Impedance Testing: Comprehensive Health Assessment Lead-acid batteries degrade over time due to several factors, including sulfation, temperature fluctuations, and improper maintenance. Testing these batteries at regular intervals allows us to detect potential problems early, ensuring longevity and optimal performance.
Load Testing: Evaluating Real-World Performance Load testing simulates the real-world conditions a battery would experience during operation. By applying a significant load, this test assesses how well the battery can perform under stress. Apply a load equal to half of the battery’s Cold Cranking Amps (CCA) rating for 15 seconds.
To perform the load test, follow these steps: Charge the battery fully before testing. Connect the load tester to the battery terminals. Set the load tester to the appropriate load for the battery. Apply the load for 10 to 15 seconds. Record the voltage reading. Compare the voltage reading to the manufacturer’s specifications.
Common test methods include time domain by activating the battery with pulses to observe ion-flow in Li-ion, and frequency domain by scanning a battery with multiple frequencies. Advanced rapid-test technologies require complex software with battery-specific parameters and matrices serving as lookup tables.
