    Given how incompetent they have proved to be, and after waiting 11 days for them to sort out a problem without them having done anything, I cannot under any circumstances recommend that anyone makes a purchase on their website.

    I think Varta is top-notch.

    I've been using this brand for years and it's never let me down, although I've used many others without having any complaints either.

    Choose the right replacement for your car

    Before fitting the VARTA B20, check the 207 × 175 × 190 mm space, positive terminal position, connections and hold-down as well as the 45Ah capacity and 400A starting current. The same car model may require different batteries depending on engine, year and equipment. Fuel type or engine displacement alone does not establish compatibility.

    Capacity and starting current are different ratings

    The 45Ah rating is nominal capacity; 400A describes cold cranking current. When comparing 45Ah car batteries, check technology and dimensions too: similar or higher capacity does not automatically make a battery suitable.

    Replacement, charging and maintenance

    Vehicles with a battery management system may require battery registration or adaptation using diagnostic equipment after replacement. Use a charger suitable for the battery voltage and technology and follow the battery and vehicle instructions. Consult a qualified professional if the installation or configuration is uncertain.

    Price, availability and online ordering

    Check the VARTA B20 price, current availability and buying options on this page. The order total, delivery charges and available shipping options are confirmed in the basket before you place the order. Published product reviews can help you assess other buyers’ experiences, but they do not establish compatibility with your particular car.

    Questions before buying

    Which VARTA B20 battery am I buying?

    Part number B20 identifies this 12V, 45Ah, 400A battery measuring 207 × 175 × 190 mm. Capacity and starting current are separate ratings.

    Are matching dimensions enough?

    No. Required technology, voltage, polarity, terminals and mounting must also match, with suitable electrical ratings. Do not downgrade an AGM or EFB technology required by the vehicle.

    How do I check polarity?

    Positive terminal on the left. Check the terminal positions on the actual battery and their orientation in the vehicle; do not rotate the battery to compensate for cables that do not reach.

    If searching for VARTA Black Dynamic B20, use part number B20 and its specifications to identify the replacement. VARTA has brought its former conventional Silver Dynamic, Blue Dynamic and Black Dynamic ranges together as Dynamic SLI. A new range name does not change a conventional battery into AGM or EFB.
