Oticon Sensei Pro shuts down after startup

My one hearing aid has started to have this issue recently. I replaced the battery and it turned on, but after a few seconds, it turns off while making the sound like that of a low battery. Then when I tried to turn them off and on again, they didn’t make the startup jingle and just 3 beeps and that’s it. Can someone help me with this problem? Or should I just go to a hearing aid station?

I found the following online. I hope it’s helpful. I also found that an accidental activation of Airplane Mode might cause similar symptoms. And, if possible, make sure the contact surfaces of the battery and of the battery door are clean and dry.

Troubleshooting Steps:

  1. Check the battery: Replace the battery with a fresh one and ensure it’s properly installed.
  2. Clean the hearing aid: Use the provided brush to clean the microphone and receiver openings.
  3. Check for moisture: Ensure the hearing aid is dry and free from moisture.
  4. Reset the hearing aid: Turn the hearing aid off and on again (usually by opening and closing the battery door).
  5. Update firmware: Check for firmware updates through the Oticon ON app.
  6. Consult your audiologist: If the problem persists, consult with your audiologist or hearing care professional for further assistance.

Edited to add: Dead or very low battery is said to be a cause of the 3 beeps. Are your batteries stored properly and not yet at the expiration date? If they’re zinc-air batteries, have you allowed adequate activation time before inserting the battery into the hearing aid?I

Activate as @Zebras advises. Be careful about how spares are stored and carried, too, because I’ve read that affects battery life.
I have rechargeable (Phonak Infinio 50R), but I did research rechargeable battery vs replaceable battery HAs before my 1st audiologist appointment for a hearing test, just in case. I’ve been reading this forum a lot, too.

I have taken another battery and did as recommended by @Zebras. Still the same result, it turns off for a little and then goes out.
I store my batteries in my room on a shelf, in packs of six in the original box and packaging they came from.

I had taken a battery from a different six pack, did as instructed and it works normally, i think. Possibly my previous battery pack has something wrong with it? I will change the six packs and see if anything changes when I have to change the battery again. Thank you all so much.!

Even tho it’s working now. Do leave the batteries for 2 minutes before inserting into the hearing aid as you’ll find your batteries last longer doing this.

I even saw an article recommending 5 minutes to realllly be sure activation is maximized. It also said it results in up to 80% longer battery life. And it had a reminder to always open the battery door when not wearing the . I suspect that the author of the article has experienced 45 seconds seeming like 2 minutes, and 2 minutes seeming like 5 minutes!

I also remove sticker from battery, then vigorously rub the battery head on a piece of cloth to remove any sticky residue, then let it sit for 5 min or so, and then insert in aid.

I remove batteries from aids at night so there’s no contact with the aids to drain the batts. That’s been my working protocol for 35 yrs. :slightly_smiling_face:

It’s definitely something with the batteries, after the initial fix, everything went back to turning off after several seconds. Even when I did as recommended, they had a very little runtime(?) Only of about an hour, my batteries usually lasted me a few weeks so this is highly unusual. I’ll go out to buy a different pack of batteries to see of it changes anything.

Well I did have a similar experience with my audi! We are in a very humid area, and even tho her clinic is cold as an iceberg, she literally went thru TWO 8-packs of batteries trying to get a working ONE to put in my 312 aid when it came back from repair. Each and every battery the sticker just about slipped off. It’s like the humidity did a number on them - even tho they were hermetically sealed in the pack! She’d remove the sticker, rub the battery top, wait 2 min, and I’d get 10-60 seconds of use before the battery was dead.

We invented cuss words! Invoked curses on the battery maker. And then - sheepishly - I recalled that I kept a spare pair on me, so we swapped one in and voila! Problem solved.

My audi said SO FEW folks use batts anymore that her supply sits in moist, cold storage for months. Not what I wanted to hear having invested in 2 pairs of 312s. Dodo calling! :dodo:

A place that is running cold could still have humidity problems.
A lot of times that’s a sign of misapplied ac systems.

If anything, anywhere near your battery storage area is magnetic, or generates a magnetic field, I’d recommend storing the batteries elsewhere. And, if the place you bought them uses a magnet to clear a shoplifting alarm, or has a magnet embedded in the checkout counter for that purpose, the entire number of batteries you got there may be screwed.

Edit to add: @Manowarrrrrs - see if you can find a hearing aid battery tester, or consider investigating whether they make rechargeable versions of your batteries! The tester can prove whether the battery is good, once activated. Then you’ll have info on bad battery vs HA malfunction.

I have been traveling to visit family so I order my batteries online. When they arrive I’ll store them elsewhere. I’ll see about getting a tester but I might have to travel again soon so I’ll see if it arrives soon enough.

Sometimes the hearing aid could be defective. You might give your audiologist a call to problem solve this. When something odd like this happens, my audiologist sends the hearing aid to the company and they either repair or replace with new hearing aids

Tried a completely new pack of batteries today, still the same result, it’s definitely something with the hearing aid. I’m going to find an audiologist in the city and address the problem there.
