  • INDICATOR EYELET M8, INDICATOR PANEL 3.3M, INDICATOR EYELET M6, INDICATOR CLAMP, INDICATOR CIG PLUG, INDICATOR PANEL 1.5M: I have a INDICATOR connected to the battery all the time. Is there any risk of the battery discharging?
    See answer

    No, the purpose of the indicator is to allow you to quickly and easily see whether the battery must be charged, thereby reducing the risk of the battery being damaged because of being discharged. The INDICATOR uses about 1.5mA. Than gives 1,5 Ah /month. An average self-discharge for a battery is approx. 10 Ah/month.

  • CONNECT CIG PLUG: Can I use your CONNECT CIG PLUG to charge the battery through the cigarette socket in my car?
    See answer

    Yes, but you should check that you have voltage to the socket even if the vehicle is switched off. If, for example, you can charge a mobile phone or get a GPS to work when the car ignition is switched off, you can also charge the car battery this way.

  • CTX BATTERY SENSE: Battery Sense Software update
    See answer

    12th July Issues have been reported with the latest update on our Battery sense app – our developers are currently working hard to rectify the issue. In the mean time we have taken the decision to roll back to the previous version of the app, We have been assured this will happen over the next few days - iOS first then Android to follow.

  • Charger functions, MXS 5.0 TEST&CHARGE: I have a CTEK charger. It used to work well, but now nothing happens when I press the mode button. I can't change between the "MC", "CAR” and "SNOWFLAKE” modes. What can I do?
    See answer

    If you can't change the charging mode by pressing the mode button regardless of which battery you are trying to charge, the charger is probably faulty. If you still have the warranty, I recommend you go to your dealer with the charger, the receipt and a completed warranty claim form.

  • INDICATOR EYELET M8, INDICATOR PANEL 3.3M, INDICATOR EYELET M6, INDICATOR CLAMP, INDICATOR CIG PLUG, INDICATOR PANEL 1.5M: My COMFORT INDICATOR is flashing. Is that OK?
    See answer

    INDICATOR always flashes. It is to save battery power, as flashing draws less current tha a steady light.

  • Charger settings: AGM / * Snowflake
    See answer

    Because the AGM battery has a low internal resistance it can accept a higher charge voltage, in this mode the Bulk charge rate is 14.7v which is the optimum chare rate for the AGM type battery. In cold weather the internal battery chemistry slows considerably, this leads to the battery being reluctant to accept charge at a normal rate. By raising the charge rate to 14.7 (15v on the Polar) the battery accepts charge more readily

  • Batteries: EFB or ECM
    See answer

    EFB stands for Enhanced Flooded Battery, ECM stands for enhanced charge mat, two different names for exactly the same type of battery and both are similar in set up to a standard Flooded battery. There are some design changes with this technology, active plate material is more dense, anti corrosion treatment for negative and positive grid and lower specific gravity to improve charge acceptance are just some of the differences.The EFB battery provides a more cost effective battery solution over more expensive AGM type batteries.

  • INDICATOR EYELET M8, INDICATOR PANEL 3.3M, INDICATOR EYELET M6, INDICATOR CLAMP, INDICATOR CIG PLUG, CTX INDICATOR PLUG 12V, CTX INDICATOR EYELET M8, INDICATOR PANEL 1.5M: I have a INDICATOR connected to the battery in my car. The red lamp flashes even after I've fully charged the battery. Should it do this? I thought the INDICATOR would be green when the battery is fully charged?
    See answer

    The CTEK INDICATOR is exactly what the name says – an indicator. It provides a snapshot of the system voltage level and works best when the battery has reached a rest level (this can take up to a few hours to reach after the battery was used). As soon as you open a car door or turn on the ignition, the battery voltage vill temporarly drop and the indicator shows yellow or even red. To make things easier, you can position the INDICATOR where you can see it without having to unlock or use any voltage in the car.

  • D250SE, D250SA: Do I need to use solar?
    See answer
