• 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.
