BU-201: How does the Lead Acid Battery Work?

Choosing a low voltage limit shelters the battery, but this produces poor performance and causes a buildup of sulfation on the negative plate. A high voltage limit improves performance but forms grid corrosion on the positive plate. While sulfation can be reversed if serviced in time, corrosion is permanent. (See BU-403: Charging Lead Acid) Lead acid does not lend itself to fast charging

6 FAQs about [Lead-acid battery has low voltage and large internal resistance]

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

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.

Can a lead acid battery fail?

The battery may also fail as an open circuit (that is, there may be a gradual increase in the internal series resistance), and any batteries connected in series with this battery will also be affected. Freezing the battery, depending on the type of lead acid battery used, may also cause irreversible failure 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.

What is the 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. However, a healthy 12v lead-acid battery should have an internal resistance of around 3-5 milliohms. What is the internal resistance of a bad battery? A bad battery will have a significantly higher internal resistance than a healthy battery.

What happens if a battery has a high internal resistance?

If the internal resistance increases on one of the battery cells this means the battery will supply less current and will probably heat up more than it should. There is a direct connection between the battery internal resistance and the C-rating of the battery pack. Typically the high C-rating batteries have lower internal resistance values.
