How does it compare to load testing?
Traditionally, the battery industry has used the BCI Adjustable Load Test as a standard to determine a starting battery’s suitability for further service. This load test is a measure of the voltage drop when a load equal to one half of the battery’s CCA rating is applied for 15 seconds on a charged battery. To be considered good, the voltage must not drop below 9.6 volts at 70 deg F. To use a load tester accurately, the battery cannot be in a discharged condition and therefore must be charged, often requiring extended periods of time. In addition, the battery must be at room temperature, or the operator must compensate the resultant voltage readings to determine if the battery is good or bad. All this makes it inconvenient to load test batteries until the battery has already failed leaving the motorist stranded. In comparison, a Midtronics tester can be used to test the battery as received. This allows tests to be performed immediately without waiting from 8 to 24 hours for the battery
