Getting the best from the Fulmen FK820
Delivery vans in town stop and restart hundreds of times between depot and last drop. Check whether the battery sits in the boot and needs a vent tube. A dashboard warning about the start-stop system often points to the battery.

Care tips for AGM batteries
Nothing sloshes around in a glass-mat battery, because every drop of acid is held in the separators. Motorcycles benefit from glass-mat batteries because they tolerate lean angles and vibration. Too much voltage makes the valves vent gas that can never be replaced.
