Should I be skeptical about rechargeable hearing aid?

Hearing Aids
#371

I honestly never think about my batteries running out - I get a tone about an hour before they are going to die (usually I find I have more like 2-3 hours) and either I change them or ignore it if I’m not doing anything that needs uninterrupted hearing. But I’ve had pretty severe and profound hearing loss my whole life so I’ve been managing and passing for a long time. With or without my HAs I need captioning to consistently understand others in a meeting or presentation so if my HAs die I always have the captioning in place anyway. Prior to live captioning becoming readily available in the last few years and reasonably accurate everything was a lot more challenging and I really relied on my HAs always being on.

I also have no qualms changing my HA batteries in public if I really need to though usually I step away if possible - I’m always surprised at how little other people notice.

I accepted that common knowledge until I started paying attention to the battery gauge in my Real 1 312 aids. There is information to be gleaned from the numbers it shows. Two posts of mine earlier in this thread:

An unloaded voltage reading, perhaps, which is useless. The app-reported (or MFi-reported) charge level, while admittedly not linear, is based on voltage under actual load.

Guys, if my Signia Pure 7 IX doesnt lie, then after 7H of non-stop streaming i still have 90% of battery

I appreciate @x475aws, you might pay closer attention to a 312 battery, as opposed to a 675, the runtime is vastly different… I just wouldn’t use a battery gauge, even if it where highly accurate, it wouldn’t float my boat, but each to their own… Zinc Air, just works, and it works well… I am highly interested in LiFePO4 Lithium Batteries though, I have literally thousands of pounds worth, and because they are extremely expensive, replacing them is cost prohibitive, so I like to take care of them, I have approximately 21kw of of LiFePO4 rechargeable battery bank, with 4kw of solar on my house roof, on top of that, all my Dewalt tools run on either 18 volt, or 54 volt rechargeable batteries, I have at least 6 chargers, and about 20 batteries, between 4ah & 6ah, you could say, I am am a lover of all things rechargeable, with one extreme omission, I do not (as yet) rate Lithium batteries worthy of my hearing care needs, but I am certain at some point in the future, they will make an “Ultra Power Hearing Aid”, with an excellent runtime, (Perhaps 2 to 5 days) with easy access to replace a Lithium rechargeable battery, so we can hot swap out, with a replacement recharged battery… When that day shines, I will be first in the cue, Cheers Kev :grin:

100% my experience as well. I have zero issue with changing my disposables.

Guys your all kidding yourselves, let’s get real, with this new technology I’m all in for the rechargeables, how about “never” needs charging and could potentially last 50 years!

That’s what today’s rechargeables will need to do to get me to accept them: make them last 50 years between charges. At 44, I have probably 25-30 years left on this earth, statistically speaking. I am not sacrificing my hearing for the hours it takes to recharge.

They might be fine for retirees who don’t have a career anymore and don’t care about that aspect. But they are not for me until they can guarantee no downtime with my hearing.

Heather_R I think you have said you have been wearing HAs for a long time. If so, have all of your HAs given you this much notice before the batteries die? I only had 1 pair of disposable battery HAs and I only got about 15min warning so I figured this was normal so I’m curious to know if this is not normal / standard.

My Phonak Naida B UP + CROS Unit (before they pissed me off and don’t provide support for my hearing loss anymore with a Naida UP CROS Unit) gave me around 2 hours of warnings before they died.

I believe I’ve been getting warnings since my first Phonaks when I was a teenager about 30 years ago. Always 1-2 hours of warning with a beep every 30 minutes. I think they may get less accurate with time - my last HAs which were almost 10 years old by the time I replaced them were giving me warnings 1-2 days before actually dying at the end :smile:

Edit: I’ve been wearing BTE UPs my whole life and I wonder if that might be a factor in how the warnings work.

#384

I would say it’s about an hour @Heather_R , but it’s probably longer? I haven’t timed it though, much might depend on the battery size? 675 batteries being bigger, perhaps you an earlier warning beep? Cheers Kev :grin:

Thanks, thats interesting! I wonder if as @kevels55 says below it has to do with battery size? Mine were CICs with size 10 batteries, so pretty small batteries. I had them for ~6 years and don’t ever remember getting more than about 15 min warning. Although I did discover that if I took them out and opened and closed the battery doors I got a few extra minutes.

I’ve had 13’s since my teens I believe. The 675’s are new to me. Only 15 minutes warning is pretty limited, I would find that annoying too. With an hour or so warning and multiple beeps before it actually dies any time I’ve had my hearing aids die in the middle of a conversation during my adult life has been entirely my fault :smile:

I’m with you. I was a little concerned when I transitioned to rechargeables, but now I would really be disappointed if I had to go back to those darn batteries. It’s so much more convenient for me to just pop my HAs in the charger when I go to bed and pop them back in when I get up in the morning, and not have to remember to take batteries with me whenever I go out. Other advantages to rechargeables include: easier for those who may have dexterity issues, they are more moisture resistant, and you don’t have the risk of breaking a battery drawer hinge (which I have done before). Having said that, to answer the OP, I don’t think there is any reason to be “skeptical”, but I do think that your lifestyle should be a factor in your decision. For example, if you work in a job with long shifts, rechargeables may not be for you unless you can afford a backup pair. And just a reminder to those who haven’t yet transitioned to rechargeables, if your HA battery charge is getting low, you don’t have to charge them to 100% before wearing them again (sort of like a smartphone). And full disclosure here – I do have a backup pair, and they are also rechargeables. While they were still under warranty I had the batteries replaced, even though the batteries were still good. I upgraded from Phonak Paradise to Lumity because the former just were not working well for me, and the Lumities are a huge improvement. There are obviously those who embrace new technologies and those who will fight it tooth and nail, but like you, I think the handwriting is on the wall for replaceable batteries, but I’m not necessarily sure that’s a good thing because it’s good to have choices. And to the OP I would suggest trialing rechargeables and see for yourself whether they are right for you

@Liviu do you have the Signia Pure 7 IX T version or the regular (non T) version?

#389

I trust you’ll perform the recommended battery maintenance on the backup pair every 6 months or so.

I’m not sure what that is, so I probably won’t do it. :stuck_out_tongue_closed_eyes:
