The wrong charger can damage the right battery.
Marine batteries are not all built the same. Starting batteries, deep-cycle batteries, AGM batteries and Gel batteries can need different charging behaviour. A one-size charger approach can shorten battery life and create costly comebacks.
CTEK smart chargers support correct battery care by adapting charging profiles to suit the battery type and application. For dealers, workshops and boat owners, that means better protection for expensive marine battery banks.
Pair the right battery with the right CTEK charger.
