DEFA showroom chargersDiscreet at the dealership

.
With its power-supply function, the charger supplies the consumers during demonstrations, fittings and inspections and gently keeps the battery fully charged.
Our recommendation for charging starter batteries in the car dealership.

Features

  • Perfect for demonstrations

    In the showroom, the battery is particularly challenged: Lighting and electronics are activated every time the doors are opened, but the engine and alternator cannot charge the battery. This charger is designed exactly for this use and keeps all functions active and battery charged without overloading the battery.

    Your advantage: Your vehicles are always ready for test drives and sales without battery replacement.

  • Unobtrusive

    The compact design, detachable cables and clever mountings allow the charger to be placed almost invisibly under the vehicle or even in the engine compartment.

    Your advantage: powerful function without distracting from the object on display.

  • Versatile

    Thanks to the intelligent technology, all lead-acid batteries used in the automotive sector and, with the DEFA ShowroomCharger 50A, also lithium batteries are charged safely and reliably.

    Your advantage: Charge all vehicles in your exhibition or collection with one type of charger.

Characteristics

  • User-friendly and fully automatic high-frequency charger.
  • 7-phase charger with trickle charging over an unlimited period of time as well as analysis before and after charging.
  • Suitable for flooded 12-volt starter batteries including calcium batteries also with 14.7-volt charge voltage, for sealed AGM, GEL, MF and SLA batteries as well as for start-stop batteries, both Enhanced Flooded Batteries (EFB) and AGM batteries.
  • DEFA ShowroomCharger 50A also suitable for lithium batteries.
  • Protection against reverse polarity, contact spark and short circuit. With galvanic isolation.
  • Discreet. Made of black anodised aluminium and noiseless.
  • Invisible placement. Removable cables can be routed through the engine compartment.
  • Charge status readable via LED. Error indication via flashing light.
  • Software update possible via micro USB interface.

AGM or GEL drive batteries
Drive batteries in AGM or GEL technology are sealed, absolutely maintenance-free, leak-proof batteries in a closed design with a fixed electrolyte (in fleece or gel). Both are suitable for medium to heavy cyclic use, for example in cleaning machines, …
What does that even mean? Charging curve?
Current and voltage during charging can be measured and displayed as a curve over the course of the charging time. Depending on which processes, controls by switch-off (a) or switch-over points (0) are possible with a charger, one speaks of the provided charging characteristics.
Safety instructions for handling acid
Battery acid consists partly of sulphuric acid, which is highly corrosive. It attacks your skin, textiles and even metal. Put on protective clothing! So always wear gloves, safety glasses and possibly an acid-proof apron when handling batteries. Choose …
Batteries without vent hose
Only conventional, wet batteries need a vent hose, because they gas strongly during operation. The resulting steam can escape through the openings in the plugs. To prevent the vapour from damaging the vehicle, conventional batteries are vented to the …
Chargers for rescue and safety vehicles
Emergency and rescue vehicles and other safety-related types of vehicles often sit around for months, but when it comes down to it, they need to be ready at a moment's notice to put out fires, rescue injured people or clear roads. Chargers like the Fronius …
Why is the charging voltage of the charger important?
In principle, when charging, the electrons within the battery move from one electrode to the other, in the opposite direction to when they draw current, i.e. discharge. If a discharged battery is provided with too high a voltage from the current or voltage …
Chargers for supply batteries
In order to supply the connected consumers permanently, supply batteries usually have a larger capacity than starter batteries, which are intended to deliver a lot of power, especially in the short term. Chargers designed for starter batteries reach their …
Charging correctly step by step
Tip: For full performance: Charge before first installation! 1. preparation Check that your charger matches the battery. Does the charger support the correct charging voltage? Does the charging current provided match the battery? What charging curve …
Checking the battery step by step
There are many reasons for weakening or failing batteries. An important step in tracking them down is to measure the voltage with a battery tester. Here's how: 1. preparation Disconnect the battery from the vehicle, if possible remove it. Tips on how …
Which charger for which battery type?
The most important distinction is that sealed batteries and especially lithium batteries can react extremely to the heat and overpressure during overcharging. A reliable cut-off is particularly important here. Modern fully automatic electronic chargers …
