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
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. One way to measure internal resistance is by using the open-circuit voltage method. This involves measuring the
The Battery University defines the ideal internal resistance of a lead-acid battery as approximately 5-20 milliohms for fully charged batteries, depending on battery capacity and design. Lower resistance correlates with better performance.
Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents. These features, along with their low cost, make them attractive for use in motor vehicles
Below is a chart I found of the changing resistance of a lead acid battery compared to state of charge, however, the charge acceptance is higher when it is discharged compared to when it is charged. How does this happen with a higher resistance that gradually gets lower? I''m also assuming a constant charging voltage from an alternator.
Here is what I''ve found about the Lead Acid battery internal resistance: Lead Acid Battery – the lower the battery internal resistance the more the battery in good condition. To be exact, for a 12V Lead Acid Battery,

The lead–acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté''s design, the positive and negative plates were formed of two spirals o
The more sulfate on the plates, the higher the battery''s internal resistance. The higher resistance of a discharged battery allows it to accept a higher rate of charge without gassing or overheating than when the battery is near full charge. Near full charge, there isn''t much sulfate left to sustain the reverse chemical reaction. The level of
Resistance in lead acid batteries relates to various aspects: internal resistance affects charge acceptance, discharge capability, and overall efficiency. Higher resistance can lead to overheating and reduced performance. Monitoring resistance is
In lead acid batteries large, non-conductive, less soluble crystals of lead sulfate grow when the battery is left uncharged or partly charged, which increases the resistance of the battery. In
Another important indicator is the battery''s voltage. 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
@Ann Yes, if its a lead acid battery there should be permanent damage if you stored it for two years and never charged it. As you can see, all lead acid battery have a natural discharge rate between 1% to 20% monthly, so at 20% monthly your battery would be 100% discharged in just 5 months and that is using the worst case scenario discharge rate, at the
Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a

In lead acid batteries large, non-conductive, less soluble crystals of lead sulfate grow when the battery is left uncharged or partly charged, which increases the resistance of the battery. In lithium ion batteries the ion receptor channels in both the positive and negative electrodes can collapse or get clogged with lithium metal or corrosion
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries
2. Effects of High Resistance in Lead-Acid Batteries: High resistance in lead-acid batteries results in reduced current flow. This leads to decreased charging efficiency, which means that batteries may take longer to reach a full charge. A study by Johnson (2020) highlights that prolonged charging can lead to sulfation, where lead sulfate
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
Lead acid has a very low internal resistance, and the battery responds well to high current bursts lasting for only a few seconds. Due to inherent sluggishness, however, lead acid does not perform well with a sustained discharge at high current and the battery needs rest to recover. Sulfation and grid corrosion are the main causes of increased
Reduced Battery Life: High voltage resistance in lead-acid batteries leads to reduced battery life. Increased resistance can cause higher internal heat, leading to faster degradation of the battery plates and electrolyte solution. For example, a study by T. M. M. Al-Shahrani in 2020 indicated that batteries operating under high resistance conditions can lose
Cold temperature increases the internal resistance on all batteries and adds about 50% between +30°C and -18°C to lead acid batteries. Figure 6 reveals the increase of the internal resistance of a gelled lead acid

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.
Resistance in lead acid batteries relates to various aspects: internal resistance affects charge acceptance, discharge capability, and overall efficiency. Higher resistance can
If the voltage is too low, the battery will not fully charge, while if it''s too high, the battery will overcharge, leading to a reduced lifespan. Therefore, make sure to use the recommended charging voltage listed in your battery''s manual. Discharge Rates. The depth of discharge (DoD) of a lead-acid battery refers to the percentage of the battery''s total capacity
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.
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 accept a higher rate of charge without gassing or overheating than when the battery is near full 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.
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.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
High resistance causes the battery to heat up and the voltage to drop under load, triggering an early shutdown. Figure 1 illustrates a battery with low internal resistance in the form of a free-flowing tap against a battery with elevated resistance in which the tap is restricted. Low resistance, delivers high current on demand; battery stays cool.
