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).

  • Can I use a SMARTPASS without a D250S DUAL?

    Yes you can. If you do not need a charging function to the service battery, SMARTPASS can be a good solution to provide the service battery with current, especially if you use the service battery while charging (fridge, microwave oven etc.).

  • D250SA: Can I use D250SA for lithium batteries?

    No, it works only with lead acid batteries.

  • D250SE: Can I use D250SE for lithium batteries?

    Yes it works both with lead-acid and lithium (12V LiFePO₄) batteries.

  • SMARTPASS 120: Can the starter battery and the service battery be different types of battery?

    Yes, (lead acid)

  • SMARTPASS 120S: Can the starter battery and the service battery be different types of battery?

    Yes.

  • CTEK MONITOR
    Can the CTEK MONITOR monitor my engine starting battery as well as my service battery?

    No, it cannot. The service battery is in continuous use, and so needs continuous monitoring. The starter battery, however, is subject only to periodic heavy loads followed by float charging, and so does not need to be monitored.

  • CTEK MONITOR
    Do I need to disconnect my CTEK MONITOR when I leave the vehicle for long periods?

    No. The CTEK MONITOR is designed to be permanently connected to the battery. It is independently fused, and draws only 1.5mA from the battery. At such a low current, it would take several years to discharge a typical fully-charged service battery.

  • CTEK MONITOR
    I have a 500W appliance. How do I know what current it will draw?

    Divide the power rating by the nominal supply voltage to find the current. So, for example, your 500W appliance will draw 500W/12V Amps from a nominal 12V battery: i.e. about 42Amps

  • CTEK MONITOR
    I have another voltmeter on my vehicle which shows a different value to the CTEK MONITOR indication.

    The CTEK MONITOR very accurately measures the voltage directly across the battery terminals. Other voltmeters may read differently owing to volt drops in the wiring.

  • CTEK MONITOR
    My battery is made up of a bank of several batteries. Is that a problem?

    Not as long as the combination produces a nominal 12 volts, and all the current drawn from the bank passes through the shunt.
