I just crafted some Daedric war axes, with extra effect Frost and Shock. I enchanted each with a Grand Soul Gem. I decided I'd go try them out on some of the folks hanging around Whiterun.

You can read the number of charges on the weapon when you look at them in your inventory.

Its always a trade off when enchanting your weapons like this, do you want to have more uses so you do not have to charge them up so often or do you want the enchantments to be more effective.
Hope this helps.
The following factors affect the soul gem charge of weapons:
