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.

Suitable Battery Types

  • Lithium-ion and lithium-polymer batteries
  • Rechargeable AA and AAA cells
  • NiMH rechargeable battery packs
  • Power-bank battery cells
  • Rechargeable tool and equipment batteries

25,000-Count True RMS Multimeter

In addition to battery testing, the ZT-XR1 operates as a full-featured True RMS digital multimeter for electronics repair, electrical maintenance and diagnostic work.

  • AC and DC voltage measurement
  • AC and DC current measurement
  • Resistance measurement
  • Audible continuity checking
  • Diode testing
  • Frequency measurement

Designed for Modern Electronics

True RMS capability helps provide reliable measurements on switching power supplies, chargers, inverters, automotive electronics and other systems that may produce non-linear or distorted signals.

The large backlit display, durable casing and ergonomic control layout make the ZT-XR1 suitable for workbench use, field service, education and portable diagnostics.

Typical Applications

Lithium and rechargeable battery testing
Power-bank and tool-battery diagnostics
Electronics repair and fault finding
Charger and power-supply testing
Workshop and laboratory testing
On-site service and mobile diagnostics
Battery Safety Do not test batteries that are swollen, leaking, physically damaged or excessively hot. Observe the correct polarity, prevent probe short circuits and follow the battery manufacturer’s safety instructions.
