Can this battery be mounted on it's side?
Yes you can mount this battery on it's side however if this battery is mounted 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.
