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.

The resistance of modern lead acid and lithium-ion batteries stays flat through most of the service life. Better electrolyte additives have reduced internal corrosion issues that affect the resistance. This corrosion is also known as parasitic reactions on the electrolyte and electrodes.
The capacities of lead-acid batteries are very dependent on the temperature at which the battery is operating. The Capacity is normally quoted for a temperature of 25°C however, the capacity will reduce by about 50% at -25°C and will increase to about 10% at 45°C (figure 5).
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.
The nominal capacity of sealed lead acid battery is calculated according to JIS C8702-1 Standard with using 20-hour discharge rate. For example, the capacity of WP5-12 battery is 5Ah, which means that when the battery is discharged with C20 rate, i.e., 0.25 amperes, the discharge time will be 20 hours.
