Ban of non-rechargeable batteries

look at powerex and tenergy for rechargable D cells (better then those ridiculous adapters). With LSD technology it makes sense to use larger NiMH cells for D and C applications. Those adapters are a serious stopgap measure and for emergencies. I hate how its wasted space.

The way to find if a D or C cell is good : look at capacity 4000+ for a C and 8000 for D (less then a primary C or D). The rechargable cell is like a Zinc Carbon without the leaking problems. A bit better I think.

The tradeoff with NiMH is that if you put low self discharge technology in it, it lowers the capacity at the benefit of extending life.. most battery manufacturers sell 2 types because it makes sense to (a battery hungry super flashlight thats actually used and not an emergency light will benefit from high capacity higher self discharge batteries)..

But IMO, you either go with Alkaline or with NiMH LSD, in most cases, the high self discharge batteries are too frustrating to use IMO. Its like stuff for businesses where you can put a flashlight on a work truck that gets used alot and will also be recharged as a result of employee training), or for calculated use (i.e. keep a set handy for putting into a data logger or such that you know will be used for sure within some time frame). Using batteries right requires planning. Those high self discharge batteries IMO are too situational, when you need them even for a known duration event they will likely be uncharged and it will delay you to use them, so alkaline is great. I am not willing to go into that level of management. They do however serve a purpose...

Also for some operations if you consider TIME and MONEY, it makes sense to just throw the things out instead of bothering with recharging them, since its faster and you get more throughput.

Many ideas have been discussed over the years, many projects have been drafted (e.g.: AA cells with Micro-USB charging feature), yet still every remote of the planet keeps eating standard AA/AAA cells.

In your opinion, why is this obsolete piece of technology so difficult to eradicate? Is the problem on the technical side or more on the political side?

Thank you in advance for all your thoughts.

Just because a product or technology has been around for a long time doesn’t make it obsolete. Wire is an old technology, but it’s hardly obsolete. Jars are ancient technology, and still absolutely relevant today.

The fact is, with lithium ion batteries being such cheap, good performers, I’d hazard that most applications where rechargeable makes sense already ship that way.

Infrared remote controls probably make up the vast majority of standard-cell powered devices in my home. Everything with even slightly higher power consumption is already inherently rechargeable, from phones to speakers to flashlights. (The only device I can think of that really uses rechargeable AAs is my old Apple trackpad. I use it with NiMH. But the newer version of that device, the one sold for many years now, uses lithium ion.)

having to recharge stuff in a pinch sucks and it sucks even more for businesses. They will LAUGH at the cost of batteries for the stuff they do. Its debilitating to maintain space and procedures for charging.

Basically you are getting into 'fleet ownership' when you go into rechargeable batteries. Disposable keeps things running so long the stores are open. The last thing some office needs is some battery nazi telling people to recharge stuff all the time.

So I can come home and I want to cook meat then some batteries need to be charged for a thermometer because I was busy with things and I got to find a charger and plug stuff in and give me a fucking break just put some god damn AA's in the fucking thing and GET ON WITH LIFE.

Yep. And they’re so cheap that for critical applications, they’ll replace them preventatively, dead or not. For example medical devices. But also things like wireless microphones for concerts. Spending $20 for all new batteries is peanuts compared to the cost of having a $200,000 event not go smoothly.

I think your numbers are too high. Delays piss off people in events very quickly. I would do it for a 500$ profit show at a bar. Cost of doing business. Like you want to delay drunk people for 30 seconds so you can put money in your pocket at the end of the night. Think of business like that scene in the movie 'oceans 11'.

I think that some people in this thread would pull out a fucking dynamo and spend 30 minutes cranking the thing to fix the detonator for a bank robbery.
