Seems odd as some vehicle charging systems run at 13.8v while others run at 14.4v, you'd expect a fit and replace option of lithium batteries not have issues. Especially as the batteries I have seen are supposed to be direct replacement.
This may be why some people have had a fit and forget, and others have replaced lithiums more often than oil. Maybe it depends on the bike more than anyone would like to admit.
