How do I find out what it means?** A: A full explanation of error codes and possible solutions is available in the user manual. You can also contact Schumacher Electric for assistance. **Q: Why is there is a clicking noise coming from the charger?** A: The clicking noise indicates that the circuit breaker is cycling, the connected battery is defective, the battery clamps have shorted, or the battery is severely discharged, but otherwise in good condition. Check the user manual for more information. **Q: Why is the display showing “SUL”?** A: This indicates that the battery is sulfated. The charger will automatically attempt to repair the battery. If the battery has not resumed normal charging after 10 hours, have it checked. **Q: Why won’t the engine start work?** A: There are several possible reasons, including that the vehicle is drawing more current than the engine start rate, failure to wait 3 minutes between cranks, the charger is overheated, or the battery is severely discharged. Check the user manual. **Q: The charger is making a loud buzz. Is this normal?** A: The buzzing sound results when the transformer laminations vibrate. This is normal and there is no cause for concern. ## Frequently Bought Together - Schumacher Electric DSR122 ProSeries Fully Automatic Car Battery Charger - 125/275 Cranking Amps - 6v / 12v Battery Charger - Fully Automatic Battery Maintainer + Engine Starter - Amazon Basics 48-Pack AA Alkaline High-Performance Batteries, 1.5 Volt, 10-Year Shelf Life - Schumacher Electric DSR159 - ProSeries Jump Starter - 12V 4000 Peak Amps Portable Car Jump Starter & Maintainer - Jumper Cables with Battery Pack - 700 Cranking Amps --- ## 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.co.th/products/89762262-dsr-pro-series-6v-12v-battery-charger-and-engine-starter](https://www.desertcart.co.th/products/89762262-dsr-pro-series-6v-12v-battery-charger-and-engine-starter) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-29*
