CTEK Smarter Chargers:

Smartly maintain the battery in prime condition through a series of 4 to 8 steps in our unique charging process. The chargers constantly monitor the battery to understand the battery condition and then act accordingly: disulphate, revive, charge, condition and maintains. The unique reconditioning step allows the battery to recover quickly and last longer.

They charge and maintain batteries with a patented system that’s battery and electronics friendly. The patented desulphation function can extend the life of your current battery 2-3 times that of its normal life.

CTEK Smarter Chargers also regulate the main voltage to protect sensitive and expensive electronic and audio equipment. They even have a backup power supply that allows you to charge vehicle batteries without losing your vehicles program settings.

These elegant, compact chargers are:

  • water and shock resistant,
  • UL-approved for outside use- they can perform under extreme weather environments, with a temperature range of (-4°F to +122°F).
  • Immune to power line fluctuations so your batteries will be charged efficiently with no interruption in their charging cycles
  • The patented float/pulse charging allows ‘set and forget’ for months at a time without harming the battery. Motorists do not need to have a specific knowledge of batteries or their charging methods. There is no need to even disconnect the battery during use – it’s simply ‘plug and play’.

CTEK chargers’ safety systems feature a spark-free, short-circuit-proof design that prevents reverse polarity. They  won’t allow you to damage your vehicle’s electrical system, even if you hook them up backwards. Conveniently, the red alarm light on the charger alerts you if it wasn’t attached correctly so that you can get it connected properly.

CTEK’s range of Smarter Chargers suits all types of lead-acid batteries for vehicles of all sizes and types including cars, motorbikes, marine vessels, agricultural vehicles, motor homes, lawn mowers, and more.
