Professional Battery Tester Battery Internal Resistance Voltage Checker Tester With LCD Digital Display Electrical Instruments

Features:

*1. [Professional and Accurate Testing]: This battery internal resistance tester adopts 1KHz AC low resistance measurement technology and Kelvin four-wire detection, effectively eliminating the influence of line and contact resistance, realizing high-precision resistance and voltage detection of various types of small batteries, such as lead-acid batteries, lithium batteries, nickel-cadmium batteries, alkaline batteries, etc.  It is especially suitable for testing and maintenance of batteries on electric vehicles, and motorcycles.

*2. [Humanized Functional Design]: With a self-calibration function to ensure continuous accuracy, users can calibrate themselves according to their needs, and equipped with a filtering function and double alarm prompts, based on the preset upper and lower limits to automatically determine whether the battery’s internal resistance is qualified, and through the nice, qualified, poor three-level prompts to visually display the test results.  With the automatic resistance/voltage switching function, the measurement ranges from 0.000mΩ to 500.0Ω resistance and 0.000V to ±120V voltage.

*3. [3.2-inch Display & Convenient & Comfortable Operation]: A 3.2-inch display can simultaneously display the internal resistance and voltage values. The internal resistance measurement supports six automatic switches to simplify the operation process; the backlit display and LED flashlight function ensure it can operate in a dim environment. Its exquisite appearance and long-lasting design, combined with the humanized operation experience, make it a superior tool for battery testing and maintenance work.

*4. [Quality Material & Powerful Endurance]: The housing is made of ABS material and is fully wrapped with a TPR (thermoplastic rubber) design for a comfortable grip, providing shock and drop resistant features, ensuring that the instrument can still work stably in harsh environments.  Built-in a 1200mAh high-capacity lithium battery, with a short charging time of 2 hours, it can continue to work for about 8 hours, effectively protecting long uninterrupted on-site testing needs.

*5. [Wide Applicability]: With its professional and accurate test performance, humanized design concept, nice durability, and long endurance, this battery internal resistance tester is a useful partner for battery maintenance and troubleshooting.  Suitable for various battery testing scenarios such as automotive or small battery applications.
