CTEK in the Cold

In the past, charging a battery in the cold was a losing battle, but CTEK has changed that. The SNOWFLAKE mode and the MUS 4.3 POLAR are specifically designed to charge your battery in cold conditions. And, you don't lose any of the performance that other CTEK smartchargers supply.

The MUS 4.3 POLAR is made for cold weather, with adapted AC and DC cables that can handle the cold weather down to -22F (-30C). The "snowflake" mode makes sure that the charging process runs ideally even in extremely cold conditions. There's no good time for a dead battery, but in the middle of a cold spell tops the list. The MUS 4.3 POLAR provides superb charging with added winter performance.

Although the MUS 4.3 POLAR is designed for the cold, it provides top of the line charging all year round. Using an advanced microprocessor, the smartcharger can handle batteries from 1.2Ah up to 110Ah. So whether you are charging your snowmobile, 4X4, or snowplow, the MUS 4.3 POLAR can tackle the task.

New Charger, New Technology

Remember when you had to lug a heavy charger to your vehicle, make sure you attached it correctly, and then tried to decipher what the dials, buttons, and gauges all meant? The MUS 4.3 POLAR does away with all of that. Weighing just over one pound, the smartcharger does the work of chargers weighing 5 times as much. It's impossible to attach the charger wrong and cause damage. The system is spark-free and if you put the connectors on wrong, it won't do anything until you reattach them correctly. Once the smartercharger is connected, your work is done until it's time to remove it. The entire charging process is automatic and is easily followed on the LED display.

The fully automatic smartcharger has eight charging steps that allows you to keep your battery charged and maintained. The process not only keeps your vehicle ready to go, but it also extends the life of your battery, saving you money, time, and effort.

Don't let the cold weather keep you from using your favorite vehicles. The MUS 4.3 POLAR may be just the solution you are looking for to keep your battery charged and ready to go all winter


“Having owned several of another ‘popular’ brand of charger, the CTEK is far and above superior in every possible category. WELL worth the miniscule additional cost. ”
