Review on 🔌 Automotive Trickle Charger - TOPDON TORNADO4000 4.0Amp for 6V 12V AGM, Deep Cycle Lithium ion Batteries - Smart Auto Charger Battery Maintainer Desulfator with Temperature Compensation by Vera Gashi

I have an old car, I don't drive much and the battery drains over time. I bought this charger to keep it charged and am very impressed so far. He reported that the battery was 50% charged when I plugged it in (see video) and fully charged it in a few hours. It also has a maintenance mode that looks like it's constantly charging a full battery, so it's perfect for my application. What I wasn't expecting is that it also has a desulphation feature that breaks down the sulphates in the battery to extend battery life - a feature I've only seen on more expensive chargers! The device itself feels very solid and well made, and the wiring and connectors are of good quality. Even the packaging gives the impression that it is a quality product. Overall I am very happy with this little charger.
