• Holds its charge through winter storage.
• Sealed and ready to fit, no acid handling.
• AGM: faster recharging and better cycle resistance than a conventional battery.

What the Motobatt YT12BBS-YT12B4 is for

Designed for motorcycles, scooters, quads and personal watercraft, the Motobatt YT12BBS-YT12B4 replaces the original battery of bikes that use this code or format. Check the position of the positive terminal before ordering. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 3.52 kg.

Dimensions, polarity and mounting

The Motobatt YT12BBS-YT12B4 is made in the 150 × 70 × 130 mm format and weighs 3.52 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.

Motobatt: the maker behind the YT12BBS-YT12B4

Motobatt is the motorcycle battery specialist with Quadflex technology: four terminals that let you connect the battery in any position and a sealed AGM construction ready to fit. All the Motobatt batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

The Motobatt YT12BBS-YT12B4: Quadflex range and AGM technology

Within the Motobatt catalogue, the Quadflex series groups the references designed for this use. The YT12BBS-YT12B4 is the 11 Ah model of that family, with the same performance as its siblings in other sizes.

AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.

Usage and maintenance tips

Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight. 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.

Warranty and coverage

The Motobatt YT12BBS-YT12B4 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.
