Review on 🔋 MAGLONG Smart Automatic Battery Charger with LCD Display - 6V/12V 1-4A - Automotive Battery Maintenance Charger for Car, Motorcycle, Lawn Mower, Boat, RV, SUV, and ATV - Waterproof and Eco-Friendly by William Mathis

This is definitely a cool smart charger. It was recommended to me by my brother-in-law. I wasn't sure if this would work or not, but I decided to give it a try. And gave him a car battery that I knew was bad. It started on the 15.XV and gradually returned to the 6.XV and soon a bad battery notification appeared. Then tried it with a running battery for a test, it showed charging first and then went back to a full charge within an hour or so. This little screen shows a whole lot of different information. In general, I liked it, let's hope that I will not need it in the future. :)
