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.
References: Shukla et al. 1998. Rodrigues et al. 1999. The internal resistance of lithium-ion is fairly flat from empty to full charge. The battery decreases asymptotically from 270 mW at 0% to 250 mW at 70% state-of-charge. The largest changes occur between 0% and 30% SoC. The resistance of lead acid goes up with discharge.
The internal resistance of a lithium battery can be measured using specialized equipment like battery analyzers or dedicated internal resistance meters. These devices apply a small known current to the battery and measure the voltage drop across it to calculate internal resistance. How do you reduce internal battery resistance?
High internal resistance doesn't mean the battery is 'dead', just that it cannot maintain the voltage at high current that it could when new. The highest acceptable internal resistance is entirely dependent on the application. Rather than throw old batteries away I reuse them in devices that draw less current.
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.
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.
