How do you open an AGM to put acid in?
They come in one of two configurations (NOTE this applies to Sealed wet as well)
one has a screw in vent/cap with a snap in top cap
The other just has a snap in (But not out) cover
In both cases the top cover is designed to snap in once the fluid is added, but not to be removed ever.. Barbed snap.
And again, very common.. Batteries age very very very slowly, if at all, when they sit DRY on the store shelf.
Once the liquid is added and the acid hits the lead.. The clock starts. Shelf life can destroy the battery before it is sold.. So they ship them dry.
