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. ## Frequently Bought Together - FNIRSI HRM-10 Voltage Internal Resistance Battery Tester，Battery Voltage Meter for Types of Batteries, Car Battery Tester, AAA AA Battery, 100V 200Ω, Digital Battery Analyzer for Household Automotive - FNIRSI DMT-99 Digital Multimeter 9999 Counts TRMS, Rechargeable Auto-Ranging Volt Meter with Recording and Monitoring Data Mode, Resistance, Capacitance, Diode, Frequency, NCV, Current Voltage Tester - FNIRSI LCR-P1 Transistor Tester, Mosfet Transistor Capacitor Tester, SMD Electronic Component Tester, Diode Triode Zener Diode Resistance Inductance Battery Test LCR Meter MOS PNP NPN ESR Meter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/638760265-fnirsi-hrm-10-precision-voltage-internal-resistance-battery-tester](https://www.desertcart.gr/products/638760265-fnirsi-hrm-10-precision-voltage-internal-resistance-battery-tester) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-29*
