It read 12.4 volts . This was way easier than using a multi meter. Also used on two 12 v deep cell batteries that didn't seam to charge. It confirmed they weren't changing. This is a great tool at a bargain price. Would buy again.👍👍 ### ⭐⭐⭐⭐⭐ Great item *by K***N on August 2, 2024* Great addition to my toolbox. It takes the guess work out of troubleshooting a 12VDC system. The coiled cord helps. ### ⭐⭐⭐⭐⭐ Feels heavy duty *by D***G on January 19, 2024* Works great. --- ## 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.vu/products/541347123-zkfar-pack-1-automotive-test-light-digital-led-circuit-tester](https://www.desertcart.vu/products/541347123-zkfar-pack-1-automotive-test-light-digital-led-circuit-tester) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-02*
