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.
A brief overview of #Battery Technologies and Types of Batteries. Also some recent advances in Battery Technology.
Listening to ''material world' by Ed Conway on BBC sounds, and it has blown my mind that #lithium originated in the #bigbang and was stored for millions of years in #brine under the #Atacama desert, and now ended up someone's phone #battery and in my #brain. I take it every day as I am #bipolar. The book addresses the environmental and human costs that lithium extraction has. We need to transition to a green economy but doing this ethically is not simple!
“Lemmo One is both an electric #bike and a conventional mechanical #bike, with the conversion achieved via a removable #battery pack that attaches to the frame and a hub motor on the back wheel that can be disengaged … slide the battery pack into its slot under the top bar of the frame to activate #ebike mode”
"the pack can be easily sent away for repairs and even be upgraded every few years, extending the vehicle's lifespan” https://www.dezeen.com/2023/09/22/lemmo-one-springtime-design-bikes/ #bicycle #cycling #design
Here's a guide to compare inexpensive (under 20 $) #Zigbee temperature and humidity sensors.
They are classified according to: Temperature accuracy, #Humidity accuracy, #Battery life, #Zigbee2MQTT Clusters
#iPhone 15 provides more details on #battery health and lets users limit charge to 80% — I hope this feature will be available to previous models, so I don’t need to rely on smart plugs + shortcuts automations anymore 😅 https://9to5mac.com/2023/09/20/iphone-15-battery-health/
Middle of the night. Something downstairs chirps periodically. Must go track down electronic device that presumably has a low #battery. 😠 🔋 Don't know what else the noise could be.
Also grabbed some tools like a glassfiber scratch pen to help #RGH3 my 360s...
If ever the 'won't somebody think of the children' argument had a place, it's right smack in the middle of this nonsense. This is a simple #ClimateCrisis argument: "Do it for your Kids" and "Do it for your Grandkids"
Sunak U-turn on green policies puts Labour in difficult position | The Guardian https://www.theguardian.com/politics/2023/sep/20/sunak-u-turn-on-green-policies-puts-labour-in-difficult-position
"Lead the Charge, an advocacy network tracking the supply chains of the world’s leading automakers, says many are making progress on their efforts to eliminate #emissions, environmental harms and #HumanRights violations. “But as an industry,” it says, “there is a long way to go.”"
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 😜
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"?

August is meant to be full of gloriously hot days. An endless parade of sunshine and drinks in the park. This year it seemed mostly grey, miserable, and prone to pissing it down at a moment's notice. We all know that solar panels' efficiency wilts in the heat, but do they get a tan work […]
Nissan is reusing the batteries from old Leaf electric vehicles to make portable power sources
#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.
Nuclear power is a waste of time.
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
Can anyone help me decipher the codes on this (rather puffy!) #battery? Trying to replace it in some consumer electronics, but not sure what its voltage is meant to be... advice appreciated! Going with a 3.7V 550mAh replacement as a default in the absence of any better ideas 😅

🆕 blog! “Solar Battery Statistics - Day One”
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. That means... GRAPHS AND STATISTICS! Our battery was commissioned just after midday. This graph shows: 1630 - it was fully charged. 2…
I have said it before, and I will keep saying it...
And although I believe that some public officials here are starting to (finally) recognize that, we must be far more aggressive in shifting away from this industry in Michigan.
🆕 blog! “Review: Moixa 4.8kWh Solar Battery”
I have upgradeitis. If something newer and shinier comes out, my stupid monkey-brain compels me to buy it. Seven years ago, we installed a solar battery. It was part of an experimental project which looked at creating a community power-grid, so it came at a subsidised price. As I explained to BBC Click, the 2k…
Following up on yesterday's story about China's new battery-powered container ship, here's a recent Condé Nast Traveler article claiming that electric ferries are about to take over the world.
As someone who lives in a community accessible only by boat, I would love to see electric ferries and other forms of zero-emission waterborne transportation become more popular!
@pezmico What I do think would be a longterm gamechanger are #Methanol #Fuecell-based #ElectricXars since they basically solve the #battery issues aka. #range and #chargung since said #Methanol can be made fron #renewable electricity and be distributed efficiently like #gasoline, making it a viable option for places where batteries would be considere too unreliable and restricting, like fire trucks, ambulances, emergency power generators.
NASA may have just cracked the code for replacing lithium in batteries: ‘Double or even triple the energy’
They're trying to use solid state batteries.
At what point do home batteries become as ordinary in the US as rooftop solar? Interesting that Tesla is offering $500 rebates on Powerwalls. https://www.cnet.com/home/energy-and-utilities/startups-big-battery-can-electrify-your-home-and-make-the-grid-greener/

I am Jourei, from #Finland, fluent in #finnish #swedish. I almost exclusively post in English. I have no specific topic, I just yell into the void whatever I feel like. I avoid politics and controversy.
...the rapid rise in #battery storage means that the setting of the sun no longer means the power goes away...
In other words, the power of the sun gives us a chance to allow the functions of the world as we know it to continue, and to continue without increasing the temperature of the earth."
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
"#CleanEnergy technologies — including #wind and #solar power, #battery storage and #ElectricVehicles — are now competitive and in many cases cheaper than coal, oil or gas. That progress has been led not only by #Europe, but by #China, #India and other emerging markets such as #Chile, #Morocco and #Vietnam. The world’s cheapest electricity today is generated by the sun in the oil-rich United Arab Emirates."
Fediverse help me
I'm looking for a COTS or MOTS option here. I can do some soldering if need be.
I am looking for a DC input charge control board for some #LiFePO4 batteries. Ideally 12, 24, or 48 volts, and at least 100 Watts. 2 stage constant current/constant voltage, of course.
I have searched high and low and everything available is an AC/DC converter. I specifically want a DC input.
Anyone know if #solar mttp chargers are acceptable to use with DC voltage generators?
Happy summer solstice, northern hemispherians.
