The CTEK XC 800 is the battery charger that can give your old car a new lease on life. This is a complete 6V battery charger in a diminutive format that charges everything from small batteries of 1Ah up to large tractor batteries.

Features & Benefits

  • Three step, fully automatic switch mode model.
  • Charges lead-acid batteries (Wet, MF, GEL and AGM) from 1.2Ah to 32Ah, 1.2-100Ah maintenance charging.
  • Maintenance pulse charging increases battery life and gives superb performance.
  • Charges even drained batteries. Pulse recover of slightly sulphated batteries.
  • Low back current drain, low ripple and input voltage independent (170-260V).
  • High efficiency: 85%
  • Delivered with two interchangeable connection leads, one with clamps, and one with eyelet terminals.
  • The charger can be connected for months, ideal for seasonal vehicles.

*) Back current drain is what drains the battery if the charger is connected without the power cord connected. The XC 800's extremely low back current drain corresponds to < 1 Ah per month. Many other chargers have 1 Ah per day.

**) Ripple denotes the amount of interference there is to the current and voltage. A high current ripple heats the battery and shortens its life. A linear charger has a current ripple of 70 - 400% which is much larger than the maximum 5% for a modern sealed battery. Voltage ripple could harm other equipment, which is connected to the battery. XC 800's ripple is only 2%. The battery gains a long service life and there is no risk of damage to other electronic devices connected to the battery.
