12 Volt - 7 Stage - 6 Amp Smart Battery Charger


Perfect for charging and maintaining 12v - Car, 4wd, RV, Marine and light commercial batteries.

The Power Train PTC12V6A7SL smart battery charger is designed to charge light, medium and heavy duty batteries. Idea for deep cycle batteries.

The PTC12V6A7SL charger is controlled by a sophisticated on board programming, enabling quick and safe charging as it implements a 7 stage charging algorithm, battery charger uses an on board micro-chip to control its unique pulse algorithm for the charging cycle, this helps reduce the oxidation on the battery plates and evens the consistency of the electrolyte, minimises temperature whilst charging, and recovers the battery capacity and extends battery life.

This Automatic charger can remain connected to the battery without risk of overcharging, as the internal electronics will stop the charging when the battery is fully charged. Once the battery is fully charged, the charger monitors the battery voltage and continues to top up & to maintain the battery, keeping it fully charged and ready for use.



  • The PTC12V6A7SL is packaged with standard charger clips, along with an interchangeable ring terminal charging
  • Heavy duty design
  • IP65 Water resistance rated
