CTEK LITHIUM US – Advanced 12V LiFePO₄ Battery Charger (4.3 A)
The CTEK LITHIUM US is a high-performance microprocessor-controlled battery charger designed specifically for Lithium-Iron Phosphate (LiFePO₄) batteries. Delivering up to 4.3 amps of charging power, it ensures optimal charging, reconditioning, and long-term maintenance for batteries ranging from 5Ah to 60Ah (maintenance up to 120Ah).
With CTEK’s 8-step ‘connect-and-forget’ charging program, the LITHIUM US automatically analyzes battery condition, restores capacity, and provides patented float/pulse maintenance to preserve long-term health. It’s engineered to safely reset low-voltage protection electronics without disconnecting the battery, making it ideal for vehicles, powersports, and marine applications.
Designed for durability and reliability, the LITHIUM US is spark-free, reverse-polarity protected, and IP65-rated for resistance against dust and water.
