Just stumbled across this thread . . . fwiw, Olson just published a youtube review of this charger wherein (at 5:00) he cites its dehydrator capability as an important feature since, in his opinion, moisture is a chief cause for HA’s repairs. Apparently, even in hot and dry climes (like AZ), some people sweat a lot.
Since I already have the (common) Zephyr brick dehydrator I used with my previous battery HA’s, my (since fired) Audi recommended I periodically use it with my new rechargeables. That was bad advice, as the manufacturer’s website indicates that the Zephyr and similar models produce too much heat, possibly damaging the recharageable battery. This manufacturer instead recommends its DryBoost UV dehydrator (in which you place your standard charger, the cycles run in parallel).
But Oticon on its Smart Charger web page suggests the PerfectDry LUX system as a safe alternative, which is only ~$60 and only uses a 30 minute cycle. So if one doesn’t need the extra power-bank on this charger but wants dehydration, this appears to be a good alternative.
