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 Juan Wilson

The charger stops charging when the battery is fully charged and does not keep the battery charged. It must be disconnected and reconnected to start charging again, even if the battery voltage has dropped sharply. Hits the charger's target. As if that wasn't enough, until after 2 months it completely failed - no longer lights up or charges. Totally dead. This is currently outside of Revain's return policy and there is no obvious manufacturer website to contact them directly for a replacement. All in all, you save your money on this item and get a more established and trusted brand.
