The product is great, unique and high quality, solving my problem. The manual however is a terrible picto puzzle. In many reviews buyers complain about this. Add some english text and 90% of the world will understand it better. Now it is total bs.
Firstly, I swear by your product! Really saved my skin on several occasions since buying it. Anyway, another question - I see the CS Free is good for 300 cycles before it drops to "over 80%" charge. If I'm using a deep cycle battery, is this number still relevant or will the life of the CS Free be extended because it's using the deep cycle battery instead of the internal battery?
Okay your pitch has got me. Gonna buy this but goodness me £80+ extra for the carry case and who knows how much for the 12v socket accessory to be able charge it back up while driving car via cigarette lighter socket. Surely cost of this could include a protective case as standard!
I own 3 different CTEK chargers for different applications and I love them. My question is: Will the CS Free able to start a VW 2.0 diesel engine after the battery is dead? Thanks!
Hi. Thank you for choosing CTEK over and over. If the battery is just too drained to start the car, a fully charged CS FREE should be able to get it started within 15 minutes. If you have the possibility to charge before it gets so drained that it will not start the car - that would be so much better for the battery. Good Luck. Best regards CTEK Support
@@CTEKBatteryChargers As you know, your video doesn't say if there is a certain percent of existing charge that the battery must have in it in order for the adaptive boost feature to be able to start the vehicle. What is the minimum percent of existing charge that must be in the battery, in order for the adaptive boost feature to start the vehicle? If the existing battery charge is below that minimum percent, does the CS Free state the percent of existing charge, such as zero or 1 percent?
CTEK Thanks for creating great products! Can the CS Free be used via adapters to maintain the battery via the eyelet connectors? I have RAV4 Hybrid where the battery is at the back of the car and I don't want to leave the CS Free under the car hood and also don't want to take apart the back of the car each time I connect the CS Free
Hi. Thank you for your kind words. You can not use the CS FREE together with the connector and indicator products. The reason is that those products are made for currents up to 10A and the CS FREE will, when used without power into the charger, charge with up to 20A. That high current risk damaging and shortcut the thin cables in the accessories. Kindly use the provided clamps for best result. Best regards CTEK support

Hi Johan. I',m going to purchase the CS FREE for my BMW R 1150 GS motorcycle, connecting it - mainly in charge mode because I don't go out with the bike so frequently (so maintaining the battery charge) - NOT directly to the battery terminals pf my motorcycle BUT to the on-board electrical socket. Which kind of connector /adapter should I buy ? I've heard in your video that the duration of the CS FREE (full charged) for a battery maintenance could be a couple of days, do you confirm ? Thanks and many compliments for your video !
Hi! Because of its high power output, the CS FREE can only charge through its supplied clamps and is not compatible with other CTEK adaptors. If you have access to a power outlet where you store your motorcycle, I would suggest to get another CTEK charger, such as the MXS 5.0, CT5 POWERSPORT or CS ONE (together with the CS CONNECT ADAPTER CABLE).

