Measuring 278 × 175 × 190 mm and with the positive terminal on the right, it is the direct replacement for cars fitted from the factory with a 70 Ah battery in this format. - Built for the intensive cycling of the Start-Stop system. - Keeps the vehicle's electronic management correctly calibrated. - Reinforced resistance to the partial charging and discharging of daily use. - A higher guaranteed number of starts than a conventional battery. ### Applications of the Varta E39 battery The Varta E39 covers the needs of cars with a Start-Stop system and high electrical demand with 70 Ah of capacity and a construction built for that use. Check that it matches your current battery in dimensions, terminals and hold-down: this reference weighs 20,4 kg and has terminal 1 and a B13 hold-down. ### Format and fitting of the Varta E39 The Varta E39 is made in the 278 × 175 × 190 mm format and weighs 20,4 kg. The positive terminal on the right determines which side the cables end up on: it is the detail that causes the most buying mistakes, so it is worth checking before you order. It uses a B13 hold-down and terminal 1, the system that anchors it to the vehicle's battery tray. For the swap to be direct, the space taken by your current battery must respect those three dimensions and the same terminal layout; otherwise adapters would be needed or the hold-down would change. ### The Varta E39 and the Dynamic AGM range The **Dynamic AGM** range (gold label) is Varta's flagship for cars: AGM technology, with the electrolyte absorbed into glass fibre, designed for the most advanced Start-Stop systems and for braking energy recovery. It withstands thousands of charge and discharge cycles without losing performance and is the only correct choice when the car came with AGM as standard. Ideal for vehicles with high electrical consumption and very frequent starts. AGM (absorbed electrolyte) and EFB (enhanced lead) technologies are designed for the extra work of Start-Stop and energy recovery. Replacing a battery of this type with an equivalent one is essential: if the car called for AGM, it must have AGM so the electronic management stays calibrated. *This battery used to belong to Varta's **Silver Dynamic AGM** range; following the brand's commercial renaming (2025), it forms part of the new **Dynamic AGM** series.* ### Why choose a Varta battery Choosing Varta means sticking with the reference the car manufacturer itself approved in the first place. Against own-brand batteries, the difference is not in the purchase price but in how many winters the battery lasts before leaving you stranded. 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 is Europe's leading maker of starter batteries: its production volume and quality controls guarantee consistent reliability batch after batch, something own-brand makes cannot always promise. ### Manufacturer's warranty The Varta E39 battery comes with the **official manufacturer warranty**. ### Care and maintenance In a vehicle with Start-Stop the battery works much harder, so it pays to drive far enough for it to recharge and to always replace it with the same type (AGM for AGM, EFB for EFB) so the electronic management is not thrown out of calibration. To get the best from it, avoid overly short journeys, which prevent it from recharging after each start. Keeping the terminals clean and the hold-down secure prevents faults caused by vibration in the engine bay. ### Technical sheet Download the official technical sheet for this battery with all the manufacturer data.

Yes. The E39 from Varta uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for cars with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### Is the Varta E39 battery suitable for Start-Stop? Yes. As AGM technology it is designed for Start-Stop vehicles. AGM batteries support advanced Start-Stop and regenerative braking thanks to their higher cycle count. EFB is recommended for basic Start-Stop; AGM is recommended when regenerative braking is also present, thanks to its higher cycle capability. It works straight out of the box — on most modern vehicles registering the battery via OBD is recommended so the alternator automatically applies the optimal charging profile. ### How is the Varta E39 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 this page. 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 (−) 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 — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). 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 E39 battery last? Expected lifespan of the Varta E39 is 5 to 8 years in mild-climate car use with 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 dimensions of the Varta E39 battery? Dimensions (length × width × height) are 278×175×190 mm — also written as 278x175x190 mm and correspond to the European L3 case size — 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. ### Will the Varta E39 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 — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The E39 typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which interchangeable batteries are there for this one? 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 — 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. ### When do I need an AGM battery like this one? AGM (Absorbent Glass Mat) technology uses absorbent fibreglass that retains the electrolyte, eliminating leaks and allowing up to 3× more charge/discharge cycles than a conventional battery. It is the recommended option when the car has advanced Start-Stop with regenerative braking (BMW EfficientDynamics, Mercedes Eco, Audi MHEV, Land Rover ECO, Volvo i-Stop). Withstands tilted positions, high vibration and extreme temperatures better than EFB. The Varta E39 is fully original and meets European EN 50342-6 standards for advanced Start-Stop. ### Will my car recognise the new battery automatically? On most cars it is not strictly necessary — the alternator detects the new battery and adapts the charge automatically. It is recommended to register the battery via OBD so that the alternator applies the optimal charging profile from the first minute and extends the battery life as much as possible (especially on brands with sophisticated BMS: BMW, Mercedes, Audi, Volvo, Land Rover). Any workshop with an OBD scanner (~10-15 € labour) does it in 5 minutes. DIY apps: VCDS / Carista (VAG), Bimmercode (BMW), iCarsoft. If you do not register, the car will still start correctly — the alternator just takes a few days to adjust the profile. The Varta E39 ships factory-charged at 80-90% so you can use it straight after fitting. ## Equivalent batteries - [VARTA LFD75](https://baterias.com/gb/battery-varta-lfd75-12v-75ah-650a) ## Reviews - **Average rating**: 4.83 / 5 (209 reviews) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-03*
