Top 10 FAQ

  • D250SA: Can I use D250SA for lithium batteries?
    See answer

    No, it works only with lead acid batteries.

  • PRO60: Why does it have different charging modes available when it has adaptive charging?
    See answer

    The PRO60 can assess the battery size not the technology.

  • PRO60: What is adaptive charging?
    See answer

    The PRO60 can work out the battery size and applies the safest, quickest charge rate for the battery its connected to.

  • CT5 POWERSPORT: Is POWERSPORT a simpler charger than the MXS 5.0? It has only three lights while the MXS 5.0 has eight.
    See answer

    No. Both chargers contain an eight-stage charging programme, but they show this differently. On the MXS 5.0 a light shows for every step, and the voltage and power curve is shown above and below the lights. On the POWERSPORT we've chosen to reduce the number of lights and instead just show which phase the charger is currently in – Check, Charge or Care. However, MXS 5.0 is a more powerful charger than POWERSPORT.

  • CTX BATTERY SENSE: Can I connect even if I've forgotten my serial number?
    See answer

    Yes – you must disconnect the sender from the battery for at least 30 seconds and then reconnect. Follow the "lost code" guide in the app.

  • CTX BATTERY SENSE: Where can I find more information than what's shown in the manual?
    See answer

    For more information, see www.ctek.com

  • CTX BATTERY SENSE: How do I know whether I've got Bluetooth 4.0?
    See answer

    This is not generally obvious on your phone. Check with your phone retailer.

  • CTX BATTERY SENSE: Can I connect my charger to Battery Sense?
    See answer

    No, you cannot. You need a CTEK accessory – for more information see

  • CT5 TIME TO GO, CT5 TIME TO GO GULF EDITION: Can I use the charger for long term maintenance?
    See answer

    Yes, you can. The charger switches automatically to maintenance charging when the battery is fully charged.

  • D250SE: How do I activate the Smart alternator setting?
    See answer

    The D250SE has a wiring harness with a black and a red wire, the red wire must be connected to an Ignition signal wire +15 (DIN 72552).

  • MXS 3.6, M45, MXS 3600: and is lit (flashing rapidly) simultaneously

    Explanation 1: Bad connection.
    Test: Move the clamps and make sure there is no loose connection in the quick connector, CONNECT.

    Explanation 2: The charger is working in the desulphation phase.
    Test: Leave the charger to charge for 24h (with some supervision). If the charger does not start charging (one of the LED’s are lit) within 24h the battery is in a very poor condition.

  • XC 0.8: and is lit (flashing rapidly) simultaneously and there is a ticking sound

    Explanation 1: Bad connection.
    Test: Move the clamps and make sure there is no loose connection in the quick connector, CONNECT.

    Explanation 2: The charger is working in the desulphation phase.
    Test: Leave the charger to charge for 24h (with some supervision). If the charger does not start charging (one of the LED’s are lit) within 24h the battery is in very poor condition.

  • XC 0.8: switches to after the charge has been stopped

    Explanation: When the charger restarts the battery voltage is monitored. If the battery voltage is above 6,5V, the charging will not commence. When the battery is between 6,5V and 7,2V it is considered as fully charged. The charging will automatically start again when the battery voltage drops below 6,5V.

  • MXS 3.6, M45: switches to after the charge has been stopped

    Explanation: When the charger restarts the battery voltage is monitored. If the battery voltage is above 12,9V, the charging will not commence. When the battery is between 12,9V and 14,4V it is considered as fully charged. The charging will automatically start again when the battery voltage drops below 12,9V.

  • MXS 5.0 CHECK, XS 0.8, MXS 5.0, MXS 5.0 POLAR, MXS 10EC, MXS 10, MXS 5.0 TEST&CHARGE: is lit

    Explanation 1: Reverse polarity.
    Test: Make sure that the + cable/clamp is connected to the + terminal and the – cable/clamp is connected to the – terminal.

    Explanation 2: Loads are connected to the battery which requires more power than the charger can provide.
    Test: Turn off or disconnect the loads when charging.

    Explanation 3: The charger is not connected to a 12V battery.
    Test: Test with a fresh 12V battery.

    Explanation 4: The charge cycle is interrupted in step 1.
    Test: Test to restart the charge cycle, if it still fails in step 1 the battery is sulphated and needs to be replaced.

    Explanation 5: The charge cycle is interrupted in step 4.
    Test: Test to restart the charge cycle, if it still fails in step 4 the battery is can’t be charged and needs to be replaced.

  • MXTS 70/50: is lit

    This indication always has an explanation in the Ah & info display.

    E01: Reverse polarity.
    Test: Make sure that the + cable/clamp is connected to the + terminal and the - cable/clamp is connected to the - terminal.

    E02: Over voltage. The battery connected has a higher voltage than the selected charge program.
    Test: Make sure that the battery and the selected charge program corresponds to each other.

    E03: Time out step 1: Desulphation. The battery is sulphated and can´t be charged correct.
    Test: Try to restart the charge cycle, if it still fails in step 1 the battery is sulphated and needs to be replaced.

    E04: Time out step 2. Soft start. The battery can´t be charged correct.
    Test: Try to restart the charge cycle, if it still fails in step 1 the battery is sulphated and needs to be replaced.

    E05: Analyze. The charger can´t keep the charge.
    Test: Remove all parallel loads on the battery and restart the charge cycle. If the analyze fails again the battery needs to be replaced.

    E06: battery overheated. The charger has detected a too warm battery, over + 60 °C. Push Pause/Start to resume charging when temperature is below.
    Test: Make sure that it is not the ambient that is too warm. If that is not the case the battery need to be replaced.

    E07: Low battery voltage in supply program. The battery connected has too low voltage to continue. The battery connected is either a 12V and the charger is in 24V mode or the parallel loads are too high.
    Test: If a 12V battery is connected check if the unit is in 24V mode. Try to remove all parallel loads.

    E08: Over current in supply. The charger has switched off the output due to too high current.
    Test: Make sure that the clamps not are shortened. Also check if there are massive parallel loads on the battery.
