Draper 81164 12V Battery Tester – CCA, Cranking & Charging
The Draper 81164 is a 12V battery, cranking and charging tester for checking starting and charging faults properly. Instead of relying on a basic voltage reading, it tests battery condition, measured CCA, cranking voltage, cranking time and alternator output, giving a much clearer picture before replacing a battery, starter motor or alternator.
- Checks 12V battery health and measured CCA
- Tests starter cranking voltage and cranking time
- Checks alternator charging output and ripple
- Works with lead-acid, AGM flat plate, AGM spiral, gel and EFB batteries

Description
The Draper 12V battery diagnostic tool is a compact tester for checking battery condition, starter cranking performance and alternator charging output. It is the right sort of tool for Land Rover starting and charging faults where a normal voltage check does not tell the full story. A battery can show reasonable voltage at rest and still collapse under load, while poor charging output, voltage drop or a tired starter circuit can make a good battery look suspect.
What it tests
- Battery condition and measured CCA against the rating printed on the battery
- Cranking voltage while the engine is being started
- Cranking time, helping show whether the starter system is labouring
- Alternator charging output and charging ripple
For Land Rover owners
Land Rovers often end up with extra electrical loads, older cables, tired earth points and batteries that have had a hard life. This tester helps separate a weak battery from a charging fault or cranking issue, so parts are not replaced on guesswork. It is a better diagnostic tool than a basic multimeter for starting and charging checks because it tests the battery and system under more relevant conditions.
