Kind of like plugging a toaster onto your battery. It will draw a lot of juice off the battery in just one test with smaller batteries so if they are weak you will know it fast and they will likely need a recharge afterward. I use it for 4 and 8 D size batteries for starting large diesel engines. I would suggest a lighter amp load tester for what you are doing. Something around a 50 amp range.Hope this helps.Paulpaulmgriswold@aol.com **Q: So this would tell you if a car battery is working properly Etc?** A: It puts a load,like you're trying to start your car,on the battery, and will tell you if the battery is bad. Most batteries last 5 to 6 years cheaper ones less so if it's old just buy a new one But if it's newer you might want to check it before buying a new one. The battery has to be charged though, you cannot check a dead battery , so unless you have access to a battery charger this won't help you. **Q: will this work on 8 volt golf cart batteries?** A: Hi Cabo, It might as it has scales for 6 or 12 volt. It would read a little high on the 6 volt scale when checking 8 volt. I can't promise it will work though. ## Frequently Bought Together - OTC 3181 130 Amp Heavy-Duty Battery Load Tester Black - Clore Automotive Jump-N-Carry JNC660 1700 Peak Amp 12 Volt Jump Starter , Blue --- ## 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.fr/products/287076880-otc-3181-130-amp-heavy-duty-battery-load-tester](https://www.desertcart.fr/products/287076880-otc-3181-130-amp-heavy-duty-battery-load-tester) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-10-29*
