Seven battery chargers in one.
Other brands require a separate battery charger for 12V charging, for AGM batteries, for 6V charging, for cold conditions, for lithium-ion batteries, and yet another for battery desulfation. With our versatile multi-purpose battery chargers, as your needs and vehicles change, your charger won't. With a simple push of a button, you'll have the power to switch between various charging modes within one, complete battery charger. And it's equipped with a progressive repair method for recovering heavily sulfated and weak 12-volt batteries. Our next generation smart battery chargers utilize the latest advancements in battery charging technology. These switch-mode battery chargers were built on a high-frequency and high-efficiency platform, which converts energy 30,000 times faster than traditional automotive battery chargers. This efficient use of electricity is what makes our chargers compact, lightweight, and incredibly portable
Safe to leave connected with zero overcharging.
Most manual, automatic or semi-automatic battery chargers continuously trickle charge batteries. Traditional chargers are susceptible to overcharge, thus limiting battery life. Our intelligent battery maintenance technology monitors battery activity, and only begins charging when needed. This system allows for continuous operation without user intervention, and zero risk of overcharging your battery
Battery maintenance made easy.
Plug-in, set and forget. It's no wonder Genius is the ultimate battery maintenance charger. Quickly connect and disconnect the battery charger when needed. It remembers the last charging mode used, and automatically resumes charging after disconnection or loss of power. The G3500 keeps any battery fully charged without supervision.
Battery charging with intelligence.
Smart battery chargers can be frustrating. It won't simply begin charging if it detects a weak or damaged battery, or force charging if it detects an unsafe or abnormal charging condition. However, prevention is just one aspect. Understanding and finding a solution is just as critical. Welcome to Advanced Diagnostics, which analyzes battery feedback and display a particular error pattern if a problem is detected. Each flash pattern tells you what's wrong, and how to quickly fix it.
Single Flash: Battery will not hold a charge and should be checked by a professional.
Double Flash: Possible battery short, and should be verified by a professional.
Triple Flash: Battery voltage is too high for the selected charge mode. Double check the battery matches the charge mode.
Error LED Solid Red: Reverse polarity. Reverse the connections to the battery.
Standby LED Solid Orange: Battery voltage is too low for the battery charger to detect the battery
