It replaces the original battery in cars with the 225 Γ— 174 Γ— 217 mm format without any modifications: the same 84 Ah capacity and the same terminal layout (positive on the right). - 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. - Direct replacement for the original battery in cars without Start-Stop. - Reliable cold starting thanks to its high cranking current. ### Applications of the Varta 084011039 battery The Varta 084011039 covers the needs of cars with conventional starting, without a Start-Stop system, with 84 Ah of capacity and a construction built for that use. ### Format and fitting of the Varta 084011039 In terms of format, the Varta 084011039 measures 225 Γ— 174 Γ— 217 mm (length Γ— width Γ— height). 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. For the swap to be direct, the space your current battery occupies must match those three dimensions and the same terminal layout; otherwise you will need adapters or the hold-down will have to change. ### The Varta 084011039 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. This series uses lead-acid technology with plates optimised for a good balance between cranking power and service life. It is the natural replacement when your car has no Start-Stop and came with a standard battery from new: the same philosophy, without paying over the odds for a chemistry you do not need. ### Why choose a Varta battery When a workshop recommends Varta, it is not down to marketing: it is one of the brands with the lowest return rates in the sector, with application coverage spanning practically the entire European fleet, from the city car to the commercial vehicle. Varta batteries are made under the Clarios group with German technology and quality controls that make them one of the best-selling choices in Europe. As a lead battery, it is 100% recyclable through any collection point. Varta's production combines automated lines with verification of more than 100 parameters per unit; that traceability is what underpins its reputation for reliable starting throughout the battery's life. ### Manufacturer's warranty The Varta 084011039 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. ### Technical sheet Download the official technical sheet for this battery with all the manufacturer data.

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’). ### How long does the Varta 084011039 battery last? Expected lifespan of the Varta 084011039 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 084011039 model? Dimensions (length Γ— width Γ— height) are 225Γ—174Γ—217 mm β€” also written as 225x174x217 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 084011039 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. ### Will the Varta 084011039 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 16:30–18:00 (Spanish time, CET)). The 084011039 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the 084011039 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· 2026-11-03*
