Are there "better" batteries than the #Fairphone4 stock battery?
Or should I just buy from #Fairphone official website even though it might be 3 year old tech (at least it's from certified resources)
Recommend me things to buy / read into

Another abandoned #vape on my walk this morning, although this one is both #refillable and #rechargable.
Another free #lithium #cell for my collection ๐
Latest #reuse #recycle project is replacing the #rechargable battery in my #Panasonic hair trimmer. More than 5 years old and it recently went from fully charged to flat almost before finishing a haircut.
Anyway it's NUTS how a standard gadget has been designed to get thrown away rather than replacing the battery.
* 12 screws
* 2 press on covers to risk breaking
* Unique battery design with no product number
Ordered a replacement for ยฃ7 + postage. It'll *probably* work!

Short follow-up: one or two days ago, the battery seems to have been drained enough to stop it from working. It's voltage measured about 2.3V, so still high enough to not damage the battery. I think 5 months for one charge is a very good time.

Canโt remember the last time l had rechargeable batteries and a charger since the 80โs lol ๐ #batteries #rechargable
After someone kindly donated a load of used #disposable #vape devices, I now have quite a stash of salvaged #rechargable #lithium #batteries.

Going to have to think of a project to use themโฆ ๐ค
And another one todayโฆ ๐๐คทโโ๏ธ

Another disposable vape device found on the street.
These contain rechargeable lithium cells so I collect and dismantle them for reuse.
These things should be banned as theyโre a criminal waste of resources but theyโre an excellent source of batteries for projects ๐๐

Weather Station Dumps CR2032 Cells, Gains 18650
Despite the fact that we're rapidly approaching the year 2022, there are still an incredible number of gadgets out there that you're expected to power with disposable batteries. Sure you can buy rechargeable stand-ins that come in the various shapes and sizes of the traditional alkaline cells, but that's a stopgap at best. For some, if a new gadget doesn't feature an internal Li-ion battery and standardized USB charging, it's a non-starter.
[Danilo Larizza] is one of those people. Bothered by the fact that his Oregon Scientific weather station required a pair of CR2032 coin cells, he set out to replace them with an integrated rechargeable solution. The conversion ending up being easier to implement than he initially expected, and by his calculations, his solution should keep the unit up and running for nearly 40 days before needing to be topped off with a standard USB charger.
The first step was determining how much power it actually took to run the weather station. Although the two CR2032 cells were wired in series, and therefore providing a nominal 6 V, he determined through experimentation with a bench power supply that it would run on as little as 3.2 volts. This coincides nicely with the voltage range for a single 18650 cell, and meant he didn't need to add a boost converter into the mix. He notes the weather station does flash a "Low Battery" warning most of the time now, but that seems a fair price to pay.
Confident in the knowledge that the weather station could happily run with an 18650 cell connected in place of the original CR2032s, all [Danilo] needed to do was figure out a way to charge the battery up from time to time. To that end, he reached for a common TP4056 module. This handy little board is a great match for 18650 cells, and is so cheap that there's really no excuse not to have a few of them kicking around your parts bin. You never know when you might need to teach an old gadget new tricks.
