CTEK's Unique 6 Step Charging

Step 1 Desulphation
Pulsing voltage removes sulphates from the lead plates of the battery restoring the battery capacity.
Step 2 Bulk
Charging with maximum current until approximately 80% battery capacity.
Step 3 Absorption, Ready to Use
Charging with declining current to maximise up to 100% battery capacity.
Step 4 Analyse
Tests if the battery can hold charge. Batteries that cannot hold charge may need to be replaced.
Step 5 Float, Fully Charged
Maintaining the battery voltage at maximum level by providing a constant voltage charge.
Step 6 Pulse, Maintenance Charging
Maintaining the battery at 95-100% capacity. The charger monitors the battery voltage and gives a pulse when necessary to keep the battery fully charged.
About CTEK Chargers
CTEKS chargers are the smallest battery chargers in the world, designed and developed in Sweden. They are highly versatile, easy to use, compact battery chargers and proven award winners.
CTEK chargers are ideally suited to a wide range of applications, including cars, caravans, motorbikes, trucks, boats, jet skis, ride on mowers, tractors and virtually any other situation where a lead acid, traction or leisure battery is used.
CTEK chargers are both rechargers where batteries are low, and maintenance chargers where you want the charge to maintain the state of the battery over long periods.
CTEK chargers are supplied OE to Porsche, Ferrari, Aston Martin, Bentley, BMW, Lamborghini and Harley Davidson.
