Overview

The leagend RT200 Battery Internal Resistance Tester helps you check battery condition by measuring internal resistance and voltage—two important indicators of battery performance and health. With a wide testing range of 1 μΩ–200 Ω and 0–100 V, leagend RT200 is suitable for testing automotive batteries, rechargeable batteries, lithium batteries, disposable batteries, and many other battery-powered applications.

Whether you are checking batteries at home, maintaining your vehicle, sorting rechargeable batteries, or troubleshooting a battery that is losing performance, leagend RT200 gives you accurate measurements you can save and review whenever you need them.

Key Features

Measure Internal Resistance to Check Battery Health

  • Internal resistance can increase as a battery ages or its performance declines. leagend RT200 measures battery internal resistance precisely, helping you identify batteries that may be deteriorating, underperforming, or no longer suitable for your application.

Wide 1 μΩ–200 Ω Resistance Testing Range

  • From very low-resistance battery connections to higher-resistance components, leagend RT200 provides a 1 μΩ to 200 Ω internal resistance measurement range for a wide variety of batteries and electrical components.

0–100 V Voltage Measurement

  • leagend RT200 measures voltage from 0 to 100 V, making it suitable for testing batteries and battery systems across a wide range of applications.

Test, Save & Review Results

  • leagend RT200 automatically saves measurement results, allowing you to compare readings over time and keep track of battery condition. It can store up to 160 groups of test results.

High Measurement Accuracy

  • With internal resistance accuracy of up to ±0.013 mΩ and voltage error of ±0.03 V, leagend RT200 provides precise measurements for battery condition checking and comparison.

Designed for Different Battery Types

  • leagend RT200 can be used with automotive batteries, rechargeable batteries, lithium batteries, disposable batteries, and other battery-powered devices within its supported measurement range.

Built-In Protection

  • Short-circuit protection, over-current protection, reverse-connection protection, and voltage protection help provide safer and more reliable battery testing.

USB Type-C Charging

  • The built-in 1450 mAh rechargeable battery provides convenient portable operation, while USB Type-C charging makes it easy to recharge the tester.

Automatic Power-Off

  • leagend RT200 automatically powers off after 5 minutes without operation, helping conserve its internal battery when the tester is left unused.
