The positive terminal on the right determines which side the cables run to: it is the detail that causes the most buying mistakes, so it is worth checking before ordering. It uses a B13 hold-down and a type 1 terminal, the system that anchors it to the vehicle's battery tray. For the swap to be direct, the space your current battery occupies must respect those three dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will have to change. ### The Varta N70 and the Dynamic EFB range The **Dynamic EFB** range (silver label) uses EFB technology, an enhanced lead-acid design for entry-level Start-Stop systems and vehicles with high energy demand. It withstands far more cycling than a conventional battery. It is the correct replacement for cars that came with EFB from the factory and a solid step up from a standard battery. It sits one rung below AGM in terms of cycling demand. In a modern vehicle the battery powers ever more electronics even with the engine switched off. This series is sized for that draw and for restarting the engine dozens of times a day without losing performance, something a traditional starter battery cannot handle. *This battery used to belong to Varta's **Blue Dynamic EFB** range; following the brand's commercial renaming (2025), it forms part of the new **Dynamic EFB** series.* ### 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 an application coverage spanning practically the whole European vehicle parc, from the city car to the industrial vehicle. 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 makers cannot always assure. ### Manufacturer's warranty The Varta N70 battery comes with **a 2-year official warranty** from the manufacturer. ### Care and maintenance In a vehicle with Start-Stop the battery works far 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 stays in calibration. To get the best from it, avoid very short journeys, which stop it recharging after each start. Keeping the terminals clean and the hold-down secure prevents vibration-related faults in the engine bay. ### Technical sheet Download the official technical sheet for this battery with all the manufacturer data. [Download technical sheet (PDF)](/fichastecnicas/data-sheet-battery-varta-n70-70ah-760a-12v-en.pdf) ## Frequently asked questions ### Is the Varta N70 an EFB battery? When is EFB used? Yes. The N70 is an EFB (Enhanced Flooded Battery): flooded lead-acid reinforced with plate additives. Withstands more cycles than a conventional but fewer than an AGM. Fitted to cars with basic Start-Stop (no regenerative braking). More affordable than an equivalent AGM, lifespan 4-6 years. ### Is the N70 model suitable for Start-Stop cars? Yes. As EFB technology it is designed for Start-Stop vehicles. EFB batteries cover basic Start-Stop (no regenerative braking). 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 do I check that the Varta N70 battery fits my vehicle? Three ways: 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 for the N70; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 9:00–18:00 CET). ### How is the Varta N70 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. ### What is the warranty period of this battery? We provide 2 years of official manufacturer warranty against manufacturing defects. It applies to defects such as damaged cells, internal short-circuits or abnormal capacity loss. Wear from misuse (prolonged overcharging, wrong charger or faulty alternator) is not covered. If the battery fails, we replace it at no cost after a technical inspection. ### What is the delivery time for this battery? In mainland Spain and Portugal it arrives in 24 h if you order before 17:00 and the battery is in stock — it leaves the same day and arrives the next business day. Afternoon or weekend orders ship the next business day. For Balearics, Canaries and other EU destinations, allow 2-5 days. Shipping cost is calculated in the cart based on destination and service (standard, express, cash on delivery). Tracking number is sent by email + SMS as soon as the parcel ships. ### How do I return the N70 model if it doesn't fit? Yes. You have 14 days from delivery to return it. In mainland Spain and Portugal returns are FREE — we cover the return shipping cost via prepaid label. In other EU countries the return shipping cost is the customer's. It must arrive in its original packaging with no signs of installation. If it was defective, the warranty covers replacement even after the 14-day period. ### How much does the Varta N70 battery cost? The current price at baterias.com is 116,80 € (VAT included; 96,53 € excl. VAT), updated every 24 hours. The applicable VAT may vary with the destination country and is confirmed in the cart. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery). ### Where can I buy the Varta N70 battery? At baterias.com — authorised distributor with real stock, 24h delivery in mainland Spain and Portugal if you order before 17:00, and full manufacturer warranty. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery). Secure payment by card, Bizum, PayPal or bank transfer. If you choose at-home installation, our technician will take the used battery and dispose of it through an authorised collection point. ### What is the service life of the N70 model? Expected lifespan of the Varta N70 is 4 to 6 years in basic Start-Stop car use. 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 N70 model? 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. ### How many kilos does this battery weigh? It weighs 18,8 kg. Most of the weight is lead. If you plan to fit it yourself, use gloves and a carrying strap (AGM batteries are slightly heavier than conventional due to the absorbent glass-mat fibre). ### What is the capacity and CCA of the N70 model? Nominal capacity 70 Ah[?cca: and [cold-cranking amps 760 A]] at 12 V. Ah measure the total energy available (autonomy); CCA (also written A in cold or EN under the European standard) measure the instantaneous power to crank the starter motor. A battery with more CCA starts better in winter; one with more Ah keeps accessories on for longer. ### Will the Varta N70 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 9:00–18:00 CET). The N70 fits 492 verified vehicle versions in our database. ### 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. ### Which is better: Varta N70 or an alternative from another brand? This battery and its equivalents from Bosch, Tudor or Exide are technically comparable: same dimensions, same voltage and same capacity. The differences are warranty (Varta and Bosch: 2 years; Tudor and Exide: 2 years on the equivalent line), manufacturing plant (Varta and Bosch share origin in the Clarios Group; Tudor and Exide belong to Exide Technologies) and price. For private use any of these brands will give 4-6 years of life. Compare them in the "Equivalents" section. ### What do users say about the Varta N70 battery? The average rating of the Varta N70 on baterias.com is 4.73/5 from 108 verified customer reviews. The product rating, when available, is shown on the product page next to the stars. You can also check our public Trustpilot profile at shop level (4.5/5 from 11,443+ verified reviews). Most-praised points: reliable cold start, lifespan above 5 years and fast delivery; most common complaints mention BMS-equipped cars that need OBD registration after fitting. ### What exactly is an EFB battery like the Varta N70? An EFB (Enhanced Flooded Battery) is a flooded lead-acid battery reinforced with plate additives (carbon and polyethylene) and thicker grids. It withstands twice the cycles of a conventional battery and handles deep discharges better, but less than an AGM. It is the original fitment on cars with basic Start-Stop (no regenerative braking): Renault Energy TCe, Peugeot/Citroën PureTech, Fiat MultiAir, Hyundai/Kia ISG, Ford EcoBoost. If your car came with EFB from the factory, this is the correct battery — upgrading to AGM is optional (marginal improvement). If it came with AGM, EFB may fall short: better fit AGM. The Varta N70 is original and meets EN 50342-6. ### Is there anything to do after replacing a Start-Stop battery? 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 N70 ships factory-charged at 80-90% so you can use it straight after fitting. ## Compatible vehicles This battery fits 492 vehicles.
