What is the internal resistance of a lead-acid battery?

For a lead-acid battery cell, the internal resistance may be in the range of a few hundred mΩ to a few thousand mΩ. For example, a deep-cycle lead-acid battery designed for use in an electric vehicle may have an internal resistance of around 500 mΩ, while a high-rate discharge lead-acid battery may have an internal resistance of around 1000 mΩ.

What is a good internal resistance for a 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.

What is the internal resistance of a battery cell?

Measuring the internal resistance of a battery cell can be useful for determining the performance of the cell and identifying any issues that may affect its performance. For a lithium-ion battery cell, the internal resistance may be in the range of a few mΩ to a few hundred mΩ, depending on the cell type and design.

Why does the internal resistance of a battery increase?

The internal resistance of a battery increases as the state of charge decreases. This is because as the battery discharges, the chemical reactions that produce the electrical energy become less efficient, which increases the resistance of the battery. What is the typical internal resistance of a 1.5V battery?

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.

What is the internal resistance of a nickel-metal-hydride (NiMH) battery cell?

For a nickel-metal-hydride (NiMH) battery cell, the internal resistance may be in the range of a few hundred mΩ to a few thousand mΩ.
