I have extra batteries (14500, 18650, CR 123A) for all my devices and plenty of charging slots on my multi-function chargers. My question is, after they are completely charged, if I'm not going to be using them for a day or two, is it best to leave them on the charger until I need them or take them out once they are charged? Or does it matter? Thanks in advance!

Li-Ion's Left In Chargers Cause House Fires
best to take them out as soon as the green light goes on, Li-Ion's cannot stand over-charging, and most cheapo chargers don't terminate properly, so you end up relying on the cells protection circuit to stop the battery from over-charging, not the best thing to do,
of course if you have a Pila charger and each cell is protected you can leave them in because that charger turns off when it's done, and will only start charging if they've been on the charger long enough to drop a bit...

Also if you are going to store them for a longer period you want to drain about 20% or 30% prior to storage. There is a battery sticky that will give you more detail.
