It is a go-to option when you need a **Fiat battery**, a Case one or any other model built around this same format. The compatibility list also includes models from Zetor, Same, Case International, Lamborghini, Steyr, Hurlimann, Volvo and Bolinders - Volvo. ### Size and fitting of the Varta M9 The Varta M9 is made in the 513 × 223 × 223 mm format and weighs 45,1 kg. The positive terminal on the left 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 B03 hold-down and a type 1 terminal, the system that anchors it to the vehicle's battery tray. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### The Varta M9 and the ProMotive SLI range The **ProMotive SLI** range is Varta's starter line for industrial vehicles — lorries, buses and machinery — which in the new portfolio unifies the former ProMotive HD (Heavy Duty) and SHD (Super Heavy Duty). It offers a high cranking current for large-capacity diesel engines and a reinforced construction. Its reinforced grids and separators cope with the vibration and cycling of long-distance haulage and of the most severe use, aiming for maximum service life and starting reliability in fleets that work long hours. Compared with a passenger-car battery, this range is calibrated for severe, continuous use: greater mechanical strength and more tolerance of cycling and of the knocks of the road. It is the correct replacement for a lorry, bus or machine putting in long days. *This battery used to belong to Varta's **ProMotive HD** or **ProMotive SHD** range; following the brand's commercial renaming (2025), it forms part of the new **ProMotive SLI** series.* ### Why choose a Varta battery Varta is an original equipment (OEM) supplier to a good share of Europe's car manufacturers: many cars leave the factory with a Varta fitted. Buying a replacement means, in most cases, refitting the original battery with the same quality and the brand's official warranty. 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 M9 battery comes with **a 1-year official warranty** from the manufacturer. One important warning for industrial vehicles: most lorries carry **two batteries wired in series** (a 24 V installation). If you replace only one, the new battery ends up working alongside the old one — which has already lost capacity and has higher internal resistance; that imbalance leaves one overcharged and the other short, shortens the life of the new unit, and the manufacturer may treat it as misuse and **void the warranty**. That is why it is always advisable to change **both batteries at the same time**. ### Care and maintenance In professional use, checking the state of charge and the battery hold-down regularly prevents breakdowns on the road. Vibration and the high temperatures of the engine bay are the factors that shorten its life the most, so secure mounting is key. Keeping the terminals clean and tight and checking the charging system extends battery life in vehicles that clock up long hours. A well-maintained battery reduces the risk of downtime caused by a no-start. ### Technical sheet Download the official technical sheet for this battery with all the manufacturer data. [Download technical sheet (PDF)](/fichastecnicas/data-sheet-battery-varta-m9-170ah-1000a-12v-en.pdf) ## Frequently asked questions ### How do I check that the Varta M9 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 M9; 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 M9 battery installed in the vehicle? In most trucks 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 trucks with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### What is the official warranty period of this truck battery? This battery includes 1 year of official manufacturer warranty against manufacturing defects. It covers internal electrical failures and abnormal capacity drops. It does NOT cover misuse (sulfation from heavy duty without proper recharge, alternator overcharge, etc.). On confirmed defect after technical inspection, we replace the M9 at no cost. ### How long does Varta M9 delivery take? 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. ### Can I return the Varta M9 battery if it doesn't fit or doesn't work? 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. ### What is the price of the M9 model? The current price at baterias.com is 263,99 € (VAT included; 218,17 € 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 M9 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 M9 model? Expected lifespan of the Varta M9 is 4 to 6 years in regular truck 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 dimensions of the Varta M9 battery? Dimensions (length × width × height) are 513×223×223 mm — also written as 513x223x223 mm — following the European DIN standard. Always measure the space in your truck before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### How much does the Varta M9 battery weigh? It weighs 41,1 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). ### How many amps does the Varta M9 battery have? Nominal capacity 170 Ah[?cca: and [cold-cranking amps 1000 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. ### Is the M9 valid for my vehicle? 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 M9 fits 494 verified vehicle versions in our database. ### Which batteries are equivalent to the Varta M9? 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 trucks. See the "Equivalents" section to view recommended options at the same performance level. ### Is the M9 model better than its equivalents from other brands? 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 reviews does the M9 model have?
