BT.1000 Battery Analyser
Precision Battery Internal Resistance Analyser
The BT.1000 is a universal, high-accuracy analyser for testing the internal resistance, voltage, and temperature of lead-acid and lithium batteries. It uses the advanced AC 4-terminal method to eliminate contact resistance errors and also supports ESR testing of capacitors. Ideal for battery R&D, service centres, and industrial applications.
