• Load Testing
• Load Testing shall only be performed as a bench test.
• While on open circuit, place 100 amp load across each battery for a period of 30 seconds.
• Measure and record end of discharge (E.O.D.) voltage at 30 seconds.
• Calculate average and compare results against value of 10.95 for Type PRC 12120X E.O.D.@ 30
Seconds and 100 amp load.
• If calculated average E.O.D. of group is observed as being normal, identify and replace individual
batteries with values that are 10% less than the group average.
• General Equipment Requirements.
• Digital voltmeter- 3 1/2 digit, minimum 0.25% accuracy.
• Load tester (100 amps) with digital voltage readout, minimum 0.25% accuracy.
• Thermometer- thermocouple, contact type, 1 0 C accuracy.
• Battery Date Coding.
• The manufacturer stamps the Negative terminal post of the battery, with the month and year date
code.
• Shelf life is based on normal storage temperature conditions, 66 o F ~ 90 o F, and requires recharging
every 6 months from the last full charge date.
