ZOYI ZT-XR1 Battery Internal Resistance Tester & True RMS Multimeter
A professional 2-in-1 diagnostic instrument combining precise milliohm battery internal-resistance testing with a high-resolution 25,000-count True RMS digital multimeter. Designed for battery maintenance, electronics repair, workshop testing and field diagnostics.
Professional Battery Health Testing
The ZOYI ZT-XR1 provides detailed battery-condition analysis alongside practical electrical measurement functions in one compact handheld device.
Its dedicated milliohm internal-resistance tester helps users assess lithium batteries, power banks, rechargeable AA/AAA cells, NiMH packs and many other rechargeable battery types.
Milliohm Resistance Testing Measure very low battery internal resistance to support accurate cell-condition assessment.
25,000-Count Display Provides high-resolution electrical measurements with a large, easy-to-read display.
True RMS Measurement Delivers dependable readings on conventional, non-linear and distorted electrical signals.
Smart Auto-Ranging Automatically selects a suitable measurement range for quick and efficient operation.
Why test internal resistance? A battery may show a normal voltage but still struggle to supply sufficient current. Increasing internal resistance can indicate ageing, degradation or reduced performance, helping users identify weak cells before they cause equipment problems.
