Dryer for Phonak P90r

In June, the VA issued me a pair of Phonak P90s with size 13 batteries. They have been very satisfactory and, as I have done for years, I use a dryer daily.

Now, in order to get some more features, I am getting Phonak P90s that are rechargeable. These have lithium batteries. I’m looking for a dryer that will not damage them. The VA will provide dessicant but I would rather have a dryer. Please tell me a dryer solution that will not damage the Phonaks. Thank you.

Phonak Charge and Care is a dryer/charger. I paid $155

Perfect DryLUX is one of the best dryers available; they run about $40 at Costco.


IMO, most rechargeables, and the Phonak P90 in particular, really don’t need a dryer. That model has a Liquid Ingress Protection rating of 8 which means “Immersion, in 1 meter (3 ft 3 in) or more depth for at least 30 minutes with no harmful effects.” I have the Costco KS-10.0Ts which are basically identical to Audeo Paradise P90RTs and figure if they can withstand drowning for a half-hour or more, a little sweat isn’t going to faze them.


I haven’t used my PerfectDryLuxe since I got rechargeable aids, and won’t to keep from damaging the batteries.

I liked when I was using it that the UV lamp sanitized the domes, and the heat would dry any moisture and wax on the domes, making it easier to wipe or brush off.

As @Fender_Bender said, - the P90r shouldn’t need drying out in normal use. However since my Phonak charger has a space in the lid for a silica gel capsule, I place one in there since I have some - just in case.
Roughly every month I dry the capsules out briefly in the microwave and reuse. It is probably unnecessary but there is no cost involved and very little hassle.


Picked up a pair of KS 10’s yesterday and musing on whether a dryer is needed. I have a Phonak drying cup (kind you pop a desiccant tablet at the bottom) which I used with my old HAs. Presumably no harm to the rechargeable batteries? Just wanted to check before I do something daft…

I have the KS10T hearing aids and use the PerfectDry Lux drier every night after recharging the HA’s. I do this mainly to sanitize them. Prior to these aids I had the Rexton 42’s that I also got from Costco. I suffered from itchy ear every day with the Rexton’s and had several ear infections. I have had the KS10T’s about 7 months and since using the UV drier I do not have itchy ear or have I had an ear infection. I also turn off the HA’s prior to drying them. I don’t know if this is necessary but that is what I was told by the installer at Costco. The jury is still out on whether they need to be turned off or not.
