Most days the left hearing aid emerges from overnight charging only half charged, so I start the day one-eared.
But on this forum I have read plenty of identical complaints about the same thing and still no action from the manufacturer. What can I do?
I would say that I monitored this forum closely for issues with Oticon rechargeable batteries, and while yes, there have been complaints about Oticon batteries not lasting the whole day for people, or have reduced full-day capacity sooner than the expected 3 year warranty, that is different than your description of your issue here, which is that the charger doesn’t complete a full charge on your left aid by morning time (only half charge). Your issue description is very specific and is totally different than the usual failure to provide a full-day capacity in less than the 3 year warranty.
Actually, I don’t recall any complaint about Oticon battery charging issue that is identical to what you’re reporting → failure to completely charge overnight in one of the aids. If you do have specific links to forum threads/posts that complained about your EXACT same issue, please share with us so we can review them more closely.
I’m also puzzled why it would stop charging at 50%, then in another hour or two, it finished charging the remaining 50%. I presume that you must have removed the partially charged left aid out of the charger, to find out that it’s not fully charged yet, then put it back in for another hour or 2 for the charge to complete. Is that the correct assumption?
You said that you must have made Oticon resolve the issue for you about 6 times in 2 years. So does that mean that they resolved the issue for you but each time only lasts on the average of about 4 months before the issue returns again? So it worked for a good several months before it broke, then the pattern repeats itself? Or did you actually spend a lot of time living with your workaround before you turn it in for repair?
If it’s always the same left aid that exhibited the problem, did you at any time (after a few failures) insist on Oticon giving you a brand new left aid replacement to eliminate the issue that it’s specific to that lemon left aid? If you did switch to a completely new left aid replacement and the issue reoccurred, did you also insist on getting a completely new charger replacement in the case that it’s an issue with the charger?
I know that the Oticon charging instruction tells you to make sure to put the correct aid into the correct slot in the charger (right aid in the slot for the right aid, and left aid in the slot for the left aid), but did you ever try to swap them into the other slot to see what happens?
