Accurate once calibrated and it is easy to use. Also useful as a milliohm meter for checking resistance of battery connections and finding shorted components in electronics repair. Review: Brauchbares Heimwerker Messgerät - Das Messgerät wurde zügig innewrhalb der gesetzten Frist geliefert. Ausgepackt und zunächst gestaunt: das Gerät ist recht handlich und leicht. Begelegt sind die Messkabel, Ladekabel und Faltblatt. Gerät sogleich eingeschaltet und die ersten 5 Zellen durchgemessen, mit dem (erwarteten) Ergebnis, dass sie alle "tot" sind, während die "handelsüblichen Zellenprüfer" sie noch mit "Spannung vorhanden und im grünen Bereich" klassifizierten. Aber um jetzt das volle Leistungsspektrum des Geräts zu erkunden, musste das "Handbuch", sprich Faltblatt bemüht werden. Hier rächt es sich, dass man im "Schulchinesisch" nicht aufgepasst hat. Es gibt eine englische Übersetzung, doch letztlich ist der Informationsgehalt spärlich, allerdings sind auch die Funktionen des Gerät überschaubar. Für meine Zwecke reicht der Funktionsumfang, für andere Funktionen habe ich andere essgeräte. Endlich kann ich die "leistungsschwachen" Zellen eindeutig feststellen und entsorgen. ## Features - 【Portable】Internal resistance is an important indicator of battery performance. This handheld battery internal resistance tester can measure the internal resistance and voltage at the same time, adopting the Kelvin four-wire test clip, which better avoids the influence of contact resistance and wire resistance, and is able to carry out more accurate measurements. - 【Good Tool to Test Battery Performance】This internal resistance tester can help you figure out good and bad batteries. To process series-connected battery packs, it is necessary to match the capacity, internal resistance and voltage of the cells. It is suitable for testing lead acid, lithium ion, lithium iron phosphate etc. Good tool to test battery performance before you DIY battery packs. - 【PC Connection】You can connect this device to computer to analyse the data more conveniently. This voltage and internal resistance tester adopts intelligent control, LCD display, and implanted Kalman filter mathematical algorithm, which has the advantages of high precision, high efficiency, low cost, light weight, energy saving. - 【Wide Application】This battery voltage test meter is widely used in various battery production, cell phone, computer, electric vehicle and other battery maintenance, testing, scientific research laboratories and other occasions. It can also be used to measure the AC resistance of capacitors and low resistance value high precision resistance. - 【What You Get】1* internal resistance tester, 1 pair of probe, 1* user manual. We provide one year after sale service and lifetime technical support. Please feel free to contact us if you have any concerns. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D4567NZ7 | | Best Sellers Rank | 69,372 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 35 in Capacitance & Resistance Meters | | Brand | SURLABA | | Colour | Orange | | Compatible Devices | All devices that use the battery types that this tester can test. | | Country Of Origin | China | | Customer Reviews | 3.8 out of 5 stars 18 Reviews | | Included Components | Internal Resistance Meter | | Manufacturer | SURLABA | | Manufacturer Part Number | RC3563 | | Measurement Type | Ohmmeter and Voltmeter | | Measurement type | Ohmmeter and Voltmeter | | Model Number | RC3563-B | | Power Source | Battery Powered | | Power source | Battery Powered | | Product Warranty | 1 Year | | Specification Met | CE Marked | | Specification met | CE Marked | | Style | Internal Resistance Tester | | Style Name | Internal Resistance Tester | ## Product Details - **Brand:** SURLABA - **Colour:** Orange - **Power source:** Battery Powered - **Specification met:** CE Marked - **Style:** Internal Resistance Tester ## Images ![Battery Internal Resistance Tester, Portable Car Battery Analyzer 4 Wire Measure Voltage Ohm 1uΩ~200Ω/0~±100VDC for 18650, Lead Acid, Lithium Ion, Lithium Iron Phosphate - Image 1](https://m.media-amazon.com/images/I/61wzzG5AZQL.jpg) ![Battery Internal Resistance Tester, Portable Car Battery Analyzer 4 Wire Measure Voltage Ohm 1uΩ~200Ω/0~±100VDC for 18650, Lead Acid, Lithium Ion, Lithium Iron Phosphate - Image 2](https://m.media-amazon.com/images/I/71KFceXZ4TL.jpg) ![Battery Internal Resistance Tester, Portable Car Battery Analyzer 4 Wire Measure Voltage Ohm 1uΩ~200Ω/0~±100VDC for 18650, Lead Acid, Lithium Ion, Lithium Iron Phosphate - Image 3](https://m.media-amazon.com/images/I/71pjfkyXH4L.jpg) ![Battery Internal Resistance Tester, Portable Car Battery Analyzer 4 Wire Measure Voltage Ohm 1uΩ~200Ω/0~±100VDC for 18650, Lead Acid, Lithium Ion, Lithium Iron Phosphate - Image 4](https://m.media-amazon.com/images/I/61ikf+abd2L.jpg) ![Battery Internal Resistance Tester, Portable Car Battery Analyzer 4 Wire Measure Voltage Ohm 1uΩ~200Ω/0~±100VDC for 18650, Lead Acid, Lithium Ion, Lithium Iron Phosphate - Image 5](https://m.media-amazon.com/images/I/71jnMehsfCL.jpg) ## Available Options This product comes in different **Style Name** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Decent meter, works as intended *by A***H on 9 May 2025* Bought for building battery packs made from used cells and proved useful for matching cells.

Per quanto riguarda il tester in se funziona discretamente bene, le misure sono molto vicine a quelle di un Hioki serie BT, che non è per nulla male. Per quello che riguarda la connessione al PC e relativo programma posso dire che anche questo funziona, fatto decentemente con possibilità di apprezzare la curva Volt/resistenza su un plot X-Y. Non è assolutamente perfetto, per incomimciiare è in cinese con una sorta di traduzione fatta alla bene in meglio, rimangono le scritte cinesi alle quali segue l'inglese ma non su tutte le parole. Comunque come detto sopra funzionicchia, per quanto costa mi sento di promuoverlo, non è perfetto ma quattro stelle le merita tutte, se il programma fosse stato tutto in inglese avrebbe anche sfiorato le cinque stelle senza problemi. Io lo utilizzo per misurare gli shunt su moduli di potenza in attivo , cosa per me utilissima, nonostante il limite dei 100 volt mi permette di fare più del 90% delle misure di cui ho bisogno. ## Frequently Bought Together - SURLABA Battery Internal Resistance Tester, Portable Voltage & Internal Resistance Meter Measure Range 1uΩ~200Ω/0~±100VDC, Suitable for Lead Acid, Lithium Ion, Lithium Iron Phosphate XFUK-T9-RC3563-B - BOJACK 24Value 630pcs Aluminum Electrolytic Capacitor Assortment Box Kit Range 0.1uF－1000uF - DollaTek Transistor Multifunctional Tester TFT Diode Triode Capacitance Meter LCR ESR Meter NPN PNP MOSFET IR Tester --- ## 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.tn/products/644021270-battery-internal-resistance-tester-portable-car-battery-analyzer-4-wire](https://www.desertcart.tn/products/644021270-battery-internal-resistance-tester-portable-car-battery-analyzer-4-wire) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-29*
