A lot of readers are asking: Where do I get dead batteries?:
I mostly got these batteries by seeing and asking for them. New cars wreck batteries pretty quick because the car computer never really turns off. So if the car isn't driven regularly it'll over-discharge and sulfate the battery.
I tell my friends to give me their toxic waste and I'll get rid of it, cuz I hate seeing buckets of drain oil left out in the rain. They give me their dead batteries also.
I picked up a few behind service stations and parts stores where people had orphaned them. A few came from my marina next to the dumpster, more came from the marine supply store. I told them I was experimenting with desulfating batteries and they told me to help myself to their scrap pile. Some came back to life from various magic treatments and I gave them to friends or built them into projects.
Those projects included as welders and power storage for solar welders, running power tools off them, as well as starting and lighting batteries for the Free Yacht.
I finally got around to taking the bad ones to the scrapyard and damn!
Here's what the robo-cashier at the scrapyard gave me for my load of toxic waste!
Batteries are worth real money now, if you can find the right buyer.
Step 1: Check the Market
Check the values online or in your paper, if it has a commodity markets listing.
You'll get less than this, because you're not selling a train car full. Unlike retail economics, in collection economics smaller quantities are worth less per pound.
If you're in a city with a port that ships to China, expect to get a higher price than elsewhere.
If you have a huge quantity, bargain up for a higher price. The yards that load ships won't usually bother with you unless you've got truckloads, but if you do, they'll pay accordingly higher.
"TL" means "Truck Load". "LTL" means "Less than Truckload".
