I went with AGM's because I didn't want to worry about water
levels and other lead acid maintenance
issues. However, I'm a perfect candidate for AGM's because my boat
sits in a slip on shore power
every time I come back from sailing. So they stay charged up all the time, which is important for their health
. That said, I have a set of LifeLine's that are stickly house batteries I bought before the 2013 season. They're going great, stay on the boat
all winter and are ready to go in Spring.
