Great way to check on the viability of car/ boat batteries. Worth every penny! ### ⭐⭐⭐⭐⭐ Ahhh it works *by on Reviewed in the United States March 20, 2023* Make sure you read the book it says it'll get hot enough to burn you and cause property damage that it can it says it will get hot enough and will burn you. It worked a couple seconds used it to test one battery. As soon as you hook up the cables instantly goes to where it should be so you can unhook it then if that's all you wanted to do then with the load tester you know hook up the cables and instantly reads and then hit the load tester maybe two seconds and it goes right to where it should there's no need to run it any longer than 2 seconds then unhook it. Used it a few I like it. It does get warm fast probably hot like booklet says if you hold the load tester mire than a few seconds. It did smoke till the 5th use now no smoke. Cheap price no big name brand but it works great. ### ⭐⭐⭐⭐⭐ This is the best of the knockoff battery testers hands down *by on Reviewed in the United States October 19, 2023* I decided to get a battery tester to keep up with all the various 12 volt batteries we use on our farm. I didn't want to spend 50 bucks for the name brand so looked at all the different knockoffs and settled with this Neiko. I can now say I made the right choice! I have tested it on about a different different batteries and it does exactly what it was designed to do. It shows how much voltage sag happens when batteries get put under a load. It clearly showed me which batteries are getting weak and which ones were still strong. The tester is well built and well designed. It should last for years. Nice when something is cheap and works good. This one is a winner! ## 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.tn/products/62695548-40510a-car-battery-tester-100-amp-6-and-12-volt](https://www.desertcart.tn/products/62695548-40510a-car-battery-tester-100-amp-6-and-12-volt) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-19*
