On my motorcycle, I only use AGMs because the vibration kills the flooded lead acid ones. AGMs will last close to 5 years where FLA last one year max in my application
As with any battery, keep them fully charged at all times. Most batteries fail because of owner neglect.
I use Odyssey on my motorcycle. The FLAs I used were Yuasa.
I have 2 Odysseys on my boat.
For both my boat and motorcycle, I use a Odyssey recommended charger.
