The resistance of modern lead acid and lithium-ion batteries stays flat through most of the service life. Better electrolyte additives have reduced internal corrosion issues that affect the resistance. This corrosion is also known as parasitic reactions on the electrolyte and electrodes.
The internal resistance of a lead-acid battery can provide insights into potential problems such as sulfation, a common cause of battery failure. High internal resistance can indicate that the battery is nearing the end of its life or has been poorly maintained.
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.
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.
A fully charged lead-acid battery should have a voltage of around 12.8 volts. If the voltage drops below 12.4 volts, the battery needs to be recharged. Internal resistance is also an important factor to consider. A battery with high internal resistance will have difficulty delivering power, which can result in poor performance.
High internal resistance can indicate that the battery is nearing the end of its life or has been poorly maintained. Use an ohmmeter or a specialized battery tester to apply an AC signal across the battery terminals. The device will measure the internal resistance in ohms.
