Model: 12/24V 15A - Charge for batteries from 30Ah to 330Ah, maintenance for 30Ah to 500Ah batteries
The new cutting edge electronic HF battery chargers revolutionise the way of charging batteries.
Designed to charge all types of lead batteries, conventional batteries and batteries of the latest generation, they are
particularly suited to withstand extensive charging cycles, even throughout an entire season, for example. For the whole
time in which the vehicle or watercraft is not used but the battery needs to be constantly monitored and its charge held,
the battery charger can be left connected without the risk of damage.
Devised for the vehicle industry, they can also be used in other fields such as sports and leisure. They can be used, for
example, for motorcycles, scooters, sports cars, vintage cars, snow mobiles, lawnmower tractors and so on. They also
find specific use in the field of commercial and farming vehicles, watercraft and mobile homes.
They are ideal for all types of Wet cell lead batteries, with liquid electrolyte, or Dry cell lead batteries, with immobilized
electrolyte (for example, sealed batteries type Gel, Agm and Mf).
All the charging parameters are set using charge function keys on the control panel. Based on the specific model
purchased, you can set:
- the battery voltage (12 or 24 Volt)
- the type of battery (WET cells or sealed GEL-type with immobilized electrolyte, or AGM)
- the work cycle to be carried out (normal charge, deep recovery charge, power supply unit as substitute for the
battery)
The battery chargers are also equipped with display LED and acoustic indicators, which trigger alarms if the polarity is
reversed, if the battery is faulty and if the voltage is incorrect.
They are made of insulating material and can be wall-mounted. They have a high level of protection against external
agents and are safeguarded against overheating and short-circuiting, they are equipped with clamps.
CHARGE CYCLES
The charge cycles of the new HF battery chargers have been developed especially to optimize the charge of all types of
batteries currently on the market. The numerous constructional technologies of batteries currently commercialized (Dry,
Gel,Wet, Agm) require different charging curves to ensure correct and complete charging. The HF battery chargers
extend the life of your batteries because they ensure the proper charge for each specific battery.
The control and fulfilment of the charge cycle is managed by a microprocessor. The battery chargers of the HF series
have specific charge cycles based on the type of battery to be charged (Wet, Gel or Agm). Each charge cycle is
implemented in six phases: two diagnosis phases and four charge phases (pursuant to standard DIN 41772) (Fig.
2 - 3 - 4).
• First diagnosis phase of the state
of the battery: "A1"
• First charging phase:
"Very low recovery"
• For GEL and AGM batteries: "R1"
• For WET batteries: "R2"
• Second charging phase: "I"
• Third charging phase: "U0"
• Fourth charging phase: "R3"
"Recovery" *
• Second diagnosis phase of the
state of the battery: "A2"
• Fifth charging phase: "U"
• Sixth charging phase: "Up"
• * Recovery function: this charging mode is used to recover Wet 12 or 24 Volt batteries that have been left unused
for a long time and in which the acid has stratified. This function acts physically on the battery's electrolyte solution so
that it mixes again and contrasts stratification.

The battery charger analyses the charged state of the battery to be
charged.
For GEL and AGM batteries: if the battery is very low, the battery charger
will start to charge with a soft current charge until the battery reaches the
optimal voltage to be able to start the second charging phase.
For WET batteries: if the battery is very low, the battery charger will start
to charge using a pulsating current until the battery reaches the optimal
levels of voltage and current to be able to start the second charging
phase.
The battery is charged at a constant current until it reaches its maximum
voltage.
The battery is charged at a stabilised voltage until the current reaches
minimum values.
Only for battery chargers set on WET: the battery is charged deeply at
a constant current and increasing voltage to boost the charge capacity
of the battery.
The battery charger analyses the state of efficiency of the charged
battery.
The battery is held at a reduced constant voltage. (for 48 hours).
The battery is held with pulses of current (constantly running).
