Professional Dual Purpose EFB

For Highest starting performance and Essential energy demands.

Lower-spec boats and motorhomes still need the right product to perform at their best. That’s why we’ve developed VARTA® Professional Dual Purpose batteries. Long-lasting and maintenance-free, they’re ideal for seasonal use. Boats and motorhomes with moderate energy demands still need the right product to perform at their best. The Dual-Purpose range, based on EFB technology enables a higher cycle life arobustness against partial state of charge usage. This is suitable to supply power for short trips, like an off-grid weekend with medium equipment, like lighting and phone chargers. It is ideal for dual purpose applications (starting and overall energy supply) and provides up to twice the cyclic stability of conventional flooded batteries. Furthermore, the minimal self discharge makes them ideal for seasonal use. Engineered in Germany, the VARTA® Professional Dual Purpose batteries use the patented PowerFrame® grid for reliable starting power, fast recharge and corrosion resistance.

Got a question?

  • The VARTA® Partner Portal provides partner workshops with assistance in this decision, with battery positions, battery selections and installation instructions for almost all vehicles which are in use in Europe.

    For end customers, the VARTA® Battery Search is an ideal tool to find the right battery.

  • Extending your battery's lifespan involves a few key practices:

    1. Disconnect cables: Always disconnect the negative terminal first to prevent short circuits, then disconnect the positive terminal.
    2. Check battery's state: For non-maintenance-free lead-acid batteries, visit a professional. For maintenance-free batteries, clean vent pipes and avoid checking electrolyte levels.
    3. Start charging: Keep the battery upright if removing from the car. Turn off electrical consumers before connecting the charger. Connect the red cable to positive terminal first, then the black cable to negative terminal.
    4. Stop charging: Switch off charger when fully charged. Disconnect cables starting with the red cable from positive terminal, then the black cable from negative terminal.

  • Extended periods of inadequate storage conditions can lead to deep discharge, causing irreversible damage to the battery.

    Hence, it's crucial to ensure the battery is stored in suitable locations and at appropriate temperatures.
