Measuring 151 × 87 × 110 mm, it is the direct replacement for motorcycles fitted from the factory with a 11 Ah battery of this format. - Holds its charge through winter storage. - Compact and lightweight format. - AGM: faster recharging and better cycle resistance than a conventional battery. - Sealed and ready to fit, no acid handling. ### What the Motobatt YTZ14S-YTZ12S is for Designed for motorcycles, scooters, quads and personal watercraft, the Motobatt YTZ14S-YTZ12S replaces the original battery of bikes that use this code or format. Check the position of the positive terminal before ordering. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 3.50 kg. ### Size, terminals and hold-down of the Motobatt YTZ14S-YTZ12S The Motobatt YTZ14S-YTZ12S is made in the 151 × 87 × 110 mm format and weighs 3.50 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 batteries stand out for capacity and cranking current above the original battery in the same tray, thanks to a compact AGM design and the four-terminal Quadflex system. We guarantee that every Motobatt arrives new, charged and with the manufacturer's full warranty. ### The Motobatt YTZ14S-YTZ12S: Quadflex range and AGM technology The YTZ14S-YTZ12S 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. In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery. ### Care and maintenance Avoid repeated cranking attempts on a cold bike for long: if it does not start on the third try, let the battery rest for a minute. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. ### Warranty and coverage The Motobatt YTZ14S-YTZ12S 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 Order **before [[ks:cutoff]]** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **[[ks:return_days]] days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### How is the Motobatt YTZ14S-YTZ12S 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 our blog. 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. ### What is the service life of the YTZ14S-YTZ12S model? Expected lifespan of the Motobatt YTZ14S-YTZ12S 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 measurements of the YTZ14S-YTZ12S model? Dimensions (length × width × height) are 151×87×110 mm — also written as 151x87x110 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. ### 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 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The YTZ14S-YTZ12S typically fits a wide range of European vehicles thanks to its standard DIN case format. ### Which batteries are equivalent to the Motobatt YTZ14S-YTZ12S? 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. ## Equivalent batteries - [VARTA 509901020](https://baterias.com/gb/battery-varta-motorcycle-12v-9ah-ytz12s-4-509901020) - [VARTA 511902023](https://baterias.com/gb/battery-varta-motorcycle-12v-11ah-ytz14s-4-511902023) - [EXIDE ETZ14-BS](https://baterias.com/gb/battery-exide-etz14-bs-12v-11ah-205a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-20*
