I didn't find this in the article, so:

You can "recharge" silical gel by baking in the oven at 120 C for a couple of hours. If you do, be careful to remove the casing before you do, unless it is heat safe.

I have a small collection of oven safe dessicant packs that I keep on hand for emergency drying electronics.

This sounds like a great idea, but how do you keep it from being "drained" or hydrated?

If they're not getting hydrated slowly, they're not serving any purpose. The whole point is that water goes into them instead of whatever you're trying to keep dry.

I think the grandparent comment meant keeping unhydrated during storage (for future uses of emergency drying electronics), not while it is being actively used for its intended purpose.
