Understanding the Technology
The CTEK MXS 3.8 uses pulse charging and desulphation technology to recover and condition deeply discharged batteries — not merely refill them. Its microprocessor-controlled algorithm adjusts voltage and current across all 8 stages, preventing the gassing and plate damage common with basic trickle chargers. This makes it equally effective as a bike battery trickle charger or a full car battery maintainer for vehicles like the Kia Seltos with AGM batteries.
