DIY: How to revive a dead 18650 (or any) Li-ion battery cell

Check out my newest 18650 salvage video:
Today I will show you how to revive a dead 18650 Li-ion cell that’s being refused by the chargers. This method will work with any Li-ion battery, not just the 18650 cells. Here’s my follow-up video: if you wonder how much current (Amps) goes through the wire.
Note: this is not a permanent way to charge an 18650 cell. The point of this method is just to bring up the voltage of the dead cell to a point that is enough for a real 18650 charger to accept it and charge it properly. When a Li-ion battery does not have high enough voltage, the charger would not charge it. I think the reason is safety because if the voltage is too low, it might take a risk of charging a NiMH or NiCad cell which are only 1.2 volts each. And if you put a NiMH or NiCad cell (at 1.2 Volts) in a Li-ion charger that charges up to 4.2 volts, all hell will break loose.
Also: don’t overdischarge a Li-ion cells down to below 3V especially below the threshold recognized by the charger. Otherwise, it will not live long. The “Goldilocks” zone for a long and healthy Li-ion cell life is between 30% and 90% charge. Too much charge or discharge would be bad for the cell.

Dead Starbucks charger and devious thoughts.

The harsh life of a Starbucks USB charger. This one has clearly had one of its sockets mashed and an attempted repair that would be pointless unless it used swappable modules.
Note that it wasn’t really practical to explore this further due to it being in an airport after security, so tools would have been an issue. (And indeed someone with a big beard tampering with fitments.)
This did make me ponder if anything malicious could be incorporated into a charging socket like this. It would require that the phone’s charging port was capable of accepting something like a rubber ducky for a phone. (Pretends it’s a keyboard so it can run scripts without permission.) On further investigation it appears that some phones are vulnerable to that type of device.
The other very evil thing you could do is use a diode and resistor arrangement to charge a capacitor across the USB output to peak mains voltage or more to blow peoples phones up when they plugged them in to charge. Like a USB killer that works with any USB device.
It does make you wonder if the ideal charging lead for travel is perhaps one with the data pins isolated and a voltage protection device incorporated. Perhaps McDonalds has the right idea with their table mounted inductive charging coils.

1byone Car Jump Starter Review : How To Start Any Dead Car Battery in 30 Seconds:


So there you have it, a neat little gadget, which can easily jump start your car or charge any USB powered device on the go. The amazing thing is that if your car’s battery dies in the middle of nowhere, you don’t need to call your friend to help you out.

What is more, a great feature of this jump starter is that once you jump start your car, the vehicle’s battery fully recharges this power bank automatically in a matter of seconds. That’s why you don’t even need to bring any proprietary chargers.

In addition, this device has all kinds of security tricks like spark-proof technology and reverse polarity protection, so you won’t harm neither yourself nor the battery in any case.

Finally, the 1byone Car Jump Starter is an amazing piece of hardware and I don’t see any shortcomings. Well, the micro USB charging port would have been a nice addition, but hey, you are getting both a wall and car chargers, and sometimes you don’t even need to bother about charging the power bank up. All in all, for under $100 you are getting a multi-functional, lightweight and portable solution that, in my opinion, is worth every penny.

Resurrect Dead DeWalt Battery With a Old Battery Charger

Easiest way to check if you can resurrect a dead battery is to use tools that DeWald has provided. In this case i will be using a old DeWalt 18V battery charger with a tune-up button. This tune-up button sends short burst of current to the battery to wake up sleeping cells. This will work if your battery is not complacently dead.
