CTEK Polar is a one-of-a-kind charger with its modern, advanced technology and its special adaptation to handle severe cold. It was developed for vehicles requiring good battery care during cold winter periods, such as snowmobiles, ATVs, jeeps and cars. CTEK Polar has a modified charging voltage function for optimised charging in extremely cold temperatures. The function is available for both small (snowmobiles and ATVs) and normal-size batteries (jeeps and cars). Another unique quality is that the reconditioning function (which restores stratified and deeply discharged batteries) is available for both the small and normal-size 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 – a huge benefit in the cold. CTEK POLAR works well in regular climates, but is adapted for charging between -30°C and +50°C.
