The SM8124Plus Battery Internal Resistance Tester is an intelligent instrument specifically designed to measure various battery resistance. It measures battery resistance in off-line mode and also features battery voltage measurement capability.
When measuring battery resistance, the instrument utilizes the international standard 1KHz constant current and four-contact/four-wire system to eliminate the effects of lead resistance and contact resistance, ensuring accurate measurements.
This tester is suitable for internal resistance measurement of various single cells and assembled batteries including lithium-ion, nickel metal hydride, zinc manganese, and lead-acid batteries, enabling quick assessment of battery quality.
