That's not the price of batteries in general, that's the price of Li-Ion batteries. Were Li-Ion batteries mass produced in 1991?
There's a graph there on market size, which shows the market size has grown 50,000x since 91.
I don't think this applies to Duracell or Energizer alkaline batteries unfortunately :( Of course reading the article they are talking about Lithium Ion batteries.
I checked Radio-Shack's 1981 US catalogue. $2.79 for a 4 pk of store-brand AA alkaline cells. That's $8.20 or so today. You can today, apparently get an 8 pk of Duracell from Wal-Mart at $7.50. Or an 8 pk of store brand alkaline AA cells from Wal-Mart for $3.20.

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…
My expectation is that with climate change, unreliable electricity is going to affect a lot more places. The polar vortex that knocked out the Texas grid is likely to be a more frequent and more extreme event. ACs running more frequently will likely lead to more brown outs.
Assuming our grids don't get major updates (I'm pretty pessimistic about this), we are looking at more and more outages in the future. It's certainly possible that smart grids could significantly reduce outages, but that will take too many actors working together to ever really fly.
For example, if the grid could coordinate with your heating and cooling, you could distribute AC usage to avoid tripping the grid.
Barring such a grid, homes having batteries would allow owners to skate through brown outs. Further couple that with solar and they could survive even major outages (hours or even days).
> 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 reliable electricity bill, but her monthly rent and utility bills combined was equivalent to about $85 and she couldn’t afford to move.
A 1kwh battery would probably be a pretty positive impact. Add on a 300W solar panel and you'd have something that would extend the amount of electricity the have. That'd come in at ~$400 (assuming $50/kwh). Not enough to run an AC, but enough to keep the lights on and maybe run a fridge.
Otherwise... yeah... not much good news for places that can't afford such batteries.

The other commenter says that they were first introduced as a commercial product in 1991. According to Wikipedia, they were preceded by two years by the first commercially-available nickel-metal hydride cells in 1989, so that would be an interesting point of comparison. Also nickel-cadmium and lead-acid have been around for a very long time. https://en.wikipedia.org/wiki/Nickel%E2%80%93metal_hydride_b...

I would rather spend a few thousand more for a natural gas generator, it will run indefinitely as long as you have natural gas.
If the whole grid goes down, your gas likely won't be there.
If you add solar, then you could indefinitely run in most circumstances.

you're paying for the brand, shelf position and other advertising 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

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 that I have owned. It was a big mistake on my part because I bought a large package of them, installed them and then didn't realize that many of them leaked until it was too late and they have eaten away many terminals in the different devices I put them in.
