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.
Capacity test is the only way to get an accurate value on the actual capacity of the battery. While used regularly it can be used for tracking the battery's health and actual capacity and estimating remaining life of the battery. When the battery is new its capacity might be slightly lower than specified. This is normal.
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.
