It measures 200 × 130 × 163 mm, the format sought by anyone replacing a 33 Ah battery in motorcycles. - Same JIS code as the original battery: fits first time. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Energetic cranking for high-compression engines. - Resistant to the vibration typical of two wheels. ### What the Motobatt YHD12H is for The Motobatt YHD12H is a common replacement in motorcycles, scooters, quads and personal watercraft. If your bike spends the winter standing, a trickle charger stops it reaching spring flat. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 10.80 kg. ### The Motobatt YHD12H: Quadflex range and AGM technology The YHD12H is part of the Motobatt **Quadflex** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery. ### Will it fit your current battery tray? In terms of format, the Motobatt YHD12H measures 200 × 130 × 163 mm (length × width × height) and weighs 10.80 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### What Motobatt does differently Motobatt is the motorcycle battery specialist with Quadflex technology: four terminals that let you connect the battery in any position and a sealed AGM construction ready to fit. All the Motobatt batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Usage and maintenance tips Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. ### Official warranty The Motobatt YHD12H comes with the **manufacturer's official warranty**. The warranty does not cover discharge through prolonged inactivity: if the bike stands for months, use a trickle charger. ### When you get it and how to return it Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### How is the Motobatt YHD12H 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 long does the Motobatt YHD12H battery last? Expected lifespan of the Motobatt YHD12H is 4 to 7 years in regular use (depends on technology and climate). 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 Motobatt YHD12H battery? Dimensions (length × width × height) are 200×130×163 mm — also written as 200x130x163 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. ### Is the YHD12H 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 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The YHD12H typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the YHD12H model? 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. ## Reviews - **Average rating**: 4.67 / 5 (9 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 · 2026-10-05*
