Description of device and operation

The STC 612A Dynamic Battery Analyzer is a microprocessor controlled, host powered instrument designed to test and evaluate the standby charged condition and dynamic capabilities under load of a 6 or 12 volt, sealed, leadacid battery. It will also give an indication of the performance of the associated charging system. A static test is initiated by connecting the test leads of the instrument to the battery to be analyzed. The STC 612A monitors battery and charging circuit voltage and indicates the results on an easy to read LED display. Pre-load static test: Charging system connected: Charge voltage too high or open battery, charging normal, no charging voltage Battery only: Charge too high or open cell, normal charge, insufficient voltage to test or shorted cell A microprocessor controlled load test sequence is then operator initiated with the battery disconnected from the charging circuit. The load current is based on the battery’s rated AmpHour capacity. The battery condition is evaluated during the load test and latched at the termination. Dynamic load test result: Battery condition: Good, marginal, bad


Input Voltage from battery: 5-16VDC

Load Current: 30 ma. during static test, 3.5 Amps max. during dynamic test.

Static indicator transition voltages:

6V                       12V             INDICATION

<6.05              <12.10            too low to test

6.05-6.75       12.10-13.50    normal charged battery

6.75-7.10       13.50-14.20    normal charging voltage

>7.10             >14.20            overcharging/open battery


Dynamic load current: 1.0 to 3.5 Amps, dependent on A.H. selected.

Dynamic load time interval: 120 to 270 seconds, depending on battery voltage and A.H. selection (all intervals +/-1%)
