Utilizing a four-wire method and a backlit LCD display, it supports multiple battery chemistries including Lithium-ion and nickel-hydroxide, ensuring reliable diagnostics in any lighting condition. Ideal for engineers and tech-savvy professionals who demand accuracy and versatility in battery testing. ## Description INTRODUCTION This Battery Internal Resistance Meter is an intelligent instrument which can be used for battery online measurements. It can be used to measure battery terminal voltage and internal resistance as well as to make normal resistance measurements. The internal resistance is measured with the international standard AC signal (1000Hz±10%) by means of four-wire method to eliminate the impact of the resistance of the test leads on the measured value, and the battery voltage can also be measured by the same connection method. It is applicable for measurements of internal resistance of Lithium-ion, nickel-hydroxide, lithium-manganese cells or assembled battery.

Nice LCD display. Works as advertised. I use a Lacrosse BC-700 for charge and capacity tests and this meter for battery internal impedance tests. This allows sorting and matching of AA flash batteries for minimum photography flash recycle time. For more stable readings, put the battery in a good metal battery holder and measure the impedance across the battery holder terminals.The meter does indicate a 1 when it is out of range, which is typical for all meters of this type.An instruction manual in English would be an improvement. Amazon provided the manual in English when requested. ### ⭐ This meter is complete junk *by F***D on March 18, 2021* I agree with three other reviewers. This meter is junk. Quality control was non-existent. The meter never worked, straight out of the box. Once a (verified good) battery is installed, the meter cycles through random numbers for about 5 seconds and then locks up displaying either 1 or-1. This happens on all switch positions, both volts and ohms. Turning the meter off does not reset the electronics. The meter will read 1 or -1 immediately after turning back on. I can reset the meter by disconnecting the battery and re-connecting it, but it again displays random numbers for about 5 seconds before permanently locking up again. This product is trash, and I will be returning it to Amazon for a refund. ### ⭐⭐⭐ These have a high failure rate. *by P***N on September 5, 2022* My first specimen lasted two and one half years, until it went kaput overnight. I was using it as usual one day, and at very next day, it was no longer a resistance meter. As failed, in all three resistance/impedance ranges: it would display a two digit number when open circuit (should be 'I' for infinity); and a three digit number on a conducting resistor. Even on shorted test leads, it displayed a bogus three digit number, higher than open circuit's two digits.Its circuit board has four turnable adjustable things (trimpots maybe). Having nothing to lose, I played with all four miniature dials: three didn't seem to do anything, and one of them tweaked least significant digit up and down by one count. (I don't remember which function was affected, volt or ohm.)I looked at it this way: thirty dollars spent for a tool which served two and one half years, is like twelve USD per year for rent/functionality. And it didn't become completely useless, just disabled: it is still a handy battery potential tester, a 50 V D.C. voltmeter. Every home should have a basic multimeter at this twenty-first century, but as most still don't: there is vacancy for battery potential meters, to be filled by these failed battery impedance testers. Pattern failure in this model of appliance is not an urgent escalating e-waste problem.While I am upset because it failed and doesn't seem easily fixable, I was satisfied enough with it, to order another. I did consider other options, and decided to just buy another one of these. My second specimen was dead on arrival: in a different way from how my first failed, this new-DOA was also only a DC-voltmeter. This DOA specimen displayed every resistance/impedance as zero. 0 Ω, in all three ranges. Ships from Amazon.com Sold by Amazon.com Customer Service Amazon.com, it was replaced five days later. This replacement (my third specimen) worked on arrival, but it lasted only two days. Two days after first use, it failed just like second specimen: measures anything as bogus 0Ω.I was completely satisfied with this measurement instrument, when it lasted two and one half years. Receiving two bad units in a row (one dead on arrival, one dead after two days) is not bad luck. There is a real problem here: either a major design oversight, or practically inexistent quality assurance.If I were Amazon.com: I would stop sale immediately and test each and every unit in inventory. If I were all-sun (Eastern Intelligent Meter Co.): I would retire the model EM3610, "go back to the drawing board" and re-engineer it. I want to see a new, hardness improved, model EM3611 Battery Internal Resistance Meter, with three year warranty. ## Frequently Bought Together - all-sun Battery Internal Resistance Meter / Battery Voltage Tester / Digital Battery Analyzer - JOREST 300Pcs Car Fuse Assortment Kit, 160 Mini Blade Fuses Automotive + 90 Standard Auto Fuses + 50 Micro Fuse + 1 Puller – for Car/RV/Truck/Motorcycle(2Amp 3A 5A 7.5A 10A 15A 20A 25A 30A 35A 40A) --- ## 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.it/products/33984596-allosun-battery-internal-resistance-meter-battery-voltage-tester-digital-battery](https://www.desertcart.it/products/33984596-allosun-battery-internal-resistance-meter-battery-voltage-tester-digital-battery) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-13*
