Product Description
The RC3563 Battery Internal Resistance Tester is a professional-grade digital instrument designed for accurate, real-time measurement of internal resistance and voltage for various battery chemistries. Featuring high-precision four-wire Kelvin test leads, it effectively eliminates lead and contact resistance errors to deliver reliable, laboratory-grade measurements.
Essential for quality control, battery sorting, and preventative maintenance, this tester instantly evaluates the health, capacity status, and degradation level of Lithium-ion, LiFePO4, lead-acid, nickel-metal hydride, and button cell batteries.
⚠️ Measurement & Safety Tip: Always ensure the battery terminals are clean and free of corrosion before connecting the Kelvin probes. Do not attempt to test batteries exceeding the maximum rated voltage input limit of the device to prevent internal circuitry damage.
Technical & Architectural Highlights
-
Four-Wire Kelvin Testing: Utilizes separate current and voltage sensing leads to cancel out contact resistance and ensure high measurement accuracy.
-
Simultaneous V & IR Display: Measures and displays internal resistance and DC voltage simultaneously on a clear, backlit LCD screen.
-
Wide Battery Compatibility: Suitable for testing Lithium-ion, Lithium Iron Phosphate (LiFePO4), Lead-Acid, NiMH, and alkaline cells.
-
Built-In Calibration & Sorting Modes: Features manual and automatic sorting functions with preset resistance thresholds for quick batch testing.
