Over my 8 years of buying and selling laptops I have accumulated over 200 pounds of dead laptop batteries. Before getting into this battery stuff I always wanted to just get rid of them but held onto them since my conscience always told me to follow the garbage companies rules and not throw them in the garbage luckily(I hope) I now have a bunch of useful power storage. I have opened half of them and found that most even if they are 0v can be brought back to life by reviving them with good cells in parallel. They are basically useless for high drain applications, I made a 20ah pack of them and it would only run my scooter at half speed and get too hot even running at 1c. Anyways I wanted to build a few solar panels and a fire proof container for the cells for a summer project. Is there anything I can do with them? Was thinking some kind of low amp draw like maybe heating my water? Maybe some lighting??
Uses for 200+ lbs of old laptop cells?

If you search ebay, you can find affordable flashlights that use one or two of the 18650 cells. Search 18650 LED flashlight.
The used cells can be separated into two piles, "too far gone to use for anything", and "still has some life in them". The flashlights can be gifts, or used as headlights for your E-bikes? I specifically got the two-cell charger that operates off of 12V from a car, and I use an adapter to charge from the wall socket in my home.

Latecurtis on this forum is looking for a new battery, and is unemployed and disabled and desperately seeking a better battery. If you two are in the same country, would you consider giving him some to build a new battery? With a 450W, 24v controller, he's drawing less than 20A, so not a high drain device.

I'd offer to help, but I suspect he's in the US, since he talks about Medicaid.

Depending on your location, gifting some more or less ok cells to a hard pressed ES member is not a bad idea.
But, they'd have to have a minimum skill level to use them, unless you are willing to actually build a pack for the person.

As my rule I put cells at zero volts in the recycle bin for safety reasons. I don't know the cut off point maybe 2.8 volt or higher. The other test is volume, capacity. A shitty cell in line with a good cell is no help to you. These is for a faster easier build. As lower risk of fire. Good luck.

that guy wanted SLA batteries, not lipo cans.
too bad nobody ever learned where he lived or maybe someone coulda helped.
i already gave some SLA to another guy who was on relief and even worked on his controller to make his 48V scooter run but he went all mental on me because he decided i was working too fast repairing the phase wires that had been improperly connected with the little clips that clamp on the wire and stick a little prick pin through the insulation like is used to add something to the wiring in your car without a real connection. while i was working on it he decided i had to stop because he could not keep up with what i was doing. he was mental.

The pack I had used in my scooter was 7s and I pulled it apart after it failed. Running the scooter in slow mode (econo) drains 12-15amps and even then it was slow and accelerated poorly. They are really in no shape to use as any kind of electric vehicle.

? boat anchor and 'fishing' tool (if you electrocute them they'll float up and are easy to catch)

Then they just need to be recycled. How that is done where you live I have no clue. In my town, I can take batteries to the city dump transfer station, where they accept batteries, oil, paint, etc.
Find out what they do in your town. Before we had the full recycling setup in my town, they still had a day twice a year you could bring your dangerous shit to get rid of it.

200 pounds of dead laptop batteries? I hope it's in a brick shed with good access for the fire department.
Will these sort of things ever be worth anything in scrap?
I just wouldn't build from used cells. At 8 years old I wouldn't want anybody too. My lipo kit has a 3 year shelf life. I dunno what you have, but 8 years seems excessive.
I see you built a 20Ah pack and it unsurprisingly didn't work. 20Ah@36v is $250 brand new, but it would work. Spending less might just leave you with nothing. Bad value.
