Versatile compatibility

The DECA FL 3713D is designed for charging various lead-acid batteries, including WET, MF, GEL, AGM, Ca/Ca, and Start/Stop types. Thanks to support for 6V, 12V, and 24V batteries, this charger is suitable for a wide range of vehicles and applications.

Powerful performance

With a maximum charging current of 37A and three adjustable charging currents (5.5A, 11A, and 22A), the FL 3713D offers flexibility for charging batteries with capacities ranging from 30Ah to 450Ah. The advanced multi-step charging technology and the "I-U" charging characteristic (constant current-constant voltage) ensure an efficient and fast charging cycle.

Advanced desulfation function

A notable feature of the FL 3713D is the regeneration program for sulfated batteries. This program helps restore deeply discharged or sulfated batteries, which can significantly extend battery life.

Comprehensive safety features

The charger is equipped with various protections to safeguard both the user and the vehicle electronics:

• Reverse polarity protection
• Short-circuit protection
• Overvoltage protection
• Spark-free operation

In addition, the charger can be connected directly to the vehicle's electrical system without disconnecting the battery, saving time and effort.

Maintenance mode for long-term use

Thanks to the "Floating" function, the FL 3713D can remain permanently connected to the battery. This ensures that the battery is always fully charged and ready for use, ideal for vehicles that are stationary for extended periods.
