## Overview

The FNIRSI HRM-10 is a handheld digital battery tester that accurately measures both voltage (up to 100V) and internal resistance (up to 200Ω) using a Kelvin four-wire method. Featuring a vibrant TFT HD color display, it supports a wide range of battery types from household AAA/AA to car batteries, with data storage and export capabilities for professional-grade battery diagnostics.

## Description

FNIRSI Voltage Internal Resistor, Battery Voltage Meter for Battery Types, Car Battery Tester, AAA AA Battery, 100V 200Ω, Digital Battery Analyzer for Household, Car

Review: The HRM-10 works quite well to check batteries. To utilize it to its fullest, the batteries should be checked when new or referenced to a new battery of the same type. A second use for the HRM-10 is to use it as a milli-ohm meter. Even with no battery connected, it will measure resistance in the milli-ohm range. It's great to check connections or check very low resistances.
Review: FNIRSI se ha estado volando la barda con los últimos dispositivos que está sacando. Este es uno de ellos. Excelente e inclusive tiene un modo sorteo por si lo usas en algún entorno de producción. Es muy preciso, y lo puedes ver también en los diferentes reviews y reseñas que hay en internet. Al ser un medidor en Kelvin es muy conveniente. Lo uso para mediciones de resistencia y para comprobación de resistencia interna de baterías. Sin detalle, recomendado.

## Features

- Voltage internal resistance battery tester: FNIRSI battery tester can automatically test the internal resistance and voltage value at the same time. The measured value can be used to determine whether the battery quality has decreased
- TFT HD colour display: the display has advanced colour HD technology and an excellent layout. Compared to conventional monochrome displays, it can display test results clearer and more vivid, which significantly improves the user's measurement experience
- Accurate measurement: uses a tailor-made Kelvin four-wire connection method to avoid wire and contact resistance and improve measurement accuracy. Users can also manually adjust the voltage and resistance range
- Wide range of applications: suitable for all types of batteries. Car battery tester, household battery. It supports historical records and export data tables of historical measurements. View 8 sets of voltage and resistance values to select batteries in batches
- 【LED Display Handheld Gauge】The resistance measuring range is up to 200Ω and the voltage measurement range is up to 100V. The device must not be used with a DC voltage of more than 100V. Do not use AC voltage under any circumstances

## Questions & Answers

**Q: Why can the measurement of internal resistance be a good or bad sign for a battery?**
A: The battery will be damaged during use, the capacity will decrease and the internal resistance will increase. The lower the internal resistance of the battery, the better the performance and the higher the load capacity.

**Q: Does the battery need to be fully charged for measurement?**
A: The internal resistance of a battery is usually different when it is fully charged and when it is low. When the battery is fully charged, the internal resistance is usually lower. When the battery is low, the internal resistance is usually higher.

**Q: Why are the measurements unstable?**
A: There is poor contact between the test clip and the battery, or there is a strong background noise.

**Q: Why is the measured internal resistance higher than the battery internal resistance?**
A: The internal resistance of a large capacity battery is very low. The internal resistance of the battery electrode or wire is often higher than the internal resistance of the battery.The clamp needs to be in the correct position to get accurate data.
