Is that for new builds only, or would it also apply to swapping an AGM battery to lithium ![Huh? ???](http://www.myswag.org/Smileys/classic/huh.gif)
that legislation was actually introduced in July last year.
all manufacturers were given a 12 months grace period.
it is *not* retrospective. (so if you're upgrading from deep cycle to lithium you should be ok)
