Yuasa MF YTZ10 S YTZ10S

The Yuasa YTZ10S is a sealed, maintenance-free AGM motorcycle battery supplied in the popular Z-series case size used by many sports and road bikes. As a non-spillable design, it needs no electrolyte top-ups over its service life and can be mounted without the venting hassles of a conventional flooded battery.

It suits riders replacing a factory-fitted YTZ10S and anyone after a straightforward, no-fuss replacement from a long-established battery brand. Check your existing battery's part number, terminal layout and tray dimensions before ordering.

• Maintenance-free design — no electrolyte topping up required
• Sealed, non-spillable AGM (absorbed glass mat) construction
• YTZ10S case size and terminal layout for direct replacement fitment
• Yuasa-branded motorcycle battery

Check the battery's state of charge before first fitting and charge it if required — installing an undercharged battery shortens its life.
Use a charger designed for sealed AGM/maintenance-free batteries; do not use an unregulated or high-current automotive charger.
Do not attempt to open the battery or add water or electrolyte — the case is sealed and must stay that way.
Disconnect the negative terminal first when removing, and reconnect it last when fitting, to avoid shorting against the frame.
Tighten terminal bolts firmly but do not overtighten, and keep the terminals clean, dry and free of corrosion.
Secure the battery in its tray so it cannot move or vibrate against surrounding components.
If the bike is stored or ridden only occasionally, keep the battery on a suitable maintenance charger or top it up periodically — leaving it flat for long periods causes permanent damage.
Store spare or off-season batteries in a cool, dry place away from direct heat and sunlight.
Recycle the old battery through a battery collection point; do not place it in general waste.
