Great way to check on the viability of car/ boat batteries. Worth every penny! ### ⭐⭐⭐⭐⭐ nice tester *by P***M on December 8, 2025* works great ### ⭐⭐⭐⭐ Good, cheap *by A***S on April 15, 2026* Cheap and works for what I need it to. Mostly testing 6v deep cycle batteries for electrical pallet jacks. If you want accurate voltage readings, you'll need to use a multimeter as well, the analog dial isn't very easy to get exact numbers from. Haven't tested on a 12v. On a 6v it pretty consistently draws 48-50 amps, which is true to its 100amp rating at 12v ## Frequently Bought Together - NEIKO 40510A Car Battery Tester | 100 AMP 6 and 12 Volt Automotive Load Checker | CCA Analyzer - EZRED SP101 Battery Hydrometer, Factory - FORTIVO Battery Restorer and Desulfator for Lead Acid Battery - Prolong Life & Boost Charge Capacity, Battery Acid Refill and Additive for Golf Cart, RVs, Bikes, ATVs, Car Battery 64oz --- ## 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.hr/products/62695548-40510a-car-battery-tester-100-amp-6-and-12-volt](https://www.desertcart.hr/products/62695548-40510a-car-battery-tester-100-amp-6-and-12-volt) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-15*
