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 Rex 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.
As they are consumable items, car batteries have a 2-year warranty, truck batteries a 1-year warranty, and all others (motorcycle batteries, cyclic batteries, etc.) a 6-month warranty. If a battery has a manufacturing defect, it will be replaced at no cost to the user.
Under normal circumstances, batteries usually arrive within 1 to 2 days of ordering. However, there are some cases where delivery may take a little longer: peak seasons (Black Friday, Christmas, etc.), palletized shipments, occasional stock shortages, etc.
