Battery Capacity Testing

Company Brief                              

Battery Internal Resistance Tester, also known as the Universal Charging Battery Internal Resistance Tester, is a measuring instrument used to measure the internal resistance, voltage, and temperature of lead-acid batteries, lithium batteries, and other charging batteries to determine the battery's health status. It can also be used to measure electrolytic capacitors.ESRParameter Gauge (for reference only). This gauge utilizes alternating4Terminal testing method measures battery internal resistance, which can be unaffected by the test wire, terminals, and battery voltage.Extreme.The between-contact resistance affects the accuracy of the measured values. It also features data storage, data retrieval, alarm, and automatic shutdown functions.
