The Motobatt YB16BA-YB16BA2 motorcycle battery is rated at 12 V, 20 Ah and 240 A of cold cranking current (EN) from the Quadflex range, and is designed for motorcycles, scooters, quads and personal watercraft. 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.

Frequently asked questions
How is the Motobatt YB16BA-YB16BA2 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.
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.
