All YUASA YT series "Liquifix" batteries use AGM technology which consists of an Absorbent Glass-fibre Matting between the lead plates inside the battery. This material absorbs and stabilises the electrolyte so the battery can be mounted in any orientation and also allows higher discharge rates without causing internal damage to the battery. AGM batteries are often referred to as “Gel” batteries because the electrolyte appears to be solid but they are also sometimes known as “Dry” or “Sealed” batteries.

CAUTION: Please be aware that if this battery is mounted on its side or at more than 30 degrees from vertical in your bike then you must leave it to stand in an upright position after you have filled it for at least 24 hours before you install it.

Do you supply this battery pre-filled?
While these are sealed maintenance free batteries, they actually come as a two part kit so you need to fill the battery prior to installation; once filled the battery is sealed maintenance free for life. The reason they are supplied like this rather than pre-filled is simply to extend the shelf life and ensure there is no deterioration in the battery prior to installation.
