CTEK CS FREE - Frequently Asked Questions

The CS FREE will charge all types of 12 volt lead-acid batteries, and Lithium-Iron-Phosphate (LiFePO4) Sized 10-130 ah.

No, that is not necessary.  The CS free will charge all types of lead-acid and Lithium iron phosphate batteries.  Simply press the ON/OFF button and the charger will take care of the rest.

CS FREE will charge lead-acid as well as Lithium (LiFeP04) with the same charging algorithm.  The charge curve has been specially developed to charge both chemistries in a safe and effective way.

The standard approach is to connect the positive clamp to the positive battery terminal or charging point and the negative clamp to the negative battery terminal, earth or ground point on the vehicle chassis, or recommended charge points. PLEASE NOTE: You should however, always follow vehicle manufacturer recommendations on how to charge your battery. These can be found in your vehicle manual.

Yes, but keep it apart from hot surfaces and sharp edges and ensure there is room for the charger and the cable. NOTE Do not drive your car with the CS FREE under the bonnet.

Yes, we recommend that the charger is connected and switched on when you attempt to start the vehicle. Please make sure all consumers (Fan, headlights, wipers etc.) is turned off during the start attempt.

Yes, as with all CTEK chargers, it is recommended to be left connected and switched on when cranking attempt is made.

Not connected to mains or other power source, you can charge as long as the internal battery has got any power left (indicated by the smaller display on the charger). How long that will last, depends on how discharged your battery is.  When connected to a power source, you can use it as a regular battery charger & maintainer, for charging and for short- or long time maintenance.

The CS FREE will start automatically when it is connected to any input sources. If the CS FREE is used without any input, you need to press to ON/OFF button. On top of the charger there is two circles of lights, the smaller one is also the ON/OFF button.

No it does not show SoC of the battery. The MMI features a countdown display that shows you how long there is left to go until the battery is fully charged. Once the battery is fully charged the MMI will slowly pulse all six segments synchronously.

No, the CS FREE is too powerful for standard CTEK connectors. The CS FREE will charge with up to 20A, and the standard CTEK connectors can only handle up to 10A.

That depends on how much electronic components are active when parked, and the battery state of health, and that will be very individual from case to case. For normal car/battery we recommend you to recharge your CS FREE approximately once a week for best battery maintenance.

When connected to a power source, you can use it as a regular CTEK charger, for charging and for short- or long-time maintenance.

CTEK's new CS FREE can be used without main power connected.

Yes, the CS FREE is a portable charger, that you can bring with you and charge wherever you are, no matter if there are mains available or not.

CTEK's new CS FREE is a completely portable battery charger and maintainer that can be used without mains power, so you really can use it any time, any place, anywhere!

The physical size is 248mm x 98mm x 78mm, and it weighs 1.4 kg, and there is also a smart bag as an accessory, so you easily carry the charger and the accessories with you.

We recommend that the CS FREE is only used with the CS FREE SOLAR PANEL KIT, specially developed to work with the CS FREE, for maximum performance and efficiency.

THE CS SOLAR PANEL KIT features a 60W panel. We recommend that the CS FREE is only used with the CS FREE SOLAR PANEK KIT, specially developed to work with the CS FREE, for maximum performance and efficiency.

The CS FREE can handle inputs of up to 25V from the CS FREE SOLAR PANEL KIT, higher voltages risk damaging the CS FREE unit. To protect against this, we recommend that the CS FREE is only used with the CS FREE SOLAR PANEL KIT, specially developed to work with the CS FREE, for maximum performance and efficiency.

The MPPT is within the CS FREE, and it works together with the safety box fitted on the cable to the solar panel charge kit. The safety box makes sure the voltage is within the range of what the CS FREE can take. For this reason, we only recommend you to use the Solar panel charge kit together with the CS FREE.

If the charger has no input and no output for 10 minutes it will automatically power off.

IP rating is 54.  Dust and flush safe. This means that dust in harmful amounts cannot get into electrical components so that insulation faults can occur. The luminaire must be tight, and gaskets are therefore necessary. Tested in a dust chamber. IPx5 requires flushing resistance (not high-pressure flushing). So, use the charger outside! In rain and fog the charger itself is built with a "heel" so even if it stands in some mm of water, it will work fine.

CS FREE is an Adaptive Booster, it will talk to the battery to see how much charge it needs to get the vehicle started within 15 minutes, and it is safe for the battery and the electronics in the car.

The CS Free will only detect a battery if the voltage is over 3 volts, and it will also choose not to charge if the voltage is over 14 volts.

3 volts is an extremely discharged battery, this is what makes the charger reverse polarity protected and short circuit proof.

If you have any power connected to the charger it will charge up to 5A. If you do not have any power connected to the charger, it will charge up to 20A as long   as there is power left in the internal battery of the CS FREE.

No, there are no selectable charge modes, it is fully automatic. If you need the SUPPLY function I recommend you to use another CTEK charger.

The CS FREE does not have a wake-up function. If the LiFePO4 battery has closed down, you have to use another power source to wake it up.

15 minutes is the time it can take to empty the internal battery, if the receiving battery is empty. Most cars are ready to start within 15 minutes, if it does not, please recharge the CS FREE and try again. If the car still does not start it would be a good idea to get the battery tested it might be in poor condition and needs to be replaced.

It can be charged in different ways. You can charge from mains with the PD adaptor supplied in the box, or with additional accessories (not supplied) through a 12V output in the car (USB-C CHARGE CABLE 12V PLUG), from another battery with battery clamps (USB-C CHARGE CABLE CLAMPS) or from the CTEK SOLAR PANEL CHARGE KIT.

From "Less than 10% left" - (first led blinking) to fully charged, it will take up to 60 minutes, as long as CTEK standard accessories are used.

It is a Lithium Polymer-battery.

Yes, you need to have the additional USB-C CHARGE CABLE 12V PLUG. It will start charging as soon the motor is running.

Yes you can! The internal battery will not get overcharged so when fully charged, it will stop charging even if the input is still active.

The lifespan is 300 charges cycles with a remaining capacity of 80% or more. Warranty time for CS FREE is 2 year.

The lights in the big circle on the top of the charger light up, and one of the LED's is blinking, this tells you that the charger is charging.

When the first LED "START" is lit with a steady light, the vehicle will most likely have power enough to start.

All LED's in the bigger circle are lit and the lights are slowly pulsing, the battery is fully charged.

Yes, like all CTEK chargers it can be connected for long periods of time. Please note that if the CS FREE is not connected to an external power source, the charger will only work as long as there is power left in the internal battery.
