It replaces the original battery with no modifications in lorries using the 278 × 175 × 190 mm format: the same 66 Ah capacity and the same terminal layout (positive on the right). - Tolerance of the vibration of thousands of kilometres on the road. - High cranking current for large-displacement diesel engines. - Reliability through repeated starts and while powering cab equipment. - Reinforced grids and casing for the harsh demands of haulage. ### Vehicles compatible with the Varta D33 battery This battery is listed as compatible with more than 53 vehicles from manufacturers such as Carraro, Belarus, Antonio Carraro, Atlas, John Deere and Huerlimann. For anyone who needs to change the **battery in their Carraro** or Belarus, this Varta D33 reproduces the original specifications. Added to that list are models from Fendt, Sullair, Case, Büscher, Clayson, Hinomoto, RAMmax and Ama. ### Format and fitting of the Varta D33 The Varta D33 is made in the 278 × 175 × 190 mm format and weighs 16,80 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. Checking the three dimensions and the terminal position before buying avoids the most common error when replacing a battery. ### The Varta D33 and the ProMotive SLI range The **ProMotive SLI** series is Varta's starter line for professional transport, bringing the former ProMotive HD and SHD together under a single name. It is built to crank large-displacement diesel engines and to take the daily punishment of the lorry, the bus and construction machinery. The key to this range is sheer sturdiness: reinforced plates and fixings that stand up to thousands of kilometres of vibration and to deep discharge cycles, keeping fleet downtime from starting failures to a minimum. A commercial vehicle demands a high cranking current and endurance against the vibration of thousands of kilometres. This series uses reinforced grids and rugged construction to cope with repeated starts of large diesel engines and with the draw of auxiliary cab equipment. *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 A good share of the vehicles on Europe's roads left the factory with a Varta fitted: the brand has spent decades supplying the assembly lines of the leading car groups. Replacing with Varta means, in practice, giving the vehicle back the battery the manufacturer had in mind. 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 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 D33 battery comes with **a 1-year official warranty** from the manufacturer. One important warning for commercial vehicles: most lorries carry **two batteries connected 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 means one is overcharged while the other falls short, it 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, periodically checking the state of charge and the battery hold-down prevents breakdowns out on the road. Vibration and the high temperatures of the engine bay are the factors that shorten its life 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 stoppages caused by a failure to 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-d33-66ah-510a-12v-en.pdf) ## Frequently asked questions ### How do I check that the Varta D33 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 D33; 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 D33 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. ### How many months of warranty does the D33 truck model cover? 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 D33 at no cost. ### When will I receive the D33 model? 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 D33 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. ### Where can I buy the Varta D33 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 D33 model? Expected lifespan of the Varta D33 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 measurements of the D33 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 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 D33 battery weigh? It weighs 15,8 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). ### How many amps does the Varta D33 battery have? Nominal capacity 66 Ah[?cca: and [cold-cranking amps 510 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. ### Does this battery fit my truck? 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 D33 fits 53 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 trucks. See the "Equivalents" section to view recommended options at the same performance level. ### Is the D33 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 do users say about the Varta D33 battery?
