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 ### ⭐⭐⭐⭐⭐ Good piece of kit *by A***. on 15 January 2024* Seems to give accurate enough of a reading, used it to check tractor battery and alternator, showed battery to be low in charge and alternator not sending a charge which was the case so I installed a new alternator which solved the problem, it gives a good clear readout off the power it's receiving from the battery it doesn't need its own battery, all in all I'd say it's a good piece of kit, its well made fairly accurate and cheap, worh having to keep a check on your battery or alternator, it works on any 12volt system would recommend came on time well packaged and my fixer guy was impressed by it's ability too. ### ⭐⭐⭐⭐⭐ Excellent piece of kit *by P***H on 22 January 2022* My motorhome has been standing idle over the last few months and I wanted an indication of the battery output and the alternator output.

Arrived on time, well packed and in good condition ### ⭐⭐⭐⭐ Good Little Unit *by R***E on 13 January 2026* The plug connector option is handy, but check whether your car only powers the sockets when the engine is running (in which case you will have to use the clips to measure the battery when not being charged). Build quality of unit appears to be good and simple to use with "traffic lights" indicators. ## 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? - 🛒 **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.jp/products/313914941-autder-car-battery-tester-12v-24v-voltmeter-for-car-motorbike](https://www.desertcart.jp/products/313914941-autder-car-battery-tester-12v-24v-voltmeter-for-car-motorbike) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-14*
