Review on 🔋 Smart 10-Amp Car Battery Charger: Fully Automatic 12V and 24V Trickle Charger with Temperature Compensation for Car, Truck, Motorcycle, Lawn Mower, Boat, and Marine Lead Acid Batteries by Nathan Issa

Despite some bad reviews, it's obvious that many people lack the common sense to use a charger. He does what he claims. If your battery is completely dead and this charger doesn't recognize it, just plug in a regular old fashioned charger and let it charge for a bit, then upgrade this charger and it will recognize it and work just fine. For people who complain about poor instructions, it's a basic charger with a 120-volt plug that fits into a standard household outlet, a red and black clip that connects to the battery, and a simple push-button switch to turn to choose between the battery types.