Hej kan man ladda upp sin egen bil utan elkabel insatt i väggen,och går det först ladda upp Ctek och sedan ladda batteriet i bilen utan eluttag inkopplad i själva ctek och hur länge kan man ladda ett halvdåligt batteri?
Hej! Du kan ladda ditt bilbatteri med CS FREE utan någon extern strömkälla men laddaren kommer få slut på ström i det interna batteriet relativt snabbt. Om du vill använda CS FREE som en batteriladdare (snarare än en Adaptiv Booster) rekommenderar vi att använda en extern strömkälla, så som ett eluttag, ett externt batteri eller en solpanel. Om du inte har den möjligheten så kan du som sagt ladda upp CS FREE och sedan ladda bilbatteriet, men beroende på hur urladdat det är kan det krävas att du gör detta ett flertal gånger.
If you car gives you a warning for low battery, can you use the CS Free to charge it to full by successive charging in battery mode? It seems to me that you can only get the battery energy high enough to start the car? What are the acceptable voltage levels on the USB input?
Hi! When using the CS FREE completely portably you have an Adaptive Booster that gets you going from a flat battery in a safe way. But the CS FREE is also a regular battery charger that you can use for long-term charging when plugged into a wall socket our other power source, such as a separate service battery or a solar panel. You can find all the technical data below the product description on this page: www.ctek.com/uk/battery-chargers-12v-24v/vehicle-type/car/solar/cs-free
If you don't have access to a power outlet, the best thing would be to get an external battery that you use to power the CS FREE as it charges the car battery (you would need the USB-C CHARGE CABLE CLAMPS). If that is not possible, you can still hook up the CS FREE to your vehicle battery, without connecting to a power source, but this will drain the CS FREE quickly. How fast it drains the CS FREE depends on the size and state of charge of your vehicle battery.
Do the CS Free and CS one take the same output connection? Struggling to find a connector for the CS Free to connect to the usual yellow/orange trickle charger ‘comfort’ connection?
Hi, Thank you for your message! 😊 They do not use the same connector and there is no adapter from CS FREE to Comfort connect since the comfort connect can only handle 10A and the CS FREE can output up to 20A. If you have further questions, please contact us at support.ctek.com/ or email us at support@ctek.com and we will help you further. Have a great day! ☺
The CS FREE seem to be suited for portable applications, and not have capabilities of a dedicated charger as the CS ONE. I would like to purchase CS ONE; when will a US version become available??
Hi! As of today we do not have any information on a potential US launch of the CS ONE. If you are looking for something that has a similar maximum charging output as the CS ONE, and modes such as Recond and Supply, we would recommend the MULTI US 7002.
When a cable for permanent install on Motorcycles (parked where no mains exist) ?! I've bought one CS Free and now I'm unable to use it on my motorcycle.
Hi. There are no modes on the CS FREE. When you connect it without any power into the CS FREE, it will work as an adaptive booster, charging with 20A. The limit for the CS FREE to start is 3V if voltage in the battery is lower than that the charger will not start, this can happen if you have a lithium battery that have closed down due to Under Voltage Protection. It works as good for both lead acid and lithium. Best regards CTEK Support
So, just to be clear, you are saying that the CS3 I just ordered will not charge a Lithium battery that has shut down due to under voltage protection? Do I still have to resort to clunky methods like an external >14VDC power supply to "wake up" the lithium battery before it will accept a charge from the CS3? @@CTEKBatteryChargers
Portable charging question, When putting the car in storage… Under ground… +22 Celsius Disconnecting the black ground cable from a FULL battery in order to stop parasitic draw… For how long, only the CS Free by itself, will maintain the battery charged?
Hi, Thank you for reaching out to us! 😊 Its hard to tell since it will depend a bit on the battery since they do de-charge by them self and that can differ a bit between different batteries. For the best answer possible, contact us at support.ctek.com/ or visit us at www.ctek.com/
I just bought this and wondered if it conditions batteries? Mine has sulfated so holds a max of 11.7 volts! If I jumpstart the car, it charges the battery up to 12.5v but it drops to 11.7 after 30 minutes.
Hi, Thank you for reaching out! 😊 It does not do reconditioning of batteries, if the battery drops that low so fast I would recommend getting a new battery and then maintaining it with one of our chargers. :)
@@CTEKBatteryChargers ah I see. Well it got me started so I guess it helped. Got it up to 12.1 although not sure how long it would have held it at that voltage. Can your older products fix this battery?
If I power the CS Free from my boat's starter battery, can I leave it wired to the battery full time, then if I need it for a boost then attach the clamp cables from the CS Free to the starter battery?
Hi! It sounds like you want to connect the starter battery to the CS FREE's charge input port and then sort of turn it around to charge the starter battery back up in case you need it. You cannot permanently wire the CS FREE to the starter battery, but yes, technically you could keep a set of USB-C CHARGE CABLE CLAMPS "permanently" connected between the battery and CS FREE's charge input port to keep the unit charged and then, if you get a flat battery, disconnect the CS FREE and instead connect it to the battery through the charge output port (with different cables) to boost charge it. It's not necessary to keep it connected "permanently" though as it will hold its internal charge for up to a year once you've charged it up. So the easiest thing to do would probably be to charge the CS FREE up and just keep it in the boat until you need it. Hopefully I understood your question correctly! Best regards, CTEK Support

