Although batteries’ internal resistance would ideally be zero, internal resistance exists due to a variety of factors. Internal resistance increases as a battery degrades. On battery cell production lines, defective cells are detected by comparing the internal resistance of tested cells to that of known-good reference cells.
The battery internal resistance is usually measured in milliohms (mΩ), and measurement methods include AC impedance measurement (EIS), DC voltage drop method, LCR meter test, etc. Ohmic resistance: determined by the electrodes, electrolyte, conductive materials, etc. inside the battery, mainly affecting the instantaneous voltage drop.
With lead-acid batteries, monitoring internal resistance helps predict maintenance needs and detect sulfation or plate degradation. Across all battery types, internal resistance measurement ensures safe operation, extends lifespan, and supports optimal performance in both consumer and industrial applications.
Generally speaking, the greater the internal resistance, the worse the battery’s load capacity. High-power batteries (such as power batteries) have a smaller internal resistance, while low-power batteries (such as 9V batteries) have a relatively large internal resistance.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
