Hi I was wondering if there any people on here who use the oticon cros with battery who know how long the batteries last before you have to change them? I currently have the phonak cros ii with nathos auto m and haven’t used them for two day due to my ears being sore so took the battery out of them and left them come back this morning and put the batteries in and they immediately died I’m getting sick of this as it’s not the first time this has happened so was considering asking about the oticon cros again but first wanted to know if anyone has an idea of the battery life. Currently on my phonaks I get 4 days out of the nathos auto m since they changed it and between 1 and 2 days from the cros ii

Any hearing aid does this. It’s how hearing aid batteries work. They continuously drain. Oticon won’t be any different.

All depends on hearing loss and a lot of other things. No two people will be the same.

@Zebras thanks for that do you think I should ask them to change the cros ii as well? because i get a lot better battery life from the nathos auto m now than the cros ii but don’t know if is to be expected for one side to drain faster than the other. Still would also be nice to know kind of what the average battery life on the oticon cros is like

CROS will always die quicker due to it being a CROS.

@zebras thanks for this it just i use to get about 7 days worth of usage out of both the cros ii and nathos auto m before having to change the battery. I now get 4 days from the nathos auto m and 1-2 days out of the cros which is such a difference to what i use to get. I feel like I’m nearly always just about out of batteries by the time i have an appointment where as when i first got them i hardly needed to get more batteries at every appointment now i have to get them at every single occasion i go there.

@LRav

Has your hearing loss changed in the time you used to get 7 days?

That does seem quite excessive for the CROS. Most people get around 2 to 4 days depending on a lot of things.

Wouldn’t hurt to get the CROS changed tho.

@Zebras my hearing hasn’t changed for quite awhile it has been stable since i stopped getting so many infections. I was originally told that with my cros aids i could expect up to ten days of battery life so i was very pleased to get that up until this last year. Will ask about the cros being changed but at my last appointment the person didn’t seem to think that the cros would need changing as well.

10 days is really not going to happen on a CROS. Maybe your hearing aid side but definitely not a CROS.

Altho 10 days on your HA side is still excessive as my 675 batteries last 10 days.

I think you’re wanting something that isn’t going to happen. Even your HA side has to continuously receive the signal from the CROS which will affect battery.

@zebras sorry i mean’t to say that i think what the person mean’t was a combined battery life between both hearing aids of up to 10 days i never expected that long as back when i use to wear just one hearing aid i always got at least seven days battery life so was happy to get that at first with the cros aids that i got that long but these days the cros ii always seems to run out well before the nathos auto m and is very unpredictable.

Very normal as it’s a CROS and continuously sending signals to the Aid side.
