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.
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.
For example, a good internal resistance for a lead-acid battery is around 5 milliohms, while a lithium-ion battery’s resistance should be under 150 milliohms. What is the average internal resistance of a battery? The average internal resistance of a battery varies depending on the type and size of the battery.
1. Construction of sealed lead acid batteries Positive plate: Pasting the lead paste onto the grid, and transforming the paste with curing and formation processes to lead dioxide active material. The grid is made of Pb-Ca alloy, and the lead paste is a mixture of lead oxide and sulfuric acid.
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.
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.

The internal resistance of the LABs increases at low temperatures, which lowers the voltage and energy density. Operation at sub-zero temperatures reduces the capacity, leads to incomplete battery recharging, and falls the battery cycle life. In addition, as the temperature decreases, it results in a reduction of electrolyte conductivity and diffusion coefficient. Sulfuric …

To illustrate this, consider a simple experiment with a AA cell. When connected to a 4 Ω resistor, the voltage across the battery terminals might drop from its VOC of 1.5V to around 1.45V. This drop is due to the battery''s internal resistance. Quote: "The internal resistance of a battery is like the resistance of a water pipe. The larger ...

Internal resistance or impedance measurements are a common method to assume the condition of a lead-acid battery. The readings could lead to predictions about the state-of-charge (SoC) and/or state-of-health (SoH) condition of a battery without the necessity of performing a full charge/discharge cycle. In practice, the readings

What is good internal resistance of battery? A good internal resistance for a battery depends on its type and size. Generally, a lower internal resistance indicates a healthier battery. For example, a good internal resistance for a lead-acid battery is around 5 milliohms, while a lithium-ion battery''s resistance should be under 150 milliohms.
The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge ...

Many people think that a battery''s internal resistance is high when the battery is fully charged, and this is not the case. If you think about it, you''ll remember that the lead sulfate acts as an insulator. The more sulfate on the plates, the higher the battery''s internal resistance. The higher resistance of a discharged battery allows it to ...
