Before the current epidemic of disposable vape pens, Poundland used to sell these disposable phone chargers which had a 650mAh #lithiumPolymer battery connected to a DC-DC boost converter. There was no straightforward way for owners to recharge them.
I've been distracted by e-cig battery harvesting, but finally got around to adding a TC4056A module with over-discharge protection to the few I bought back then
They are now just like USB #rechargeable powerbanks

No, #SmokeDetectors, I really didn’t have #spoons for you today. But despite being #hardwired, chirp you certainly did begin! Sadly those spare #batteries we had were too old. So rather than listen to you all night, with your every minute chirps, off to the store I went. And after sone ladder fumbling and swearing you are silent again for a while more.
I’m still not sure why a hardwired device isn’t a good situation for a #rechargeable battery… if it’s good enough for my OG #Nest…

whoa, this is so cool. wonder how long it holds a charge

A team of #researchers at the #IstitutoItalianoDiTecnologia ( #IIT - #Italian Institute of #Technology ) has #created a totally #edible & #rechargeable #battery - starting from materials that are normally consumed as part of our daily diet. The #ProofOfConcept #BatteryCell has been described in a paper, recently published in the #AdvancedMaterials journal. The possible applications are in #health diagnostics, #FoodQuality #monitoring & edible soft #robotics .

I wish it were mandatory that all common consumer devices that are #rechargeable had easily replaceable #batteries. Countless phones and other devices are constantly being trashed when they could be useful for many more years.

I am so angry right now. A storm blew through and I had a really nice chance to get some recordings, but all of my batteries are dead. Either the self-discharge on these NiMH cells is *way* worse than it's supposed to be or my charger is fucked or my recorder is fucked. >:[
I'm not sure which possibility I like least.

Does anyone have any practical experience with rechargeable CR2032 coin-cell batteries?

So, #Battery question:
I am buying my mom some LED candles for #Christmas.
And I want to buy rechargeable batteries for them. I already have this recharger: https://www.amazon.com/Panasonic-K-KJ17MCA4BA-Individual-eneloop-Rechargeable/dp/B00JHKSMJU/ref=sr_1_2_sspa?crid=1AR2N1828AMSX&keywords=eneloop+charger&qid=1670078508&sprefix=endloop+recarger%2Caps%2C63&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzRjVRRDBIWDE3MjhEJmVuY3J5cHRlZElkPUEwOTI2ODAzMU5VNEhHWURLWlZQMCZlbmNyeXB0ZWRBZElkPUEwNzU3ODc4M0JFMFpMRTZCS0FZOSZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=
Should I buy more Endloop batteries? Or will cheaper ones not explode in this?
Any advice?

Did you know that alkaline #batteries are actually #rechargeable? Just discovered the project #regenbox that lets you order a #DIY kit. https://en.regenbox.org/
