What is internal resistance in a lead acid battery?
As the capacity of lead acid battery decreased or the battery is aged, its internal resistance will be increased. Therefore, the internal resistance data may be used to evaluate the battery’s condition. There are several internal resistance measurement methods, and their obtained values are sometimes different each other.
Why are lead acid and lithium ion batteries resistant?
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.
How do you know if a battery has a high internal resistance?
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.
What happens when a lead acid battery is discharged?
When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate. After discharge, the concentration of sulfuric acid in the electrolyte is decreased, and results in the increase of the internal resistance of the battery.
How to make a lead acid battery?
