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.
Lead-acid batteries are highly sensitive to temperature. Testing should ideally be conducted at room temperature to ensure accurate results. Extremely high or low temperatures can skew the results of voltage, capacity, and resistance tests. To ensure optimal performance, it is recommended to perform battery testing at regular intervals.
