Check in seconds by entering your **registration** in our finder. ### Format and fitting of the Varta YTX9 Its external dimensions are 151 × 87 × 106 mm. The positive terminal on the left determines which side the cables end up on: it is the detail behind most mistaken purchases, so it is worth checking before ordering. It uses a B00 hold-down, the system that anchors it to the vehicle's battery tray. Before replacing it, measure the space your current battery sits in: if it matches on all three dimensions and on the terminal layout, the swap is direct and needs no adapters. ### The Varta YTX9 and the Powersports AGM Active range The **Powersports AGM Active** series is Varta's AGM line for motorcycles that arrives activated and charged from the outset: it fits straight on, with no acid to add and no charging before use. It combines the robustness of AGM (resistance to vibration and to deep discharge) with maximum ease of installation. In the new portfolio it also absorbs the former high-performance versions (AGM High Performance), so it covers everything from general use to large-capacity, custom and trail bikes with heavy starting demands. On two wheels, vibration and extreme temperatures take a heavy toll on the battery. This range reinforces the internal plate mounting and seals the unit to withstand that use, delivering the instant burst of cranking power a motorbike or quad engine needs after weeks standing idle. *This battery used to belong to Varta's **Powersports AGM High Performance** range; following the brand's change of commercial naming (2025), it forms part of the new **Powersports AGM Active** 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 been supplying the assembly lines of the leading car groups for decades. Replacing with a Varta is, in practice, giving the vehicle back the battery its manufacturer intended. 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. More than 100 manufacturing parameters are checked on every Varta battery before it leaves the plant, a level of rigour that explains why so many workshops and manufacturers trust the brand as their first-choice replacement. ### Manufacturer's warranty The Varta YTX9 battery comes with **a 6-month official warranty** from the manufacturer. ### Care and maintenance If the bike goes unused for long spells, a trickle charger greatly extends the battery's life and prevents sulphation. Storing it somewhere dry and checking the terminals at the start of each season helps it start first time. Motorcycle batteries suffer in the cold and when left idle: in winter, a maintenance charger stops the battery from discharging completely. With this care, it will typically deliver well over several years of service. ### Technical sheet Download the official technical sheet for this battery with all the manufacturer data.

What does this technology offer? Yes. The YTX9(FA) 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 motorcycles with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### How do I check that the Varta YTX9(FA) 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 YTX9(FA); 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 YTX9(FA) battery installed in the vehicle? In most motorcycles 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 motorcycles 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 YTX9(FA) motorcycle model cover? This motorcycle battery includes 6 months of official manufacturer warranty against manufacturing defects. It is normal that warranty is shorter on bikes, jet skis and quads: the use pattern (with prolonged standstills) accelerates the battery's natural sulfation. Practical tip: connect a trickle charger if the bike will be idle for more than 2 weeks — it dramatically extends battery life. ### How long does Varta YTX9(FA) 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. ### How do I return the YTX9(FA) 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. ### Where can I buy the Varta YTX9(FA) 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 YTX9(FA) model? Expected lifespan of the Varta YTX9(FA) is 5 to 8 years in mild-climate motorcycle 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 YTX9(FA) battery? Dimensions (length × width × height) are 151×87×106 mm — also written as 151x87x106 mm — following the European DIN standard. Always measure the space in your motorcycle 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 3 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 Ah and CCA does this battery have? Nominal capacity 8 Ah[?cca: and [cold-cranking amps 135 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 motorcycle? 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 YTX9(FA) fits 116 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 motorcycles. See the "Equivalents" section to view recommended options at the same performance level. ### Is this battery a better choice than another equivalent? 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 YTX9(FA) battery?
