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.

Customer ServiceMany 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. The higher resistance of a discharged battery allows it to

The largest changes occur between 0% and 30% SoC. The resistance of lead acid goes up with discharge. This change is caused by the decrease of the specific gravity, a depletion of the electrolyte as it becomes more watery. The resistance increase is almost linear with the decrease of the specific gravity.
One of the urgent requirements of a battery for digital applications is low internal resistance. Measured in milliohms, the internal resistance is the gatekeeper that, to a large extent, determines the runtime. The lower the resistance, the less restriction the battery encounters in delivering the needed power spikes.
For example, an average internal resistance for a lead-acid battery is around 10 milliohms, while a lithium-ion battery’s average resistance is around 50 milliohms. What is the normal 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.
Lead acid batteries typically have an internal resistance around 20 milliohms. Thanks Crosstalk for replying me. You said 20 mOhms for a typical lead acid battery. But what is the typical ? 20, 40 or 100Ah ? (12V). I'm not 100% sure on this, but I don't think that the battery's capacity matters.
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.
