Regular Batteries versus Rechargeable


Wow, we do get off track here, huh? Backpacking in the wilderness, ham radio, blowing up things with one’s chemistry set. Ah, I remember doing all those things in the good old days of adolescence (K3GMT here, although W0AOY for a year in the middle).

But to get back on track a bit, I believe my initial resistance to the idea of rechargeable batteries comes from my experiences in olden times when rechargeable batteries were pretty punk. Some still are, like the ones they gave up on with the wireless mics at church (we’ve “updated” with ones requiring AA batteries).

More recently, I started to remember visiting my nonagenarian mother. The first thing I’d have to do when I’d go visit was to replace the batteries in her HAs so that we could chat. She no longer had the digital dexterity to change them herself. Good son that I am, I’ve inherited my mother’s penchant for arthritis. As a result, I’ve recently noticed that changing those tiny batteries is getting difficult. I still think my next HAs will probably be the replaceable type, but I’m guessing that in another 10 years, I’ll be looking at rechargeable ones myself, if only to save my children from having to change batteries for me, and during times before they visit, not being able to communicate with my spouse.



Glad to see another battery nerd on here Jim! And I mean that as a compliment. Battery University is great for a battery primer, but definitely not cutting edge or always up to date. There are lots of new lithium based battery types out there now and polymer has been really popular for custom applications. We’re about to try out some Lithium Iron Phosphate, (LiFePO4) which are pretty promising.

I’m sure the manufacturers are getting better and better at the number of charge cycles which is great. My concern still with these hearing aid batteries is that they are likely to run pretty full charge cycles each day of use and there is limited ability to top them off during the day due to inconvenience unlike a phone where you can handle having it plugged in or resting on a charge pad. Like TraderGary said, I’ll probably be on new tech in 2 years anyway, so it’d probably be fine.

The HAM radio stuff has been really interesting for me. I just got my license a few years ago, but it was for the sole purpose of communications during off road riding/racing. It’s cool hearing about guys bouncing signals off the ionosphere, but I’m not even playing in that realm. The real HAMs can be really hard core about that stuff! Maybe someday.



For Chromebooks if one wants a battery test, enter CROSH (like C prompt in Windows) by hitting CTRL/ALT/T and typing battery_test



Sorry, @jim_lewis, if my comment came off as critical. It was not meant to be. I was trying for a touch of lightness, I think. I actually love getting to know people better and getting to know their backgrounds and proclivities. I rather enjoyed reading your flagged “off-topic” post. Such things bring back memories, and I certainly knew people who became chemists in later life who did some weird stuff with their chemistry sets back in the day (some even with MIT associations). I tried, but never managed more than some brilliant flairs and stinks. I think it also helps to know from where one might be coming when they opine about hearing aids, batteries, audiologists, and the like. So throwing in the bit of the personal helps with the filtering process.



That’s hilarious! I wouldn’t be surprised if the forum platform auto-flagged it with the technology these days. I did a lot of dumb and dangerous things learning things the hard way, but I’m to prideful to share :slight_smile:
