CTEK CS FREE offers a battery maintenance solution for vehicles stored with no access to a power outlet 

Batteries which are standing for an extended period will inevitably slowly discharge over time and, if left long enough, will go flat. And that’s something commonly experienced with occasional use vehicles that spend lots of time in storage or sitting on the driveway. The answer is, of course, to hook it up to a battery charger and maintainer – but what happens if you park your vehicle somewhere that doesn’t have a power outlet? 

To avoid battery woes next time you take your vehicle out for a spin, and the dreaded click of the key turning in the ignition, CTEK has launched the CS FREE. It’s a multi-functional 4-in-1 portable battery charger, smart maintainer, adaptive booster and a hi tech powerbank that can be powered up by a separate 12V service battery – perfect for longer periods of storage when you don’t have access to a power outlet. 

By connecting the CS FREE to a 12V service battery with CTEK’s USB-C CHARGE CABLE CLAMPS, you’ve got the perfect off-grid charging solution. CS FREE had dedicated maintenance charging algorithms that can keep your battery in optimum condition for long periods of time, In fact, maintenance charging your battery over any idle periods will actually extend the lifespan of your battery by up to three times . 

Gary Brown, Aftermarket Division and Product Manager at CTEK: “It’s always disappointing when your beloved occasional vehicle doesn’t start after sometimes months of waiting. By keeping batteries fully charged, even when you don’t have access to a power outlet, you can avoid a flat battery and, more importantly, a whole lot of hassle trying to get your vehicle started.”  

The award-winning CS FREE is a multi-functional, 4-in-1 portable battery charger with Adaptive Boost technology. It’s essentially four cutting edge products in one portable unit: 

Adaptive Boost: Works out the safest way to power up your flat battery to get you going within 15 minutes. 

Battery charger: Use it as a portable charger to top up your battery. You can charge the CS FREE from mains power or, if you’re off-grid, hook up to the optional solar panel kit or 12V battery for complete charging freedom anywhere you go.  

Smart maintainer: Keeps your battery in peak condition at home or off-grid.  

Hi tech powerbank: Charges up your laptops, smartphones, tablets and cameras whenever they need it. 

With CS FREE, you have the freedom to charge and maintain any 12V lead acid or lithium battery wherever you are – even if you’re nowhere near a power outlet. 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. 

CTEK’s unique range of smart chargers optimise the performance of vehicle batteries by determining accurate readings of a battery’s charge and ensuring the appropriate action is taken to optimise the battery for use, thereby prolonging a battery’s life to the benefit of both the vehicle owner and the environment. 

With each product intended for unsupervised use, foolproof to connect, spark proof and reverse-polarity protected. Available from automotive retailers and Amazon, the CS FREE comes with a 5-year warranty.
