Winter charging

BE WINTER SMART. CHARGE YOUR BATTERY. KEEP MOVING.

Sub zero temperatures can have a serious impact on your battery’s efficiency, which could make your vehicle difficult to start.

Your battery is working much harder in cold weather, but your alternator might only be charging it up to around 60% of its capacity. This could mean your engine is using up to 5-10 additional horsepower and burning more fuel.

So not only is your battery underperforming, but it could also lead to an expensive breakdown.

Making sure your battery is fully charged and maintained with a reliable, efficient charger is essential in extremely cold temperatures. That’s why CTEK designs easy to use battery chargers that will keep you moving, whatever the temperature dial says.

CTEK CS FREE

Portable winter charging with Adaptive Boost

CS FREE is the world’s first 4-in-1 portable battery charger, maintainer and hi-tech powerbank which features CTEK’s revolutionary Adaptive Boost technology.

Adaptive Boost gets you back on the road quickly if your battery dies in cold weather and you’re nowhere near a power outlet. It works by analysing the battery and automatically working out the safest way to power it back up and get your vehicle started again within just 15 minutes.

And unlike most ‘boosters’, CS FREE is sensitive and safe, so it avoids damaging your battery or your vehicle’s electronics by only giving it the charge it needs to get you going again.

CS FREE is also a fast, efficient battery charger and maintainer that works in temperatures as low as -20˚C (-4˚F) with mains power, solar power or hooked up to a 12V leisure battery.

Countdown to winter smart charging

CTEK’s CT5 TIME TO GO’s easy to read timer display shows you exactly how long there is to go before your battery is fully charged, so you don’t have to wait around in the cold.

It’ll also tell you when you have enough charge to safely start your vehicle and get you going again quickly on crisp, winter days. CT5 TIME TO GO has automatic built-in temperature control, which means it’ll do all of this in conditions as low as -20˚C (-4˚F).

It’s easy to use, too – just connect it, power it up and select either the ‘normal’ 12V or AGM battery mode, then simply leave it to do the rest.

CT5 TIME TO GO uses tried and tested CTEK technology to make sure your vehicle starts every time and your battery is in peak condition, even in freezing weather.