Hello, quick question, is there a difference in terms of the charging 'quality' when you charge the battery in your car using ctek free (when connected to the external power supplier) in comparison to charging the battery using ctek one?
Hi. Yes, there is a big difference. The main focus with the CS FREE is to make it possible to charge what ever battery you have - where ever you are. The CS FREE has got a smart combo curve that works fine with both lead acid and lithium (LiFePO4) But as it is a combo curve it is good for both but not specialized on the battery it is connected to. The CS ONE on the other hand can only be used from mains, but have an extremly advanced charge algorithm that will constantly check with the battery and give it what it need. So it will invent the best charge for what ever 12V battery connected. A lithium (liFePO4) battery will be charged in a different way than a lead acid. A smaller battery will be charged with fewer Amps than a bigger one and so on. Fully automatic. I hope this gives you a bit more understanding. Best regards CTEK Support

Hello, I have a dual battery system where the deep cycle auxiliary battery is charged by solar, however, the main battery is not. Can I use the deep cycle auxiliary battery as a service battery to which I can connect the CS FREE in order to charge the main starter battery?
Hi. Yes you can. You will need the additional USB-C CHARGE CABLE CLAMP to connect to the deep cycle auxiliary battery as the giver battery. The CS FREE will use that battery and take power (up to 5A) to recharge and maintain the starter battery. Best regards CTEK Support

Hi, The CS FREE does not have the SUPPLY mode, that some of our other chargers have. SUPPLY mode will provide 13.6V and as much current as the charger can provide. In all other charge modes the chargers need a confirmation that there is a battery connected, otherwise it will not start. That is what makes the CTEK Chargers spark proof and reverce polarity protected. You can not use the CS FREE to power up you amateruradio. Best regards CTEK Support
Hej, är livslängden ett år eller menar nu att batteriet räcker ett år innan man behöver ladda den igen? Sen undrar jag om den har automatiskt recond läge eller hur det funkar?

