@Ollital gilt das für alle oder nur solche die -Ionen / & / - Akkus haben?

Gilt wie bei & das 100Wh - Limit oder ein Gewichtslimit??

Sind eigensichere und nicht-brennbare Akkus wie ausgenommen?

Before the current epidemic of disposable vape pens, Poundland used to sell these disposable phone chargers which had a 650mAh 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 powerbanks

Haven't seen a single-use device in this form factor before. Found discarded in the grass along the side of a public footpath

Internal battery is rechargeable via USB-C but the tank is not refillable. It has a voltage of 3.7V

Whether or not these disposable devices get banned, the astonishing level of that is bordering on scam territory, should be sufficient reason to stop buying these single-use

The 550mAh (date code 221101) was found in a discarded Elfbar 600 from earlier this year.

The 360mAh battery (date code 230417) from an Elfbar 600 I picked up from the side of a road today

Found all these disposable devices by just walking into town and back today. Passed by a few that were little more than shattered remains in the road. Even the run overs might still have salvageable electronics -- the pressure sensor can be repurposed as a capacitive touch switch

At this rate I'll easily exceed the number I found last year.

And now Becky Stern has joined the disposable salvaging club

Although she hasn't yet suggested anything about what to do with the pressure sensing (aka capacitive touch) switches.

That pressure sensing capsule found in most disposable pens can very easily be turned into a switch that is capable of switching currents high enough to activate small relays and solenoids

Simply slice the top off, exposing the the edges of the inner and outer conductive cylindrical walls. Bridging the two walls with something no more conductive than human skin is sufficient to trigger it

This is the most deformed lithium polymer battery I've found on the street that still had a significant charge (3.5V)

It used to be cylindrical but now has a 11mm x 14mm cross section

I won't bother discharging the the damaged one also found on the street today. I intend to dump both in the battery recycling bins at Asda tomorrow.

Look at how small the battery is in relation to the size of the disposable
1.48Wh (400mAh 3.7V)

Might be useful should I need to replace another battery in some wireless device, assuming I can recharge it - voltage is reading very low 1.2V

Oh no! Free batteries appearing in the wild in Canada too!

Haven't seen either of those in the UK not even under a different brand name. [pileofstuff] measured 4V on the battery from the rechargeable , 3.3V on the non-rechargeable

Shortly before Poundworld closed down, they started selling more expensive items such as this Bluetooth keyboard.

I wonder if I can replace its puffy battery with one of the many I have now salvaged from discarded vape pens.

I bought this indoor drone for £4 at a charity shop but discovered that the battery charger was missing. I'll need to jury rig a charger for its 300mAh battery in order to test whether it still works. It still had a voltage of 3.75V but the props wouldn't start and the LEDs just blinked.

One of the 3 AAA batteries in the tilt sensing remote control was also leaking. The other two batteries have expiry dates of 2014 and 2019

A rare find outside the gates of a school - disposable vape device with a non-cylindrical battery. Of the 100+ single-use vape pens I've found discarded on the side of streets over the past year, the vast majority had rechargeable cylindrical batteries

Wonder who dropped it. Teacher, parent, or child

I'm afraid that I won't be able to salvage these lithium batteries I found in the street while walking back from town

Found another Lithium Lampyridea out in the wild -- that is, a rain soaked car park for some corner shops

Found the guts of another vapepen had already been removed.

Both look like they have been stepped on or driven over

And another 5 more batteries to add to my collection

Now approaching one year since I started collecting batteries littering the streets of England post-Lockdown

If I solder these in parallel and add a DC-DC boost converter will it be enough to power a Raspberry Pi? And for how long?

Very addicting this device habit of mine.

I cannot seem to stop myself taking apart single-use "disposable" vaping pens that I find discarded in the streets in order to salvage the components, namely the rechargeable batteries that they use, in most cases only once.

Tossed many non-viable ones into the battery recycling bins

And I still have a backlog of 24 more pens to disassemble!

Two rechargeable lithium polymer batteries, one from a disposable vape device and the other from a rechargeable e-cigarette with interchangeable atomizer and tank modules.

Can you guess which battery came from which device?

I have salvaged so many lithium batteries from the streets around me that I need to make specially designed storage solutions for them

I've salvaged so many unprotected Li-poly batteries from the street that I've run out of over-discharge protection PCBs. So I'm testing this rudimentary protection circuit which should shut off the TIP32a power transistor when the battery voltage drops below 3.2V = forward voltage of a white LED (2.6V) + base-emitter voltage drop (0.6V)
