Hooked up to battery, got a voltage reading, started the car but it doesn't show anything on the alternator side** A: Leave the tester on the battery, it should read at least 12v, start your car, if the reading didn't go up for at least 14v, you're alternator is not working.... **Q: What is the Cigarette lighter adapter for?** A: to test the battery through the cigarette lighter of the car instead of raising the hood and clamping on the battery. **Q: Will this also work on a 12v marine battery?** A: Absolutely. It should register around 12.0-12.6 volts when the vehicle it turned off. If it registers a little higher when the vehicle is running, then that means your alternator is working perfectly fine. It’s a great tool to have. It’s good to check your battery every once in a while. It’s worth the money. **Q: Can this tester be used with three batteries wired in parallel?** A: If the battery voltage in parallel or series exceeds 3V, it can be measured ## Customer Reviews ### ⭐⭐⭐⭐⭐ Small but mighty *by H***S on December 24, 2025* It's small but works like a big tester can carry it in you pocket ### ⭐⭐⭐⭐⭐ Easy to read, easy to use *by C***4 on January 14, 2024* This seems to work very well. It gives me an immediate reading of the battery charge & the alternator's output. I like the versatility of having alligator clips AND the 12v DC cigarette lighter plug adapter. I may buy a 2nd so I can keep one in the Class B RV Van? ### ⭐⭐⭐⭐ It's really nothing more than a glorified voltage tester, to be honest *by G***K on April 6, 2023* When I bought this device I was expecting it would have some kind of diagnostic capability to assess the battery and the alternator. It doesn't. There are 3 positions: 24v, alternator, and 12v. But these positions don't do anything more than simply shift the scale on LED readings. In fact, the alternator position isn't really useful... because you get the same reading for the battery when the engine is running--it's showing the charge received from the alternator. The panel shows a series of LED's to let you know the "analysis" of the battery health. But there is no complex diagnosis happening. Based on the voltage detected, a corresponding LED will light up for the predetermined range of what is established for Full, Medium, Low, and Empty. You could simply refer to a static chart for battery voltages: 12.7 = 100% 12.5 = 90% --------------- ^ Excellent 12.4 = 80% 12.3 = 70% 12.2 = 60% --------------- ^ Good 12.05 = 50% 11.9 = 40% --------------- ^ Low to Fair 11.8 = 30% 11.6 = 20% --------------- ^ VERY low (may not start) 11.4 = 15% 11.3 = 10% --------------- ^ DANGEROUSLY low (likely won't start) DEAD If you don't have a multimeter, this device is handy. The best testing is ALWAYS directly from the battery terminals. If you do it from the cigarette lighter, you will get a lower reading because of the circuitry (potentially off by as much as 0.5v). PLUS: You are given 2 connectors to test the battery. The clips are the best way. However, one nice touch is the coupler used. This is compatible with some adapters that are used with car chargers such as ADPOW. I use an ADPOW charger for my battery periodically (since I don't drive a lot) and installed the adapter for a quick, easy, and safe way to connect the charger. This AUTDER tester uses the same plug, so I don't need to mess with the clips. My multimeter is a Fluke 73. It's extremely accurate. This tester runs a little low in comparison, by 0.05 to 0.1v. I don't know if the maker does any kind of calibration... so maybe other units could show different deviations. I would, as a measure for peace of mind, compare your tester to a professional multimeter to be sure it's within an acceptable range. I'm not happy my AUTDER tester doesn't match 100%, but it's close enough and at least underreporting. CONS: For the price, I guess it's not a bad deal but the word "analyzer" is rather misleading. This is a tester. It doesn't do any notable diagnosis that you couldn't determine yourself by looking at a voltage chart. The clips for attaching to a battery terminal are rather cheap, thin, easily bent, and the insulator sleeves are not well secured. The directions do not warn of lower than actual voltage readings from the cigarette lighter. Also my example showed a slightly lower than actual reading compared to a multimeter. There is no included storage case. PROS: For those people completely ignorant about what voltage levels equate to full, medium, low, and dead, this device is helpful. It's good that there's 2 ways to test this--battery terminals or cigarette lighter (but beware the latter will show as lower than actual). It's also great that a standard connector is used instead of proprietary, so if you've got a wired adapter already connected to your battery you can use this tester directly. The LEDs are reasonably bright. Also, the unit is not very heavy. ## Frequently Bought Together - AUTDER Car Battery Tester and Alternator Tester 12V/24V with LCD Display and LED Indication Automotive Battery Voltage Meter for Cars Trucks Motorcycles - YONHAN Battery Charger 10-Amp 12V and 24V Fully-Automatic Smart Car Battery Charger, Battery Maintainer Trickle Charger, and Battery Desulfator with Temperature Compensation - NOCO GENIUS1, 1A Smart Car Battery Charger, 6V and 12V Automotive Charger, Battery Maintainer, Trickle Charger, Float Charger and Desulfator for Motorcycle, ATV, Lithium and Deep Cycle Batteries --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/276097252-autder-car-battery-tester-and-alternator-tester-12v-24v-lcd](https://www.desertcart.com.kw/products/276097252-autder-car-battery-tester-and-alternator-tester-12v-24v-lcd) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-19*
