How do you recharge them in the oven? Times and temperatures?
I also have a large one that says "do not recharge' or something to that effect, is that bs or can I still stick it in an oven to remove the absorbed moisture?
I know this isn't completely gun related, but I put these in my ammo boxes to help keep down the humidity content.
TIA

In my professional experience most bag type dessicators can be recharged 3 times before they are useless. This is in reference to the blue colored indicating dessicant. You can tell the desiccant has absorbed moisture once it has turned from blue to pink. Once the dessicant turns black after recharging (300 degrees fahrenheit for 3 hours in a conventional oven) then it needs to be replaced. .

Many bag type dessicators have a warning on them not to recharge as heating them in an oven will cause the seams of the package they are in to open. This seems to apply to some of the new bag type dessicators.

The instructions on my dessicant packs say to use a 200 degree oven for 3 or 4 hours. In my experience, that has worked fine, but needs to be done pretty much every week (I live in the SF Bay area of California).
