If it's an automatic battery (no button) then you should not drip because the
juice could go through the atty and into the drag sensor hole in the battery and kill it.
If you really mean "dripping"
If you have manual battery that seems sealed pretty well on the end, to do "dripping" you would either use an 801 drip tip on the atty and drip through that. Or you could use a cart with no stuffing - remove cart, drip on the little /\ looking atomizer bridge, replace empty cart and vape it. 2-3 drops to start, then 1-2 as needed.
If you actually mean filling the cart (a real cart, not an empty dummy that may have come stuck on the atty) - there is stuffing in the cart. I think with an 801 cart, on the inside the stuffing should be visible. You drip
juice on the stuffing until it looks moist but not a puddle.
But I don't have an 801 - I have a 901. Some ecigs have atties that stick INTO the cart (rather than cart sticking into the atty). When a cart has a recessed
juice cup you usually have to push it up for filling by sticking an unbent paperclip in the mouth-hole. Many super-mini carts work with way, fewer mini carts.
