It replaces the original battery in cars with the 177 Γ— 175 Γ— 185 mm format without any modifications: the same 66 Ah capacity and the same terminal layout (positive on the right). - Direct replacement for the original battery in cars without Start-Stop. - Reliable cold starting thanks to its high cranking current. - Long service life with normal use and a charging system in good order. - Maintenance-free lead-acid technology: no need to top up the water. ### Applications of the Varta 066017036 battery With 66 Ah, the Varta 066017036 is sized for cars with conventional starting, without a Start-Stop system, as a direct replacement for the original battery. ### Format and fitting of the Varta 066017036 The Varta 066017036 is made in the 177 Γ— 175 Γ— 185 mm format. The positive terminal on the right determines which side the cables sit on: it is the detail that causes the most buying mistakes, so it is worth checking before you order. Checking the three dimensions and the terminal positions before buying avoids the most common mistake when replacing a battery. ### The Varta 066017036 and the Classic range The **Classic** range is Varta's most affordable series, using traditional lead-acid for older vehicles and straightforward applications. It puts reliable starting at the lowest cost first. It is the basic option when no special performance or cycling resistance is called for: an affordable, direct replacement with Varta's manufacturing backing. Compared with an EFB or AGM Start-Stop battery, this range prioritises a keen price and punchy starting in conventional cars. With proper care β€” avoiding deep discharges and keeping an eye on the alternator β€” a battery in this series gives several years of trouble-free service. ### Why choose a Varta battery Choosing Varta means going with the reference the car manufacturer itself signed off in the first place. Against own-brand batteries, the difference is not the purchase price but how many winters the battery lasts before it leaves you stranded. Behind Varta is Clarios, one of the largest manufacturers of starter batteries in the world and a supplier to the assembly lines of numerous car brands. That German engineering heritage translates into reliable starting year after year. Varta is Europe's leading manufacturer of starter batteries: its production volume and quality controls guarantee consistent reliability batch after batch, something own-brand labels cannot always promise. ### Manufacturer's warranty The Varta 066017036 battery comes with the **official manufacturer warranty**. ### Care and maintenance To get the most out of it, keep the alternator in good condition and avoid leaving lights or accessories switched on with the engine off. Repeated very short journeys are its main enemy: they stop the battery from recharging fully and shorten its life. If the car is going to stand for weeks, it is worth disconnecting the terminal or using a trickle charger so that it does not fall below the safe charge threshold. Making sure the terminals are clean and properly tightened also helps it start reliably. ## Frequently asked questions ### How is the Varta 066017036 battery installed in the vehicle? In most cars it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (βˆ’) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation β€” with positive on the right match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). On cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Varta 066017036 battery last? Expected lifespan of the Varta 066017036 is 4 to 6 years in regular car use without Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured. ### What are the measurements of the 066017036 model? Dimensions (length Γ— width Γ— height) are 177Γ—175Γ—185 mm β€” also written as 177x175x185 mm β€” following the European DIN standard. Always measure the space in your car before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### What polarity does the Varta 066017036 battery have? Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk. ### Does this battery fit my car? Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year β€” we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The 066017036 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the 066017036 model? Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology β€” an EFB cannot be replaced with a conventional battery in Start-Stop cars. See the "Equivalents" section to view recommended options at the same performance level. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” automotive battery specialists since 2012. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-26*