What happens when the internal battery in the CS FREE goes bad - think I read somewhere after about 100 charges, can you replace that or is charger kaput? Not having mains seems like I will have to recharge weekly thus Chargers internal battery expected life 2 years on 100 charges at 1 per week. So can internal battery be replaced or new charger needs to be bought after it goes bad?
For the time being, there is no way to exchange the battery. It is rated to have 80% capacity left after 300 cycles . One recharge a year would give up to 6 years of usage. Best regards CTEK Support
If the CS FEEE is connected to my car's battery (in maintenance mode without connecting to power source) and I start the car and drive away forgetting to disconnect the CS FREE from the car battery, will that be a problem for the car or the CSFREE?
Hi! I guess that you mean that the CS FREE is placed inside the engine bay and that you're driving away with it still in there. There should be no problem for the charger or the car in terms of the connection itself, but of course there might be external damage made to the CS FREE or the engine bay itself if the CS FREE is kept loose in there while you're driving.
@@CTEKBatteryChargers No electrical damage? The alternator is providing charge additionally along with the CS FREE. If not then I will ensure that the CS FREE is fixed in a stable manner via a mount in the engine bay when connected.
Hi. Depends on the size of the battery - but the internal battery of the CS FREE is 20A big so it is not possible to fully charge a 60Ah battery that is totally drained. The CS FREE will need to be recharged a couple of times before the battery is fully charged. An idea is to recharge the CS FREE through the 12V output in the car whilst driving and then connect to the battery connection points when the car is not used. The CS FREE need at least 3V from the battery to start - this is what makes it spark proof and reverse polarity protected. Best regards CTEK Support
Hi. Yes, it will work fine as a common charger - But if it is broken I recommend you to return it to your dealer for help. The CS FREE comes with 2 years warranty. Best regards CTEK Support
@@CTEKBatteryChargers That is not an answer to the question. The question was can yoy replave the internat battery after for intance 5 years when it has gone bad.
How do I charge my car battery with CS FREE, through the cigarette socket? I bought the usb - cigarette accessory and I put it the IN CHARGE usb c port but doesn't charge my car battery, but the opposite...the car battery charges the CS FREE...any solutions? Don't want to maintain my cars battery with cables clamps always.
Hi. In order to charge your vehicle battery you need to connect to the recommended charge points (see vehicle manual) using the provided battery clamps. You can recharge the internal battery within the CS FREE using the optional USB-C CHARGE CABLE 12V PLUG whilst driving. The reason to why you can not charge the vehicles battery through the 12V output is that the cables between the output and the battery often are thin, and the recommended highest amperage is 8A. The CS FREE can provide up to 20A and that would in worst scenario melt the cables between the output and the battery. I hope this explains why we recommend to connect with clamps. Best regards CTEK Support
@@CTEKBatteryChargers An adapter from CTEK with that maximum amperage of 8A is possible? Its really anoying need to charge the battery through the clamps...
@@classic_matches_10 Hi. There are two issues with this. First one is to "make" an adapter. That is on the to do list. The other thing is that many vehicles closes down the 12V output after some few minutes after the ignition is turned off - in order to minimize the risk of draining the battery through the output. So even if we make an adapter, it is not that many cars that it will work on. Best regards CTEK Support
Hi, The CS FREE has an internal battery that can charge/maintain the battery. The limit is off course the size of the internal battery. When it is out, you need to recharge it. Our test shows that you need to recharge the CS FREE once a week, perhaps even more often if the vehicle is equipped with a lot of electronic components. For longer periods, an external battery will help. I hope this helps. Best regards CTEK Support

@@Entarol Hi, If you want to charge and maintenance charge an almost empty battery, with the CS FREE, only using the internal battery in the CS FREE as the power source, you will probably need to recharge the CS FREE a couple of times before reaching fully charged, After that it can be enough to recharge the CS FREE once a week or even once every second week depending on how much is drawing from the battery.

If you car gives you a warning for low battery, can you use the CS Free to charge it to full by successive charging in battery mode? It seems to me that you can only get the battery energy high enough to start the car? What are the acceptable voltage levels on the USB input?
Hi! When using the CS FREE completely portably you have an Adaptive Booster that gets you going from a flat battery in a safe way. But the CS FREE is also a regular battery charger that you can use for long-term charging when plugged into a wall socket our other power source, such as a separate service battery or a solar panel.
You can find all the technical data below the product description on this page: www.ctek.com/uk/battery-chargers-12v-24v/vehicle-type/car/solar/cs-free
@@CTEKBatteryChargers Yes, but what if you don’t have a wall socket handy, but still have to repark your car twice a week due to cleaning night?
If you don't have access to a power outlet, the best thing would be to get an external battery that you use to power the CS FREE as it charges the car battery (you would need the USB-C CHARGE CABLE CLAMPS). If that is not possible, you can still hook up the CS FREE to your vehicle battery, without connecting to a power source, but this will drain the CS FREE quickly. How fast it drains the CS FREE depends on the size and state of charge of your vehicle battery.
Do the CS Free and CS one take the same output connection? Struggling to find a connector for the CS Free to connect to the usual yellow/orange trickle charger ‘comfort’ connection?
Hi,
Thank you for your message! 😊
They do not use the same connector and there is no adapter from CS FREE to Comfort connect since the comfort connect can only handle 10A and the CS FREE can output up to 20A.

