Livio Hearing Aid Charger Desiccant

Hi! I’m new to the world of hearing aids and need some help.

I have a pair of Starkey Lucio rechargeable hearing aids. There is a desiccant puck in the lid.

Where I can I find more? I don’t see any on Starkey’s website, but I do have an email into then asking.

Also, I heard one can microwave the puck? My question is how long can I put it in thr microwave for to dry it out.

Many thanks.
