From the manufacturer

Battery Charging With Intelligence

GX Series Chargers begin charging upon detecting a weak or damaged battery and never force charge upon detecting an unsafe or abnormal charging condition. Prevention is key. However, understanding and finding a solution is just as critical. Advanced Diagnostics analyzes battery feedback and displays a particular error pattern if a problem is detected. Each LED flash pattern tells you what's wrong, and how to quickly fix it. For example, LED flash patterns will tell you if the battery will hold a charge if the battery might be shorted, and if the voltage is too high for the charge mode or too low to be detected.

GX4820 48V 20A Ultra Safe Industrial Battery Charger

92% Efficiency

With over 960-watts of pure power, the GX Series uses incredible thermodynamics to deliver the most compact, yet powerful industrial battery charger ever. Rather than only using heat sinks, its precision aluminum unibody maximizes not only airflow but also thermal capacity.

Repair Mode

Repair Mode is an advanced battery recovery tool used to remove sulfated batteries, and regain lost battery capacity. It uses a combination of high voltage and low current to melt down sulfation and return it to the active material again.

Supply Mode

Supply Mode converts the industrial battery charger into a constant current, constant voltage power supply for zero voltage charging for troubleshooting low voltage batteries or equalizing unbalanced battery system for longer battery life.

Ingress Protection

Industrial battery charger applications are exposed to some of the toughest and most extreme operating environments. Whether an onboard or offboard application, these chargers are shock, vibration, water, dirt, and dust proof and rated at IP66.
