Don't be afraid your charger will not be powerfull enough.
I have only one charger in my garage: a small Optimate, 5 years old, for motorcycles. Works perfect on car batteries. Only one disadvantage: it takes a bit longer to charge a car battery. But that doesn't bother me. No matter what charger, the next morning your battery is fine.
What's nice about the Optimate: it is very, very gentle for your batteries and stops charging when full. It will automatically restart if you keep the thing connected (motorcycle in wintersleep e.g.) and the batterievoltage drops under a certain tension.
No experience with Ctek.
