Specially adapted for extreme charging between -22


The one-of-a-kind CTEK 4.3 Polar provides modern, advanced technology alongside a special adaptation to handle severe cold down to -22°F (-30°C). It was developed for vehicles requiring good battery care during cold winter periods, such as snowmobiles, ATVs, jeeps and cars. The CTEK Polar has a modified charging voltage function for optimized charging in extremely cold temperatures for both small (snowmobiles and ATVs) and normal-size batteries (jeeps and cars). The charger also features a unique reconditioning function which is capable of restoring stratified and deeply discharged batteries. CTEK POLAR is equipped with extremely cold-resistant rubber cables on both sides (AC and DC to the battery). With the advanced 8-step charging system, the charger analyses whether the battery can receive and maintain a charge. It is completely automatic and switches to effective maintenance charging when the battery is fully charged
