4 FAQs about Battery cabinet resistance measurement

How to measure battery internal resistance?

The pulse load test is another method for measuring battery internal resistance. It involves applying a short-duration, high-current pulse to the battery and measuring the voltage response. The internal resistance can be calculated from the voltage drop during the pulse. 1.

What is battery internal resistance?

Battery internal resistance is a critical performance parameter that determines the runtime, power delivery, current capabilities, efficiency and health of a battery. Measuring the internal resistance allows you to analyze battery characteristics and performance for design optimization, production testing or periodic maintenance.

What are the principles of battery internal resistance testing?

Battery testers (such as the Hioki 3561, BT3562, BT3563, and BT3554) apply a constant AC current at a measurement frequency of 1 kHz and then calculate the battery’s internal resistance based on the voltage value obtained from an AC voltmeter.

Why is internal resistance measurement important for lead-acid batteries?

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.
