Measuring 160 × 90 × 161 mm, it is the direct replacement for motorcycles fitted from the factory with a 20 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 YB16BA-YB16BA2 is for The Motobatt YB16BA-YB16BA2 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 5.90 kg. ### The Motobatt YB16BA-YB16BA2: Quadflex range and AGM technology Within the Motobatt catalogue, the **Quadflex** series groups the references designed for this use. The YB16BA-YB16BA2 is the 20 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. ### Dimensions, polarity and mounting In terms of format, the Motobatt YB16BA-YB16BA2 measures 160 × 90 × 161 mm (length × width × height) and weighs 5.90 kg. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters. ### Motobatt: the maker behind the YB16BA-YB16BA2 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. All the Motobatt batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### How to make it last longer If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. 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. ### Official warranty The Motobatt YB16BA-YB16BA2 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 Orders placed **before [[ks:cutoff]]** with the battery in stock ship the same day.

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 YB16BA-YB16BA2 battery last? Expected lifespan of the Motobatt YB16BA-YB16BA2 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 YB16BA-YB16BA2 model? Dimensions (length × width × height) are 160×90×161 mm — also written as 160x90x161 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 YB16BA-YB16BA2 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 YB16BA-YB16BA2 fits 4 verified vehicle versions in our database. ### Which batteries are equivalent to the Motobatt YB16BA-YB16BA2? 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. ## Compatible vehicles This battery fits 4 vehicles.
