As a battery ages, its internal resistance increases. This resistance is an important factor in determining the battery’s overall health and performance. Battery internal resistance can be measured with specialized equipment, and the results are often presented in a chart form.<\/p>\n

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.<\/p>\n What is the average internal resistance of a battery?<\/h2>\nThe average internal resistance of a battery varies depending on the type and size of the battery. 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.<\/p>\n What is the normal internal resistance of a 12v battery?<\/h2>\nThe 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.<\/p>\n What is the internal resistance of a bad battery?<\/h2>\n |
