Auto Charger For Vehicles With Start-Stop Function

Fast Start-Stop charging

The CT5 START-STOP battery charger and maintainer has been specially designed to charge and maintain batteries in Start/Stop vehicles.

Start-Stop technology is great for the environment but it can put a considerable strain on your battery, especially if it’s in an older car. By keeping the battery fully charged, you can take full advantage of all the Start-Stop technology benefits, such as better fuel efficiency and lower CO2 emissions. If you only make short journeys, use the CT5 START-STOP once a month to keep your battery in peak condition. And if you’re going away on holiday, just connect the charger to the battery to make sure your car’s ready to go when you return.

Features:

  • Fully optimised for cars with Start/Stop technology, e.g. AGM and EFB batteries
  • No buttons to press – fully automatic charging
  • Simple to use with an easy to understand display
  • Reverse polarity protected
  • Compact rugged design – splash resistant & dust-proof
  • Supplied with insulated croc-clip connectors & eyelet connector lead
  • 5-year warranty

CTEK - Frequently Asked Questions

CTEK chargers need some counter voltage to start providing tension/current.  If there's a poor connection between the charger and the battery, charging will not start. If the battery is below 2 volts, charging will not start.

Yes, CTEK chargers are designed to fully charge a battery and then automatically switch over to long term maintenance. Before leaving the charger unattended for a long time, ensure that the battery is fully charged, as indicated by the green LED.

There is no reason to disconnect or remove the battery from the vehicle, or open the battery caps while charging. CTEK chargers are spark proof, reverse polarity protected and electronically safe.

The charger stays in float maintenance mode for 10 days, keeping the battery topped up using the minimum level of current.

After 10 days, the program moves on to the last stage – pulse level – for long term maintenance.

Yes, this is normal when the charger is working hard in the bulk charge phase. The heat is generated in certain circumstances, depending on the battery that's being charged.

The charger does not necessarily heat up when it's charging other types of battery.

Choose charger depending on the size of your battery.

Charging with a smaller charger than recommended will take longer time and will not optimally extend the battery life and performance.

If your battery has an Ah rating that exceeds that of the charger limit it could mean that the charger will be unable to charge the battery sufficiently and may even lead to it becoming discharged.

Charging with a bigger charger than recommended will not result in a completely charged battery and will not optimally extend the battery life and performance.

No, Lithium batteries need a different type of charger to lead-acid batteries. We do not recommend using a CTEK charger designed for lead-acid batteries.

Charging lead-acid batteries with a Lithium charger will not give the best results and cannot be recommended.

CTEK's new CS FREE can be used without mains power connected.
