Care tips for AGM batteries
Many glass-mat designs tolerate sideways mounting, as long as the maker says so. Motorcycles benefit from glass-mat batteries because they tolerate lean angles and vibration. Over winter, a smart unit set to its AGM programme keeps a glass-mat battery healthy with no effort.
Other options with identical dimensions
If you prefer another make, these fit the same space with the same terminal side.

Getting the best from the Varta 518919031
First sunny weekend of spring, and the bike that sat under a cover all winter just clicks. Use a low-amp maintainer designed for small batteries, not a big car charger. Overfilling a dry battery with acid causes spills and corrosion.
