    Powerful 15A battery charger & maintainer

    For the home or the workshop

    The PRO15S is a powerful and fully automatic 15A battery charger and maintainer, compatible with any 12V battery, including Lithium-Ion (LiFePO4). Safe, strong & robust, it can handle heat, dust & humidity. Combining fast and powerful charging with long-term maintenance capability, the PRO15S is the ideal charger for the workshop, the car, the caravan or the boat.

    Advanced technology will ensure that a safe, fast charge is delivered to exactly meet the needs of the individual battery. The PRO15S has a dedicated reconditioning programme to restore battery life & recondition flat batteries. SUPPLY mode can act as a secure 12V power source if the battery needs to be disconnected from the vehicle. The PRO15S has low voltage & current ripple, so it’s safe for the battery & the vehicle’s delicate electronic systems. Fully automatic & easy to use, it’s also very simple to connect, spark proof and reverse-polarity protected to protect the user & also the battery. Whilst the PRO15S is lightweight & portable, the rugged, impact-resistant casing means it can also handle the toughest environments.

        FAQ
        No LED’s are lit on the top row when the charger is connected to both the power outlet and the battery   ×
        The LED’s on the bottom row are lit and you can change charging mode. None of the LED’s in the top row, indicating charging status, are lit.

        Explanation: The battery voltage could be under 2 +/- 0.5V.
        Test: Try to charge the battery in Supply mode for approximately 5 min. Then try regular charging.
        Test: Test the charger on a fresh battery.
        The error LED 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: The clamps are short circuited.

        Explanation 3: For chargers of the older type the error mode is flashing when only the plug is connected.
        Can you charge a lead acid battery with the Lithium mode?   ×
        We would not recommend that you do. Our ‘Lithium’ mode has been specially developed to work with lithium (LFP / LiFePO4) battery chemistries – this mode will not fully charge a lead acid battery.
        I have charged my lead acid battery with lithium have I ruined the battery.   ×
        The battery will not be ruined but it will not be fully charged.
        No LED is lit when the charger is connected only to the power outlet   ×
        Explanation: One of the LED’s at the lower row should light up when the charger is connected to the power outlet.
        Test: Make sure that there is power from the power outlet.
        Can I use lithium for lead acid and vice versa?   ×
        No - CTEK recommend the correct charge mode be used at all times.
        The charger has gone into maintenance mode but cannot see that the recond is completed?   ×
        The Recond program starts with the normal charging program but has a recondition phase inserted after the charging, automatically followed by the maintenance mode. The Recond light “R” on the upper row may be tricky to see, as it will be lit after the third charging lamp, and turns off after the recondition is done, (lasts 0,5h – 4h) and after that the 4th, green maintenance light will be lit.
        is flashing, then turns into error mode   ×
        Explanation: The battery is probably too sulphated to revive. The battery is faulty and it is time to change it.
        is lit and then turns into error mode   ×
        The analysis phase is testing if the battery can retain the charger given.

        Explanation 1: Large loads are connected to the battery and are draining the voltage.
        Test: Disconnect the battery and try charging again.

        Explanation 2: The battery cannot retain the charge given.
        Test: The battery needs replacing.
        Is there a temp sensor? How does it act?   ×
        The temp sensor is within the charger and automatically adjusts charge voltage for optimum charge in any condition.
        No LED is lit when the charger is connected only to the battery   ×
        Explanation: The plug has to be connected for the LED to be lit.
