technician a says that the 3-minute charge test is performed after a battery has failed a load (capacity) test. technician b says that if the battery voltage is below 15.5 volts at the end of the 3-minute charge test, the battery is probably sulfated. who is correct?

Technician A's statement is correct - a 3-minute charge test is performed after a battery has failed a load (capacity) test.What is a 3-minute charge test?In a standard 3-minute battery test, a battery is charged at a rate of 30 to 40 amps. If the charging voltage is more than 15.5 volts, the battery is severely sulfated and most likely beyond repair.At a battery temperature of 70°F or 21°C, the load should be applied for 15 seconds, and the voltage shouldn't go below 9.6V. A 3-Minute Charge Test can be used to check for a sulfated battery if a battery fails the load test but the Open Circuit Voltage (OCV) is over 12.4V.The main reason is to check whether the battery fails or not.To know more about sulfated batteries and the 3-minute charge test, please follow this linkhttps://brainly.com/question/13264273#SPJ4