The CS FREE seem to be suited for portable applications, and not have capabilities of a dedicated charger as the CS ONE. I would like to purchase CS ONE; when will a US version become available??
Hi! As of today we do not have any information on a potential US launch of the CS ONE. If you are looking for something that has a similar maximum charging output as the CS ONE, and modes such as Recond and Supply, we would recommend the MULTI US 7002.
When a cable for permanent install on Motorcycles (parked where no mains exist) ?! I've bought one CS Free and now I'm unable to use it on my motorcycle.
Can I use this in booster mode , or charging mode,for lithium batteries like for instance the one in a Ferrari Pista?
Hi. There are no modes on the CS FREE. When you connect it without any power into the CS FREE, it will work as an adaptive booster, charging with 20A. The limit for the CS FREE to start is 3V if voltage in the battery is lower than that the charger will not start, this can happen if you have a lithium battery that have closed down due to Under Voltage Protection. It works as good for both lead acid and lithium. Best regards CTEK Support
So, just to be clear, you are saying that the CS3 I just ordered will not charge a Lithium battery that has shut down due to under voltage protection? Do I still have to resort to clunky methods like an external >14VDC power supply to "wake up" the lithium battery before it will accept a charge from the CS3?

Portable charging question,
When putting the car in storage… Under ground… +22 Celsius
Disconnecting the black ground cable from a FULL battery in order to stop parasitic draw…
For how long, only the CS Free by itself, will maintain the battery charged?
Hi,
Thank you for reaching out to us! 😊
Its hard to tell since it will depend a bit on the battery since they do de-charge by them self and that can differ a bit between different batteries.
For the best answer possible, contact us at support.ctek.com/ or visit us at www.ctek.com/
I just bought this and wondered if it conditions batteries? Mine has sulfated so holds a max of 11.7 volts!
If I jumpstart the car, it charges the battery up to 12.5v but it drops to 11.7 after 30 minutes.
Hi,
Thank you for reaching out! 😊
It does not do reconditioning of batteries, if the battery drops that low so fast I would recommend getting a new battery and then maintaining it with one of our chargers. :)
@@CTEKBatteryChargers ah I see. Well it got me started so I guess it helped. Got it up to 12.1 although not sure how long it would have held it at that voltage. Can your older products fix this battery?
If I power the CS Free from my boat's starter battery, can I leave it wired to the battery full time, then if I need it for a boost then attach the clamp cables from the CS Free to the starter battery?
Hi!
It sounds like you want to connect the starter battery to the CS FREE's charge input port and then sort of turn it around to charge the starter battery back up in case you need it.
You cannot permanently wire the CS FREE to the starter battery, but yes, technically you could keep a set of USB-C CHARGE CABLE CLAMPS "permanently" connected between the battery and CS FREE's charge input port to keep the unit charged and then, if you get a flat battery, disconnect the CS FREE and instead connect it to the battery through the charge output port (with different cables) to boost charge it. It's not necessary to keep it connected "permanently" though as it will hold its internal charge for up to a year once you've charged it up. So the easiest thing to do would probably be to charge the CS FREE up and just keep it in the boat until you need it. Hopefully I understood your question correctly!
Best regards,
CTEK Support
@@CTEKBatteryChargers Yes you understood my question perfectly. Thank You for the response, that makes very good sense to me.

Hello, quick question, is there a difference in terms of the charging 'quality' when you charge the battery in your car using ctek free (when connected to the external power supplier) in comparison to charging the battery using ctek one?
Hi. Yes, there is a big difference. The main focus with the CS FREE is to make it possible to charge what ever battery you have - where ever you are. The CS FREE has got a smart combo curve that works fine with both lead acid and lithium (LiFePO4) But as it is a combo curve it is good for both but not specialized on the battery it is connected to. The CS ONE on the other hand can only be used from mains, but have an extremly advanced charge algorithm that will constantly check with the battery and give it what it need. So it will invent the best charge for what ever 12V battery connected. A lithium (liFePO4) battery will be charged in a different way than a lead acid. A smaller battery will be charged with fewer Amps than a bigger one and so on. Fully automatic. I hope this gives you a bit more understanding. Best regards CTEK Support
Hello, so to clarify,if both products CS One and CS Free were connected to the mains, the CS one charging is more advanced than the CS free ?
How much CS FREE handles cold winter times, if i dont have warm place to store CS FREE? 🥶
Here is now -32°C outside.
Hi,

