With dimensions of 133 × 90 × 142 mm and the positive terminal on the right, it is the direct replacement for motorcycles fitted from the factory with a 10 Ah battery in this format. - Direct replacement for the original motorbike, scooter or quad battery. - Construction built to withstand the vibration typical of two-wheelers. - Performs well in the cold and after periods of inactivity. - High cranking peak in a compact, lightweight format. ### Applications of the Varta YB10L battery Designed for motorcycles, scooters, quads and personal watercraft, the Varta YB10L is a direct replacement when you need its same 10 Ah capacity and format. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a B00 hold-down. ### Format and fitting of the Varta YB10L In terms of format, the Varta YB10L measures 133 × 90 × 142 mm (length × width × height). The positive terminal on the right determines which side the cables run to: it is the detail that causes the most buying mistakes, so it is worth checking before ordering. It uses a B00 hold-down, the system that secures it to the vehicle's battery tray. Checking the three dimensions and the terminal positions before buying avoids the most common mistake when replacing a battery. ### The Varta YB10L and the Powersports AGM Active range The **Powersports AGM Active** range consists of AGM motorcycle batteries activated and charged at the factory, ready to fit. They combine the toughness of AGM technology with the convenience of immediate installation. They are aimed at general motorcycle and scooter use, with reliable starting and no maintenance from day one. Unlike a car battery, what matters here is power density in a minimal size and resistance to vibration. It is the direct substitute for the original motorcycle battery, with the advantage of reliable starting even in the cold and after periods of inactivity. *This battery used to belong to Varta's **Powersports AGM High Performance** range; following the brand's change of commercial naming (2025), it now forms part of the new **Powersports AGM Active** series.* ### Why choose a Varta battery Varta is an original equipment (OEM) supplier to a good share of Europe's car manufacturers: many cars leave the factory with a Varta fitted. Buying a replacement means, in most cases, refitting the original battery with the same quality and the brand's official warranty. 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. 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 YB10L battery comes with the **official manufacturer warranty**. ### 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.

Yes: the YB10L from Varta uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. It withstands more cycles than a conventional battery and copes better with heat. ### How should this motorcycle battery be charged? With a 12 V motorcycle charger delivering at most 10 % of its capacity: 1 A for its 10 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger. ### Does it need maintenance? No: being AGM, it is sealed and nothing needs topping up. Just keep it charged if the bike stands for a long time. ### How many years does this battery last? There is no exact figure: for a battery such as the Varta YB10L (AGM), a reasonable guide is 4 to 6 years, keeping it charged when the bike is not in use. 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 are the measurements of the YB10L model? It measures 133×90×142 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. ### Which side is the positive terminal on this battery? It has the positive on the right (polarity). It must match your current battery: reversed polarity means lengthening cables or reconfiguring the system, with a risk of short circuit. Put it in front of you, terminals towards you: the post with the red ring and the + sign is the positive. ### Does this 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)). In every case, the motorcycle manufacturer's specifications (owner's handbook) take precedence. ### What are the equivalents of the YB10L model? A battery interchangeable with the Varta YB10L must match it on dimensions (133×90×142 mm), polarity (positive on the right), capacity (10 Ah) and cranking current (120 A). See the "Equivalents" section of this page for the recommended options at the same performance level. ## 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 · 2026-11-12*
