Power Train PTC12V6A7SL smart battery charger - Designed to charge light, medium and heavy duty batteries, it is perfect for charging and maintaining 12v - Car, 4wd, RV, Marine and light commercial 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. The on board micro-chip controls the unique pulse algorithm for the charging cycle, which helps reduce the oxidation on the battery plates and evens the consistency of the electrolyte. It minimises temperature whilst charging, 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.

A sophisticated charger system for deep cycle batteries, making them ideal for Motorhomes, Caravan, Horsetrucks, etc...

  • Battery Range (Maintain) up to 1000CCA or 200A/h
  • 5 year warranty
  • Deep Cycle Batteries: Wet flooded deep cycle batteries should be recharged overnight at a rate equivalent to 10% of the battery capacity. State of charge should be regularly checked using a hydrometer or multimeter to ensure optimum battery condition is achieved.
  • Deep Cycle AGM: AGM batteries should be charged using a charger with a mode switch for AGM type batteries. It is recommended to use a charger, current limited to 20% or 0.2C of the batteries capacity at a charging voltage of between 14.6 – 14.8V following deep cycle use, or 13.6V – 13.8V for standby use. Charging should be paused if the battery or ambient temperature exceeds 50°C.