The CS FREE can handle temperatures down to -20* C

Hello, I have a dual battery system where the deep cycle auxiliary battery is charged by solar, however, the main battery is not. Can I use the deep cycle auxiliary battery as a service battery to which I can connect the CS FREE in order to charge the main starter battery?
Hi. Yes you can. You will need the additional USB-C CHARGE CABLE CLAMP to connect to the deep cycle auxiliary battery as the giver battery. The CS FREE will use that battery and take power (up to 5A) to recharge and maintain the starter battery. Best regards CTEK Support

Does CS FREE have the "supply" and "wake up" features of the CS ONE? Can it be used to revive a dead battery?
Hi, The CS FREE does not have the SUPPLY or the WAKE UP. It needs at least 3V from the battery. Best regards CTEK Support
Can I get 12 volts out to charge my amateurradio With CS Free? I use the radio Anytone 878. Thanks in advance
Hi, The CS FREE does not have the SUPPLY mode, that some of our other chargers have. SUPPLY mode will provide 13.6V and as much current as the charger can provide. In all other charge modes the chargers need a confirmation that there is a battery connected, otherwise it will not start. That is what makes the CTEK Chargers spark proof and reverce polarity protected. You can not use the CS FREE to power up you amateruradio. Best regards CTEK Support
Hej, är livslängden ett år eller menar nu att batteriet räcker ett år innan man behöver ladda den igen?
Sen undrar jag om den har automatiskt recond läge eller hur det funkar?
Hej. När det interna batteriet i CS FREE är uppladdat håller det laddningen i upp till ett år. Det kan variera beroende på i vilken temperatur laddaren lagras. CS FREE har inget RECOND läge. Med vänlig hälsning CTEK Support
What happens when the internal battery in the CS FREE goes bad - think I read somewhere after about 100 charges, can you replace that or is charger kaput?
Not having mains seems like I will have to recharge weekly thus Chargers internal battery expected life 2 years on 100 charges at 1 per week. So can internal battery be replaced or new charger needs to be bought after it goes bad?
For the time being, there is no way to exchange the battery. It is rated to have 80% capacity left after 300 cycles . One recharge a year would give up to 6 years of usage. Best regards CTEK Support
@@CTEKBatteryChargers6 years of usage with one recharge a year? Did you get that right?
@@car-dcdthey meant per week, presumably
@@car-dcd Yes, if you dont use it! It only needs charging once per year.
If you do use it, then you would need to recharge it asap.
If the CS FEEE is connected to my car's battery (in maintenance mode without connecting to power source) and I start the car and drive away forgetting to disconnect the CS FREE from the car battery, will that be a problem for the car or the CSFREE?
Hi! I guess that you mean that the CS FREE is placed inside the engine bay and that you're driving away with it still in there. There should be no problem for the charger or the car in terms of the connection itself, but of course there might be external damage made to the CS FREE or the engine bay itself if the CS FREE is kept loose in there while you're driving.
@@CTEKBatteryChargers No electrical damage? The alternator is providing charge additionally along with the CS FREE. If not then I will ensure that the CS FREE is fixed in a stable manner via a mount in the engine bay when connected.
No, there will be no electrical damage :)
@@CTEKBatteryChargers Thanks - One more of your great devices to own!
Er det mulig å bytte ut det interne batteriet i CS Free?
Hi,
Thank you for reaching out! 😊
Unfortunately the battery is not replaceable.
@@CTEKBatteryChargers Thats to bad. This means when the internal battery is broken the whole unit is useless!
Hi! Can you charge full a dead battery with CS FREE own battery?
Hi. Depends on the size of the battery - but the internal battery of the CS FREE is 20A big so it is not possible to fully charge a 60Ah battery that is totally drained. The CS FREE will need to be recharged a couple of times before the battery is fully charged. An idea is to recharge the CS FREE through the 12V output in the car whilst driving and then connect to the battery connection points when the car is not used. The CS FREE need at least 3V from the battery to start - this is what makes it spark proof and reverse polarity protected. Best regards CTEK Support
@@CTEKBatteryChargers thanks
Hi, if the CS Free internal lithium battery is bad, can we still use it as a standard charger, i.e., with inlet adapter plugged in.
Hi. Yes, it will work fine as a common charger - But if it is broken I recommend you to return it to your dealer for help. The CS FREE comes with 2 years warranty. Best regards CTEK Support
Are the battery replaceable? Let's say 5 years from now and it starts to turn bad.
@@Kammaflaje Hi, if the battery break now, we will replace the whole charger. Best regards CTEK Support

