## Frequently asked questions

### What does this tester check?

The battery condition from its voltage and, depending on the model, also its cranking capacity and the alternator charge. So you know whether charging is enough or the battery needs replacing.

### How do I know if my battery is OK?

Measure with the engine off and the battery at rest (a few hours unused): 12.6 V or more is a charged battery; about 12.4 V, 75 %; below 12.2 V it should be charged, and below 12 V it may be damaged. With the engine running you should see 13.8 to 14.7 V: a sign that the alternator is charging properly.
