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.
If no battery or if the battery voltage is too low the led will start to flash to indicate the unit has entered power save mode.
Test: Test the charger on a fresh battery.
No. 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 START/STOP we've chosen to reduce the number of lights and instead just show which phase the charger is currently in – Check, Charge or Care. START/STOP has no programme selection. Instead, when it is in contact with a battery it starts as soon as it's plugged into a wall socket.
The D250SA has a wiring harness with a black and a red wire, the black wire must be earthed / grounded to change the charging voltage for AGM.
CTEK chargers needs some counter voltage to start providing tension/current.
If the connection is poor between the charger and the battery, the charging does not start.
If the battery is completely flat, 0V, the charging does not start.
If you think the product is faulty and within warranty:
1. Connect the product to another battery
2. Connect the product to mains
3. Check if the LEDs light up
4. Press the mode button and see if it works
If you still believe the charger is faulty, please return it with the receipt to the retailer.
Yes. START/STOP is optimized for use with 12 V EFB (Enhanced Flooded Battery) and AGM batteries, but it can charge ordinary 12 V lead-acid batteries as well.
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.
Measuring the voltage for estimating the charge status of a Lead Acid battery can only be done when the battery has been at rest for a certain period -sometimes more than 10 hours. This situation is likely to occur after charging the battery or after a ride with the car for instance. Battery Sence takes this into consderation when calculating the charge status.
If your cigarette lighter socket is connected to the battery even when the ignition isn't on, you can charge the battery that way. You need a CONNECT Cig plug or a INDICATOR Cig plug for this.
Explanation: The plug has to be connected for the LED to be lit.
