The CTEK Lithium XS 12V battery charger and maintainer is an advanced microprocessor-controlled device, specially designed for the proper charging, maintenance, and longevity of lithium batteries. 

It is fully optimized for lithium iron phosphate technology batteries (12V LiFePO4) and is ideal for capacities from 5Ah up to 60Ah.

Advanced 8-Stage Charging & Diagnosis
CTEK stands out because it uses a smart 8-stage charging algorithm. At each stage of this automatic process, the device continuously monitors and evaluates the condition of your battery. 

In this way, it precisely adjusts the current intensity to achieve the maximum possible energy storage without stressing the cells, making it ideal for both fast charging and long-term maintenance during winter storage.

Low Voltage Reset & Absolute Safety

Lithium batteries have an internal management system (BMS) that "locks" and cuts off power if the voltage falls below a certain limit. The Lithium XS solves this problem thanks to a special reset button, which sends a signal to "wake up" the battery's BMS and start charging normally. 

Additionally, it features full short-circuit protection, preventing sparks or damage to the vehicle's electronic systems in case of incorrect terminal connection.
