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.

Research shows that a typical lead-acid car battery may have an internal resistance of around 5 to 20 milliohms. Moreover, as temperatures drop, internal resistance can rise, impacting performance during cold conditions. High internal resistance can lead to decreased efficiency, reduced battery life, and compromised vehicle performance.

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.
Discharging a lead-acid battery. Discharging refers to when a battery is in use, giving power to some device (though a battery will also discharge naturally even if it''s not used, known as
High internal resistance has many implications. During discharge, the output voltage of the battery is affected by a high internal resistance that affects devices or systems relying on its battery performance.
High temperatures can accelerate chemical reactions and material degradation, while cold temperatures can slow down reactions and increase viscosity, both of which can contribute to increased resistance. Age:
High internal resistance can lead to poor performance and reduced lifespan of lead acid batteries. It may result in higher operational costs and increased battery failures,

This natural degradation causes an increase in the resistance of a cell''s internal conduction path. Valve-regulated lead acid (VRLA) batteries have other internal effects that also can cause loss of capacity and an associated increase in resistance. Internal ohmic measurements are intended to measure this change in resistance. A measured
3. Internal Resistance Testing: Diagnosing Sulfation and Aging. 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. Procedure:
A battery has internal resistance that grows over time with use. This resistance reduces power generation. lithium-ion batteries typically have lower internal resistance than lead-acid batteries. High internal resistance can lead to decreased battery efficiency, shorter operational life, and potential thermal runaway, posing safety

Lead acid has a very low internal resistance and the battery responds well to high current bursts that last for a few seconds. Due to inherent sluggishness, however, lead
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.
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
According to research by the University of Michigan (2020), lead-acid batteries have an internal resistance typically ranging from 0.010 to 0.020 ohms. They are commonly used in automotive applications, but their higher internal resistance can lead to inefficiencies during high-load situations. When the battery has high resistance, it can
The resistance of any battery (especially lead-acid and lithium-ion batteries) will stay flat throughout its lifetime. The corrosion is only compared to a parasitic reaction towards the internal resistance of a lithium battery. This is because
The use of instruments to directly or indirectly measure the internal resistance of the valve-regulated lead-acid (VRLA) cell has dramatically increased in recent years.

If you think about it, you''ll remember that the lead sulfate acts as an
Measuring the internal resistance of a lead acid battery can help determine its health and condition, and is a useful diagnostic tool for identifying potential issues. There are several methods for measuring the internal resistance of a lead acid battery, including the AC four-terminal method and the DC load method.

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.
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.
Lead acid has a very low internal resistance and the battery responds well to high current bursts that last for a few seconds. Due to inherent sluggishness, however, lead acid does not perform well on a sustained high current discharge; the battery soon gets tired and needs a rest to recover.
In this respect, nickel- and lithium-based technologies are more responsive than lead acid. Sulfation and grid corrosion are the main contributors to the rise of the internal resistance with lead acid. Temperature also affects the resistance; heat lowers it and cold raises it.
Several factors affect the internal resistance of batteries, including: The temperature of the battery affects its internal resistance. When the temperature is high, the internal resistance decreases, allowing for better current flow. On the other hand, low temperatures increase the internal resistance, leading to reduced current flow.
Alkaline, carbon-zinc and most primary batteries have a relatively high internal resistance, and this limits their use to low-current applications such as flashlights, remote controls, portable entertainment devices and kitchen clocks. As these batteries deplete, the resistance increases further.
