The LITHIUM US is an advanced microprocessor controlled charger specially designed to recharge and maintain the cells of Lithium-Iron (LiFePO4) batteries - maximizing their performance and lifespan. With up to 4.3A of charge current available the LITHIUM US is extremely flexible and will charge LiFePO4 batteries from 5Ah to 60Ah and maintain up to 120Ah.
With up to 4.3A of charge current available, the LITHIUM US can charge LiFePO4 batteries from 5Ah to 60Ah and maintain up to 120Ah. It’s easy to use – just connect it and charging starts immediately. There’s no need to disconnect your battery and any low voltage protection electronics will be reset automatically. The LITHIUM US is a ‘connect and forget’ charger with 8 charging steps, a testing sequence that tells you if the battery can take and retain the charge, a unique maximization step to restore full capacity and patented maintenance charging for maximum performance, even after months of inactivity.

*) Back current drain is the current that drains the battery if the charger is not connected to the power outlet. CTEK chargers have a very low back current.
**) The quality of the charging voltage and charging current is very important. A high current ripple heats up the battery which has an aging effect on the positive electrode. High voltage ripple could harm other equipment that is connected to the battery. CTEK battery chargers produce very clean voltage and current with low ripple.
