Internal Resistance – The resistance within the battery, generally different for charging and discharging, also dependent on the battery state of charge. As internal resistance increases, the battery efficiency decreases and thermal stability is reduced as more of the charging energy is converted into heat.
Internal resistance in a battery refers to the amount of resistance that the battery's internal components, such as electrodes, electrolyte, and terminals, present to the flow of current within the battery. This resistance causes some of the electrical energy produced by the battery to be converted into heat, reducing
The internal resistance cannot accurately determine the battery capacity. There are also such testers, but you should not blindly trust their readings, since they do not measure the real capacity, but only calculate it. Not every battery is capable of delivering high starting current with low internal resistance.
The internal resistance varied widely and measured a low 155 mOhm for nickel-cadmium, a high 778 mOhm for nickel-metal-hydride and a moderate 320 mOhm for lithium-ion. These internal resistance readings are typical of aging batteries with these chemistries. Let's now check how the test batteries perform on a cell phone.
The resistance change between full charge and discharge is about 40%. Cold temperature increases the internal resistance on all batteries and adds about 50% between +30°C and -18°C to lead acid batteries. Figure 6 reveals the increase of the internal resistance of a gelled lead acid battery used for wheelchairs.
To illustrate this, consider a simple experiment with a AA cell. When connected to a 4 Ω resistor, the voltage across the battery terminals might drop from its VOC of 1.5V to around 1.45V. This drop is due to the battery’s internal resistance. Quote: “The internal resistance of a battery is like the resistance of a water pipe.
