Review on 🔌 Schumacher 10 Amp/3 Amp Fully Automatic Battery Charger, Maintainer, and Auto Desulfator - 6V/12V - Ideal for Cars, Trucks, SUVs, RV Batteries by Matt Schmick

Chargers need to top up a discharged battery with enough energy to not exceed the battery's capacity to accept a charge, so there are several charge rates to choose from. The charger also recognizes when the battery and charger are exhausted. correctly connected. Also, the charger will not charge a fully discharged battery. This can lead to a dangerous situation or an explosion. Also, the charger must be safe so that if the user is negligent, the charger will not lead to an unsafe condition. Finally, the charger must accommodate batteries of different types, such as sealed or maintenance-free, AGM and deep cycle batteries. Each of these battery types is charged differently to optimize performance and battery life. So a good charger should be smart enough to provide the right charging profile for whatever battery you connect it to. A good charger should be able to detect a sulfated battery and recover the battery with a special desulfation mode. Keep this in mind when using this charger; First connect the battery poles, paying attention to the correct polarity (color). Then plug the charger into a 120V AC outlet and select the charging voltage and speed. This is a safe way to use this charger and the charger will start a diagnostic cycle to determine if the battery needs to be desulphated. Battery, two car batteries and four 6 volt deep cycle RV batteries wired in series and parallel. I also loaded two 12v chassis engine starter batteries connected in parallel (these batteries give about 1200 CCA to start a CAT diesel engine). It takes some time for the battery to be fully charged. Be patient. The charger repairs the battery and recharges it at the same time. You're talking about a 50 pound piece of lead and plastic (battery) that costs $75 to $100 to replace and that needs to be filled with electrons before it fully recovers from your charge. At sight. It may take 24 hours to fully repair and charge. For less than $35, this charger does it all and turns off when the battery is fully charged and automatically enters maintenance mode, allowing the user to leave the charger plugged in indefinitely. This is a bargain and comes with a 5 year guarantee.
