Accucharger 2 6V/12v Battery Charger
Part No: Accucharger-2

  • 6V/12V 2A fully automatic battery charger and maintainer
  • No more flat batteries when you come to start the car.
  • Store your car for long periods with the battery 100%.
  • Full charge applied and then maintained - automatically!
  • Designed to be left connected all the time the car is not in use.

  • LED indicators of charge condition.
  • Fold away hook to hang it up when in use.
  • Supplied with crocodile clip lead, spade terminal lead and carry bag.
  • At last a battery charger is available that will intelligently charge and maintain all car lead acid batteries. The ACCCHARGER 2 battery charger is the answer to keeping a 6 or 12 volt battery in tip-top condition whenever thebattery is not used.
    Basic battery chargers simply apply an uncontrolled current/voltage that restores charge to the battery. However, they cannot charge a battery accurately to full charge, may only partially charge a battery and can most certainly overcharge which may result in gassing and loss of water. Consistently under or over charging a lead acid battery will reduce its lifespan. Older cars have charging systems that are not optimised for modern hybrid batteries so may not provide full charge.
    ACCUCHARGER 2 is an advanced fully automatic battery charger and maintainer for all 6V/12V lead acid batteries, including conventional, hybrid and fully sealed starter batteries, GEL type and deep cycle and leisure batteries.

    The CORRECT way to charge a flooded wet cell or gel type lead acid battery is through a controlled multi-stage process. Three stage charging is the method most lead acid battery manufacturers recommend as the best and most efficient way to return full capacity to the battery and extend battery life. The Car battery charger/maintainer is a three stage charger that operates as follows (12V levels shown for example):

    Constant Current Charging or Bulk Charge Mode. Assuming the battery is starting in a discharged state, the charger is operating in constant current mode, where the charger current is maintained at a constant value of 1.8 Amps and the battery voltage is allowed to rise as it is being recharged. Approximately 80% of battery capacity is returned in the constant current region.

    Constant Voltage - Absorption Mode When the battery voltage reaches 14.3 Volts (just below the point where gassing will start), ACCUCHARGER 2 switches mode to hold the voltage constant at this level whilst the battery current is allowed to reduce. It is this region where the last 20% of battery capacity is returned. This voltage level is maintained until the battery current reduces to 200mA.

    Constant Voltage - Float Mode.  At the point where the current is reduced to 200mA, ACCUCHARGER 2  enters float mode. In float mode the voltage on the battery is maintained at 13.5 Volts. This voltage will maintain the full charge condition in the battery without gassing the electrolyte or overcharging the battery. If the charger detects a current drain greater than 200mA during this float phase then the full charge cycle is restarted. ACCUCHARGER 2 can therefore be left permanently connected to the battery of the car and will keep it fully and correctly charged even if you have accessories such as clocks and alarms systems connected to the car. will also charge and maintain unconnected batteries.

    ACCUCHARGER 2 is supplied complete with ring terminal lead set for smaller batteries, crocodile lead set for conventional car batteries and fitted with UK mains plug. 220-240 Volts only.  2 year Guarantee


    (Please NOTE: ACCUCHARGER 2 is NOT suitable for charging NiCad or Dry Batteries)

    very efficient conditioner for cars not in daily use, this is the second one bought, pleased to see the in line connector has been upgraded and is now as robust as the charger itself

    Does all that is required to charge and maintain battery on my infrequently used classic car. The simple display lights mean that I can see instantly the battery condition.
