It supports a variety of battery types, including 18650 li-ion and lead-acid, with a maximum discharge voltage of 15V and current of 3A. Featuring a resolution of 0.001A, this tester provides real-time results and allows for manual adjustment of termination voltage, making it an essential device for professionals and enthusiasts alike. ## Description Power supply voltage: DC4.5-6V (micro USB interface)Working current: <=70mADischarge voltage: 1.00V-15.00V, resolution 0.01VTermination voltage range: 0.5-11.0VSupport current through: maximum 3.000A, resolution 0.001AMaximum voltage measurement error: 1% + 0.02VMaximum current measurement error: 1.2%+-0.002AMaximum battery capacity range: 9999Ah (1Ah=1000mAh)Board size: 50mmX37mm Instructions:(1) The battery under test is fully charged first;(2) Connect the positive pole of the tested battery to the input positive pole, the negative pole to the input negative pole, and give the tester micro USB through the working power;(3) Press the “OK” button to press the “+” or “-” to set the termination voltage in the battery voltage display state. After setting, press “OK” to start the test.(4)When the battery voltage reaches the set termination voltage, the tester cuts off the load control switch, and the display data stays on the capacity (Ah) and flashes rapidly with the corresponding indicator light. The capacity displayed at this time is the actual discharge capacity of the battery. Move "OK" to terminate the flashing to make the data display stably. Press the "OK" button again to return to the power-on state. You can replace the battery test in the next section.Package Included:1 x Battery Tester1)Q:how many 18650's can these charge connected in parallel? A:You can use this for only one battery .2)Q:I'm making a bluetooth speaker. Which end do I connect the bluetooth amp to?A:If you are using a spare battery, connect its positive terminal to the "+" negative terminal to the "-". 3)Q:Am I reading correctly that this has low voltage cut off?A:Yes, that is what is described in the item. ## Features - External load capacity of the battery and other tests - Tools, single-function, by controlling the load off and get real-time integrated discharge current capacity results - Maximum support 15V 3A discharged through the discharge voltage and current, itself does not discharge - Support current through: maximum 3.000A resolution 0.001A - Automatically identify and develop appropriate battery termination voltage can also be manually adjusted ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | qianzhi | | Item Package Quantity | 1 | | Batteries Required? | No | ## Images ![Battery Capacity Tester - Battery Capacity Meter Discharge Tester 18650 li-ion lithium Lead-acid 1.2-12v - Image 1](https://m.media-amazon.com/images/I/61wG6GKh-HL.jpg) ![Battery Capacity Tester - Battery Capacity Meter Discharge Tester 18650 li-ion lithium Lead-acid 1.2-12v - Image 2](https://m.media-amazon.com/images/I/61qltSXN9XL.jpg) ![Battery Capacity Tester - Battery Capacity Meter Discharge Tester 18650 li-ion lithium Lead-acid 1.2-12v - Image 3](https://m.media-amazon.com/images/I/61llahnSYbL.jpg) ![Battery Capacity Tester - Battery Capacity Meter Discharge Tester 18650 li-ion lithium Lead-acid 1.2-12v - Image 4](https://m.media-amazon.com/images/I/71YHRYINGoL.jpg) ![Battery Capacity Tester - Battery Capacity Meter Discharge Tester 18650 li-ion lithium Lead-acid 1.2-12v - Image 5](https://m.media-amazon.com/images/I/61IOYdMOg4L.jpg) --- ## 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/110689347-battery-capacity-tester-battery-capacity-meter-discharge-tester-18650-li](https://www.desertcart.tn/products/110689347-battery-capacity-tester-battery-capacity-meter-discharge-tester-18650-li) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
