Rechargeable vs non rechargeable hearing aids

Apologies for my confusion Jim …… It comes easy to me!

Yeah @freezerman404, the vast majority of my power tools are battery powered,(Mostly 18v Dewalt) on count-back, I have 14 batteries, all are between 4AH and 6AH, 2 x were 54 Flexi Volt, but one these no longer works, along with another also original 4AH, they will not take a charge, very unusual for original Li-on Dewalt batteries, but they do become faulty! And like you, I actively seek out rechargeable power tools, but the fundamental difference with hearing aids is, I am restricted to the internal battery, I can swap out my rechargeable power tool batteries whenever necessary. Also worthy of note, rechargeable aids have a BMS (Battery Management System) they will cut out in sub-zero temperature’s, and will not reboot until placed in the charger, this happened to me twice, out in the sticks, in challenging circumstances …. But as always, YMMV. Cheers Kev

Li-ion batteries for power tools are just like those for hearing aids and smartphones and EVs. They do best if kept in a 20% to 80% SOC range. I usually have several for each tool and as I use them, I check the number of LEDs lit and swap them out to stay within a desirable state of charge.

My EGO power tools have quite large batteries that are equipped with vents and the charger has a fan built in so as I charge the batteries, they are air-cooled (also while in use on the tool, too). My DJI drone, which really maxes out battery drainage and battery heating while in use, instructs me to wait 30 minutes after use to allow a battery to cool before recharging! The DJI batteries have no vents and they get pretty warm while in use.

I imagine HA batteries are so small that the surface-to-volume ratio is so great that any worries about overheating the batteries during charging or use at normal room temperature are virtually nil as compared to the larger batteries used in power tools and drones. But it would be great to see the sort of smarts that are available in iOS and Android apps to tell you about the state of health of your battery come to HA’s to give you more info on how your rechargeable HA batteries are holding up. iOS has the “Battery Health” indicator, which at least helps inform you as you’re going along ~how much usable lifetime you have left. Most of my other Li-ion battery powered devices, including my HA’s, offer no info on how the battery is holding up and the user has to guess by how fast the battery drains.

Where I live South East Louisiana subzero is not an issue.
If I wake up to subzero temperatures one day my hearing aids would be the least of my problems.
Now power outages yes.
I usually charge the charger in car if I have to.
Bought a solar charger.
Haven’t tried it yet.

Not familiar with the term. Is that what we call a nip? ~1.5oz?

@WhiteHat: Nope, 10oz. is the smallest worth bothering with. A Mickey Finn.

When I think of a mickey finn, I think of a drugged drink that takes you to next week. But one of my boys is known for having lots of nips. An open liquor bottle in a vehicle can get you in trouble. But a still sealed one isn’t bad as long as you aren’t over the limit. This has lead to a huge trash problem in my region where these things line the streets – empty, of course, and picking them up along with the caps is a PITA.

Saw this looking it up: Mickey Finn (Wikipedia)2

I’ll remember this thread the next time Spud complains of posters not sticking to topics related to hearing aids…

that said, I like a little diversion too. have at it!

@jeffrey: I rarely do what you’re accusing me of unless the deviation is for abusive purposes (as yours often are, BTW).

I think rechargeable vs nonrechargeable is a Chevy vs Ford type augment.
Both sides have their reasons for which one they prefer.
No one is really wrong

Actually, I think it is a bit more complicated than that. I believe that a person s positions on this issue probably suggest their position on many other unrelated issues. Change can be difficult.

Generally I think you are correct.
Change can be hard.
But as Spud pointed out, there are legitimate reasons to prefer one over the other.
Kev pointed out a good reason. I’m sure they are many others.
I just wonder if, going forward how long the hearing aid companies plan on giving people a choice.

I’m not accusing you of anything! I was mildly kidding you, as I thought I made clear by the full, short post. As I already wrote, I like yours and other folks rambling off topic a bit. No harm!

I don’t think having a different opinion from another person is the same thing as being abusive. As now! is my stating my mind…being abusive? No.

No, it’s not … it’s just that sometimes -it appears from where I’m standing - that you’re stalking me and sniping. I don’t like that, and I react badly when I perceive it to be happening.

I honestly didn’t pick up on the jocular intent of your previous post. Today is another day, and we’re all good.
