Then explain to me why I just paid $175 for a car battery, and after looking around, it looks like I got a deal. (same battery going for over 200)

Yea, AA batteries have definitely not gotten cheaper
AA is a form-factor, not a chemical technology. You can get lithium AA batteries. You probably mean alkaline cells have not gotten cheaper.
I will second the notion that indeed AA batteries, whether Alkaline, Lithium, or Zinc Carbon, for purchase by consumer at a super-market checkout, have not gone cheaper recently.
I will even venture that consumer lithium-ion batteries, such as for camera or laptop replacements, do not appear to have gone cheaper over last, say, decade. I can only assume healthy profit margin by brands (Nikon/Sony/Canon/etc, Lenovo/Sony/Dell/etc). Third party cheaper batteries are available, of dubious quality, so I suppose that may be a sign of cheaper manufacturing...

If musk is to believed, (and I think he's on point with this), $50/kWh will likely come within the next 5 years. So next 9 years? My expectation is beyond Tesla, the rest of the industry will have hit on that sub $50/kwh price point. That is going to make a lot of things really interesting. $2000 for a 30kWh home battery backup? Who wouldn't get one? To further this, with climate change leading to more and more extre…
> $2000 for a 30kWh home battery backup? Who wouldn't get one? Very few of the people that would currently benefit from a domestic backup battery could afford $2k, and most of the people who do have $2k to spare don’t live in places with unreliable electricity. The overlap isn’t zero, but… for example, I visited Kenya with an ex of mine, we met a local friend of hers, that friend would’ve benefited from a more reliab…

There are plenty of places in US where electricity is not entirely reliable, and that includes some fairly wealthy suburbs. FWIW I'd get such a thing for myself even though we see outages maybe once a year - it's less hassle than a generator to keep the fridge running.

And when the natural gas runs out you use what?
It doesn’t go out where I live, but you could instead get a diesel generator and not have to worry about utilities
You can actually get a tri-fuel generator that can run off gasoline, propane, or NG (with some minor fiddling required to convert between the three).
However, it's still a lot more hassle to set this up compared to a battery pack that "just works".

you're paying for the brand, shelf position and other advertising cheap and reputable supermarket brand ones last just long
>cheap and reputable supermarket brand ones last just long Absolutely not. There are plenty of Youtubers testing this theory. Here is a pretty credible reviewer https://www.youtube.com/watch?v=V7-ghrTqA44 I personally have had nightmarish results with Amazon Basics Alkaline. In my experience these batteries have a greater tendency than other brands to leak over time and have destroyed multiple electronic equipment th…

I did say reputable!

#107I just bought a 12v 200ah battery for $2300 AUD. It could be done for less, but this was a premium model. Hopefully when I purchase a second one in a year or two, it will be a bit cheaper.
I just picked up 4 40AH for $70US each so wow.
Mine are like, scooter batteries, LiFePO4. Do yours have like internet connectivity to monitor the charge? Or is it a factor of battery fees in AUS?
Or just 200AH in a single pack? I'm wiring mine in parallel in order to increase AH at 12v. I imagine you're also doing some type of off-grid power via solar/wind?
Re: The price of lithium-ion batteries has declined by 97% in the last three decades
#108That's not the price of batteries in general, that's the price of Li-Ion batteries. Were Li-Ion batteries mass produced in 1991?

#109This is really cool, but could anyone familiar with the domain estimate how far we are along the S-curve? I.e. it took a long time for things to ramp up, then they accelerate really quickly and then they slow down again. Think Moore's Law, which is dead now. What would be the price estimate for 2030, for example. I think we're now around $100 per kwh (or something like that), what should we expect for 2030? $60? $20?

Because it would be a lot more than $2k to get put it in your home. If you do the math on a Tesla powerwall, the raw cost of the battery should be right around $2k too. But it actually costs more like $8k per powerwall.

#110Yes, but their energy density has hardly changed and every gasoline tank beats your average LiIon battery by a factor of 10:
