
State of health percentage
Overall battery condition as a percentage - clear keep or replace recommendation.
Automotive battery test
Digital CCA and load test for all car, truck, SUV, van and ute batteries. Supports AGM, EFB and standard flooded.
FREE instoreAlternator and charging test
Tests alternator output voltage, current and ripple. Identifies charging system issues that drain batteries prematurely.
FREE instoreMarine battery test
Full CCA and capacity test for starting and deep cycle marine batteries including AGM and dual-purpose.
FREE instoreDeep cycle and AGM test
State of health and capacity testing for caravan, 4WD auxiliary and solar storage batteries.
FREE instoreLithium battery health check

Mobile service - callout fees applySlow or sluggish cranking
Engine turns over slowly on startup, especially in the morning.
Dim lights when starting
Headlights or interior lights dim noticeably when you turn the key.
Battery is 3 or more years old
Most batteries in NQ heat last 3-4 years. If yours is older, it is worth testing.
Battery warning light on
Dashboard battery or charging warning light has appeared.
Flat after sitting overnight
Battery drains overnight or after a few days without driving.
Had a jump start recently
Needed a jump start? That is a strong sign your battery is failing.
CCA and cold cranking ability
Quantifies real cranking power vs rated CCA with a clear keep or replace result.
State of health percentage
Overall battery condition as a percentage of original rated capacity.
Alternator output voltage
Confirms alternator is charging correctly - typically 13.8V to 14.4V under load.
Alternator ripple and diode check
Detects faulty diodes causing AC ripple - a common cause of early battery failure.
Internal resistance
Advanced health indicator. Rising internal resistance signals battery age and wear.
Starter motor draw
Measures current drawn on startup. High draw can indicate starter or wiring issues.
Open circuit voltage
Baseline state of charge reading. Combined with load test gives the complete picture.
