Car Battery Tester For Cranking Amps Circuit

Posted on Jan 21, 2013

This circuit determines the cold cranking amps of a battery by first discharging the surface charge, then checking the internal resistance. This gives a more realistic measurement than simply measuring the instantaneous drop in voltage with a load. A constant-current source draws 2.5 A.
