6 FAQs about [Internal resistance lead-acid battery capacity]
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.
What is the average internal resistance of a battery?
For example, an average internal resistance for a lead-acid battery is around 10 milliohms, while a lithium-ion battery’s average resistance is around 50 milliohms. What is the normal internal resistance of a 12v battery? The normal internal resistance of a 12v battery can vary depending on the type and age of the battery.

The nominal capacity of sealed lead acid battery is calculated according to JIS C8702-1 Standard with using 20-hour discharge rate. For example, the capacity of WP5-12 battery is 5Ah, which means that when the battery is discharged with C20 rate, i.e., 0.25 amperes, the discharge time will be 20 hours.
How does internal resistance affect the performance of a battery cell?
