How does internal resistance affect battery performance?
High internal resistance can limit the effectiveness of batteries in applications requiring rapid bursts of energy, such as in power tools or flash photography. Monitoring internal resistance is crucial for understanding the safe operational limits of the battery. 6. Charging Rate The internal resistance of a battery also affects its charging rate.