How do I charge my car battery with CS FREE, through the cigarette socket?
I bought the usb - cigarette accessory and I put it the IN CHARGE usb c port but doesn't charge my car battery, but the opposite...the car battery charges the CS FREE...any solutions? Don't want to maintain my cars battery with cables clamps always.
Hi. In order to charge your vehicle battery you need to connect to the recommended charge points (see vehicle manual) using the provided battery clamps. You can recharge the internal battery within the CS FREE using the optional USB-C CHARGE CABLE 12V PLUG whilst driving. The reason to why you can not charge the vehicles battery through the 12V output is that the cables between the output and the battery often are thin, and the recommended highest amperage is 8A. The CS FREE can provide up to 20A and that would in worst scenario melt the cables between the output and the battery. I hope this explains why we recommend to connect with clamps. Best regards CTEK Support
@@CTEKBatteryChargers An adapter from CTEK with that maximum amperage of 8A is possible? Its really anoying need to charge the battery through the clamps...
@@classic_matches_10 Hi. There are two issues with this. First one is to "make" an adapter. That is on the to do list. The other thing is that many vehicles closes down the 12V output after some few minutes after the ignition is turned off - in order to minimize the risk of draining the battery through the output. So even if we make an adapter, it is not that many cars that it will work on. Best regards CTEK Support
Hi, can the CS FREE maintain a battery on its own without the help of an external battery?
Hi, The CS FREE has an internal battery that can charge/maintain the battery. The limit is off course the size of the internal battery. When it is out, you need to recharge it. Our test shows that you need to recharge the CS FREE once a week, perhaps even more often if the vehicle is equipped with a lot of electronic components. For longer periods, an external battery will help. I hope this helps. Best regards CTEK Support
@@CTEKBatteryChargers Hi,
Thank you very much for all this information which will be useful to me. Kind regards.

@@Entarol Hi, If you want to charge and maintenance charge an almost empty battery, with the CS FREE, only using the internal battery in the CS FREE as the power source, you will probably need to recharge the CS FREE a couple of times before reaching fully charged, After that it can be enough to recharge the CS FREE once a week or even once every second week depending on how much is drawing from the battery. I hope this helped. Best regards CTEK Supportharged, After that it can be enough to recharge the CS FREE once a week or even once every second week depending on how much is drawing from the battery.

@@Entarol Hi, that will happen automatically. When you attach the charger it first have to fully charge before it can maintain. When fully charged it will by default go to maintenance mood if there is still power left in the charger. If the battery is fully charged - maintenance will start at once. Best regards CTEK Support

Portable charger??? Which car battery you can charge with 66wh capacity? Maybe a fully charged laptop…😮
To use the CS FREE portably when you're far away from a power outlet, we recommend you to use it with the SOLAR PANEL CHARGE KIT or the USB-C CHARGE CABLE CLAMPS and a separate service battery. You could still top up your vehicle completely portably, without any accessories, but this would drain the CS FREE very quickly.
