We carry premium-quality batteries equivalent to or better than the vehicle manufacturer's originals, compatible with every Harley-Davidson model. Varta, Tudor and Exide are the main OEM brands for European vehicles. Select your specific model to see exact references and dimensions.
Yes. We sell premium-quality batteries equivalent to or better than the vehicle manufacturer's original: same or higher technical specifications (capacity, cold-cranking amps, technology, dimensions and polarity). Varta is OEM supplier to the main European car makers — most Harley-Davidson cars leave the factory with a Varta.
Motorcycles can use GEL, AGM, or conventional batteries. GEL batteries are ideal for occasional use. AGM batteries are the best option for heavy use or high-power motorcycles. Always check the polarity before installation.
Polarity indicates which side has the positive (+) terminal. This is critical for motorcycles because some models have the positive terminal on the left and others on the right. Check the label on your current battery or the manufacturer's manual.
Yes. First disconnect the negative (−) wire and then the positive (+) wire. When installing the new one, connect the positive (+) wire first and then the negative (−) wire. Always respect the correct polarity.
Use the search tool by selecting your vehicle's make and model. Our system automatically filters compatible part numbers verified by our technicians. If you have any questions, contact us via WhatsApp.
