got mine on friday, perfect fit for 808 65mm batteries, also when a regular 510 is put in it the light on bat comes on as well so it might just be an all around charger, though it wont close down over megas or longer 808s and shorter 510s would need a spacer to hold down, so that doesnt make much sense. But like i said Perfect fit for 65mm 808s which my g/f just got a kit for early last week...thanks again myvaporstore
