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 4.40 kg. ### Dimensions, polarity and mounting It has external dimensions of 151 × 87 × 130 mm and weighs 4.40 kg. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change. ### Why choose Motobatt batteries 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 YTX12BS: Quadflex range and AGM technology Within the Motobatt catalogue, the **Quadflex** series groups the references designed for this use. The YTX12BS is the 14 Ah model of that family, with the same performance as its siblings in other sizes. 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. ### Usage and maintenance tips If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight. ### Official warranty The Motobatt YTX12BS 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 6:00 pm** with stock available and it leaves today: mainland Spain and Portugal receive it in 1 to 2 working days, the islands and the rest of the EU in 1 to 5 days. You have **14 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 should this motorcycle battery be charged? With a 12 V motorcycle charger delivering at most 10 % of its capacity: 1.4 A for its 14 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger. ### What is the service life of the YB12BB2 model? Estimated lifespan of the Motobatt YB12BB2: 3 to 5 years, keeping it charged when the bike is not in use. Treat it as an approximate guide, as every case is different. It can vary considerably with usage (short or long journeys), temperature, the condition of the alternator and charging system, power drawn with the engine off and maintenance. Cold demands more at every start and intense heat evaporates the electrolyte. ### What size is this battery? Check the room available in your motorcycle, because a single millimetre too much can stop the clamp from closing. Its dimensions are 151×87×130 mm, also written 151x87x130 mm; the height already includes the terminals. ### Will the Motobatt YB12BB2 battery fit my motorcycle? Not sure? Try your number plate in the finder (DGT/DVLA/KBA detect model and engine) or the "Compatible vehicles" tab, checked by our technical team; if your motorcycle is not there, send us make, model, engine and year on WhatsApp and we will reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). Always cross-check with what the motorcycle manufacturer states in the owner's handbook. ### What are the equivalents of the YB12BB2 model? A battery interchangeable with the Motobatt YB12BB2 must match it on dimensions (151×87×130 mm), polarity, capacity (14 Ah) and cranking current (200 A). The options at the same level are in the "Equivalents" section of this page. ## 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 · 2026-11-14*
