Hi Hank.
You need to be a bit more specific.
Are you after a few laptop packs to break apart, or already tested cells or new cells? Quantity? Few or thousands?
I'm UK based, Northumberland and my experience of obtaining good cells in UK is not good.
All the laptop packs on E-bay or overpriced and poor quality.
I resorted to buying modem packs from Battery Hookup and for that's a far better option for me to obtain as new cells that all test great.
cheers

Hi Steve,
I am looking for recycling centre, scrap yard, or place where I can buy scrap laptop, bike batteries per kg.
I would like to build 10kWh battery storage system for my home usage. So I believe I need about 500-1000 scrap laptop batteries.
To be honest I have started breaking apart some laptop batteries, I have about 150 cells left to test. Results are really bad. I believe I have few options. First one is to buy some old laptop scrap batteries and continue breaking. Second is to buy two Tesla modules and brake them apart. Or third option is to buy brand new cels form Battery Hookup (mentioned by you), but the shipping cost is two times more than cost of the cells. Is it normal that delivery is so expensive?
So far I have asked all bike shops, mobility shops around me, and they refused to sell or give any scrap batteries. I will try local recycling centre next week (I was told they should be open from next week). Can I ask you what type of inverter/charger you have? I have PV solar panels fitted by Ashadegreener company , 9 years ago and I can only use AC coupled battery system. Is Sofar ME3000SP a good choice for me or can you recommend better device?
Regards,
Hank,
