Test storage batteries, using electric testing instruments.
What does a Battery Tester do?
Tests storage batteries, using electric testing instruments: Sets dials on testing instruments according to battery voltage. Places positive and negative wired plugs on posts and intercell-connector terminals of corresponding polarity and observes indicator on instrument that measures resistance capacity in terms of pass or reject. Tests rejected batteries to determine specific defects, using voltmeter. Computes comparative figures and test data to determine deficiencies and attaches slip to battery indicating type of defect. May test battery assemblies on conveyor line. May test batteries used in field equipment and be designated Battery Tester, Field.
