Life is great – and even more so when you can freely manage your time. When you think of the freedom and joy that driving a vehicle offers, you probably don't first think about charging the battery. In fact, charging the battery is the simplest and most time-saving way to maintain your vehicle. With the unique CTEK feature Time To Go, you can monitor the charging process and better plan your time, as the remaining charging duration is accurately predicted. Based on Swedish technology, the CT5 Time To Go provides maximum battery performance for all 12V vehicle batteries. You can ensure that your battery is always in perfect condition – even in winter, and you can even repair a deeply discharged battery that hasn't been charged for too long. The CT5 Time To Go is easy to use and operates fully automatically – the electronics analyze the condition of the battery and then select the optimal charging or maintenance mode by themselves. The CT5 Time To Go is currently the only charger on the market that shows you the remaining charging time for the battery. The individual charging phases and the remaining charging time until the battery is fully charged are displayed via a series of LEDs. There is also an LED that indicates when a safe attempt to start your vehicle is possible, i.e., when the battery is ready for driving. For your peace of mind: it is absolutely safe to use the CT5 Time To Go continuously.
