This is some of the batteries i got last month from going around and asking politely from many locations and picking up some from locations that told me they would place them to the side for me...
The lithium batteries for your power wall i understand man. Good job on saving money on those.. But these old laptop batteries?
If you don't mind may i ask what you use them for? Thats a lot of junk that could be flammable if i understand correctly.
