Decided to give my old 2015 mbp a past lease on life with a new battery. The ALU body had actually started to deform from the swell of the battery.
Sometimes couldn't even click the trackpad properly anymore.
Closing the lid was impossible, it just stood there with a 3 cm gap.
The amount of energy needed to warp an ALU body like that... Scary stuff.
For the amount of money this cost, it ought to reach 10 years of usage tho. So I opened her up and holy moly.
We show 5% degradation on our 5-year-old #Tesla Model 3 125k kilometres/78k miles. We rarely charge to 100% and mostly charge at home, which seems to help the situation.

Historical use from May to Aug
We imported 405kwh at a cost of £65 (not inc standing charges or VAT) which would then bring the total to about £96
Let's work that out if we didn't have solar & battery system.
Total energy use 1918kwh + 4 months standing charges, + 5% VAT = £351
That's a saving of £255
Not bad for 4 months.

Blimey. My Apple Watch just hit 10% battery after only 9 hours of wearing it today…
Normally it’d end the day (another 7 hours from now) with 35-40% remaining! And I’ve been using it *less* than usual today. I haven’t even done my usual ~1 hour outdoor workout yet 😳
Hopefully this is just a "day after update" thing and it’ll improve over the next few days, or something is seriously wrong.
24) Further to my last post, I remarked to my wife that had our car been electric, we wouldn’t have had a catalytic converter to steal 😜
Truthfully, In a dense city like #NYC with a plenitude of transport alternatives, #CarFree makes sense. A private car only makes sense if you leave the city frequently.
That said, I wonder how quickly #Toyota are going to bring this new tech to the market. Could be a game changer 👇

"The NTU approach entails submerging expired solar cells in hot, diluted phosphoric acid for half an hour to remove surface metals. This procedure is then duplicated with fresh phosphoric acid to ensure comprehensive metal extraction, ultimately yielding a pristine silicon wafer within an additional half-hour.
The team also claimed that advanced spectroscopic analyses confirmed that their sample achieved a recovery rate of 98.9 percent with a purity of 99.2 percent.
Dr. Sim Ying, the lead author, claimed that the similar performance levels exhibited by their upcycled silicon-based lithium-ion battery and freshly procured ones provide evidence for the viability of the NTU approach.
They anticipate that their silicon recovery technique will significantly propel the advancement of EV battery technology.

I have a 2017 #iPhone SE that I have always really liked and still use from time to time when I just want to carry a compact phone around. But the #battery #charge level readout started acting weird. When I unplug it from the charger it will seem to discharge very quickly, then randomly, and then it will continue to hum along at 1% charge for hours. I have no reason to assume that the battery itself is in bad health (Battery Health says it's fine) so what's going on / what can I do about it?
In a US first, new EV battery cells are going to be made with recycled metals, which could lead to a 25% drop in CO2 emissions in the production process.
Four companies will be working together to create the new batteries, including a Canadian company. Commercial production of the batteries is set to begin in 2024.
Yes! Sounds like a good start but we need more reclaiming and recycling of battery materials, please. 🙏

A friend asks me if he could supply a 52V / 1000w motor for about 20 minutes with home made #battery (stack of 18650 modules). The goal is also to have a not too heavy pack.
If you had to build a such battery, which configuration would you mount ?
Thanks for your help
And just in case someone is eventually going to trot out the ridiculous "for reliability/people can't change batteries" drivel: when Kidde's "Never Replace Battery-Lasts Ten Years," "Eliminates Late Night Low Battery Chirps" failed after 3 years, I was unable to stop the alarm from ringing at 4 AM without destroying it. Broken by design. #SmokeDetector #Battery #Safety
Car battery died (could not hold voltage). I replaced the it with a new one in the car.
I thought I could use it at least to power my speaker. Nope, charges "to full" in like a minute, and then (sipping a few watts) goes from 12V to below 9V in a couple minutes, I can watch the voltage drop live.
Any tips on whether I could revive a dead "no maintenance" battery? Or is just "dispose of appropriately"?

#Battery technology doesn’t seem to have evolved much in the last decade, at least at the consumer level. I was hoping that by now, phones that last several days on a single charge would be ubiquitous.
Nuclear power is a distraction. The cost is silly and times sales too long.
You can get #solar #wind #battery systems up and running quicker and there is no lack of investment. Governments are actively obstructing #renewables while they can't get #nuclear projects going because no one wants to invest and the logistics are a nightmare.

Have the benefit of seeing lots of models of #ebikes in the bike rack on the #Baylander. They are all beasts! My class 1 #ebike weighs 36lbs with the battery and the #battery only holds 7AH. The motor is small at 250w but that is totally sufficient.
NASA has developed a breakthrough solid-state battery that uses sulfur and selenium as the cathode material. The battery has a record-breaking energy density of 500 Wh/kg, twice as high as conventional lithium-ion batteries. The battery could enable electric aviation and other applications that require safe, powerful, and lightweight energy storage. #battery #NASA #sulfur

We recently upgraded our home solar storage to 4.8kWh. The battery has sensors to detect how much solar power we're generating, and how much electricity we're buying from (or selling to) the grid.

Nothing has damaged #Detroit and #Michigan more than the #automotive industry - from multiple fronts and multiple perspectives.

The amount of state incentives that have currently been spent on #BEV #battery facilities is too much at this point.

The University of Texas at Austin says that John Goodenough has died. He did research critical to the development of the lithium-ion battery, which has transformed our daily use of portable devices. When he won the Nobel Prize, at age 97, I asked him if he remembered the first time he ever owned a cellphone or some other device with a lithium-ion battery. He said, "No, I don't remember when because I've never carried one of those things in my pockets," and then he laughed. #battery
