Testing Lead Acid Batteries: Comprehensive Guide for Accurate
A fully charged 12V lead-acid battery should read around 12.6V or higher. A reading below 12.4V indicates partial discharge, while below 12.0V suggests significant discharge or potential failure. For 6V batteries, the corresponding values would be half of those for 12V batteries (6.3V for full charge, 6.0V or lower for discharge).

What is internal resistance in a lead acid battery?
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.
Do lead-acid batteries change internal resistance under different current?
Taking three full charging lead-acid batteries with a similar performance to discharge, as shown in Fig. 4, the change of internal resistance under different current for discharging has the same trend. Obviously, the battery internal resistance increases faster along with the enhancement of discharging current.
Does a lead acid battery change resistance compared to state of charge?
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.
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.
How long does a lead acid battery last?
Conductance, i.e., the reciprocal of internal resistance, which is expressed as mho or Siemens, has some kind of positive proportionate relationship with the battery capacity. 3 ~ 5 years under 2.3Vpc and 20°C floating charge condition. 3 ~ 5 years under 2.3Vpc and 20°C floating charge condition. 4. Operation of sealed lead acid batteries
Why should you use a battery internal resistance chart?
By using a battery internal resistance chart, you can easily monitor the internal resistance of your battery and identify any potential issues before they become a problem. Remember, a lower internal resistance indicates a healthier battery, while a higher internal resistance indicates a bad battery that needs to be replaced.
