I have been playing for a while now and I have never known how to recharge an enchanted weapon. I know in Oblivion you could use Varla Stones to recharge your weapons, but what can you use in Skyrim (if you can recharge weapons that is)?

Filled Soul Gems. Only way to recharge weapons.

Just go to weapon in the inventory, press T(PC)/R2(PS3)/RB(360), pick a filled soul gem in your inventory, and voila! Recharged!

The http://www.uesp.net/wiki/Main_Page is your friend for these sorts of things.

you use a Soul Gem. go in your inventory, hover over a Soul Gem with a soul in it, and press recharge

Thanks everybody! I hardly use enchanted weapons but this will come in handy when I decide to .
