I’m planning on using my KS9s( just serviced)as backups for Philips 9050. Wondering if I should use them regularly or is it safe to only use when needed. Since these use a battery and my use pattern its good for 5 days should I use for the 5 days?
Anything else?

Use only when required, just as long as you keep the battery doors open, or better still remove the batteries. Also keep your aids in a dry location.

I wear my backup aids, Real1s, at least one day each month to exercise the batteries. I have done this with my Oticon rechargeable aids this way for 4 or 5 years now. And never had a failure of my backup aids being ready to use.

Thanks for all the replies, I’m going to establish a use the backups note in my calendar so I remember to use them.

I do not, I charge them then power them off an put them in the carrying case that came with them. I keep a schedule and wear them on day a month then charge them overnight then power them off for another month or until I need them.

Unless you would be unable to wait for a charge, I would think that the partial discharge state from a day of use might be ideal for storage. Power them off and store like that. Then charge it up before the use day the following month? I’m not sure this would actually extend the battery life as at some point it is on the margin. Have you tried both approaches?

I’ve been using a pair of Lumity rechargeables for more than a year now. Recently, been thinking about getting another pair of Lumity aids with replaceable (312…??) batteries as a back up pair to use on occassions when there isn’t time to charge up the rechargeables. Also, it seems almost all the audiologists in my area are pushing rechargeables; so it sounds like a good idea to get a pair of battery aids, as a long term backup. I understand the replaceable battery aids can be kept as backups for quite a long time. But my present audi is against the idea. He thinks I should wait a little longer to get the Phonak Spheres & then keep my present rechargeables (post servicing), as backups.

I have allowed my backup aids to be stored up to two months and was still able to get a full days usage out of the batteries that were charged that 2 months ago.
It depends on the health of the batteries and how hard the aids are working. I wrear as my primary aids th Oticon INTENT1, i stream audiobooks and from my TV adapter on average 4 hours a day. My aids are good for 22 hours on a single charge. My backup aids are the Real1 aids and under similar conditions my aids last 21 hours even after being stored for a month.

I personally think disposable battery are the best as backup aids, as you don’t need to do anything once you remove the batteries. Nothing will degrade if left in a cool dry place. I have 6 working pairs (4x Marvel, 1x Paradise and 1x Lumity), and they all work as like brand new when I put some batteries in. Rechargeables will need a little more care.
