DEFA workshop chargersPowerful workshop charger

.
Conserves the battery and supplies consumers during work such as software updates, diagnostics, battery replacement or ECU programming.
Our recommendation for charging starter batteries in the automotive workshop.

Features

  • Perfect for updates and other power-consuming work.

    This charger protects the vehicle's electronics during battery changes and power-consuming activities such as software updates. It can also recondition deeply discharged batteries.

    Your advantage: Customer electronics settings are retained and charging times are shortened or even eliminated.

  • Practical and uncomplicated

    Thanks to its compact design, detachable cables and clever mountings, the charger can be easily attached in almost any work situation. In addition, the device is protected against dust udn Eidnringen of foreign objects.

    Your advantage: Powerful function without distracting from your work.

  • Versatile

    Thanks to the intelligent technology, all lead-acid batteries used in the automotive sector and, with the DEFA Workshop 35A 2.0, also lithium batteries are charged safely and reliably.

    Your advantage: Charge all vehicles in your workshop with one type of charger.

Characteristics

  • User-friendly and fully automatic high-frequency charger.
  • 7-phase charger with permanent trickle charge as well as analysis before and after charging and reactivation mode for deeply discharged batteries.
  • 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 and also for start-stop batteries, both Enhanced Flooded Batteries (EFB) and AGM batteries.
  • DEFA Workshop 35A 2.0 also suitable for lithium batteries.
  • Protection against reverse polarity, contact spark and short circuit. With galvanic isolation and temperature-compensated charging.
  • DEFA Workshop 35A 2.0 also protected against ingress of foreign bodies > 1mm (IP40).
  • Supplies connected loads with 13.7 volts thanks to power supply function.
  • Rubberised hook for attachment to the bonnet, workstation or workshop trolley. Wall bracket for storing the charger with practical cable holder.
  • DEFA-WS-35 with detachable 5 m cable.
  • Charging status can be read off via LED. Error indication via flashing light.

Charger Knowledge

Cleanliness pays off
To ensure proper battery function, it makes sense to keep the battery surface clean and dry. Greasy or silicone-containing dirt on the lid can hinder the flow of current. Moisture on the battery can cause a short circuit in the worst case.
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 …
How does a charger work?
In principle, the charger reverses the chemical process that provides the current output in the charged battery. To do this, it provides the battery with voltage (in volts) and current (in amps). The charge controller in the charger decides how much current …
Transformer charger versus high-frequency charger
Transformer chargers with a downstream rectifier are relatively inexpensive, but they are large, heavy and less efficient than high-frequency chargers. They allow 1- to 3-step charging methods based on the W-characteristic (W, Wa, WaPuls, W0Wa, WU, WUWa …
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 …
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 …
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, …
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 …
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 …
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 …
