So it begins. The cells I had from generic laptop batteries - held about 1200mah, but got a little hot on discharge, so I have set them aside, for lower draw applications, torches and battery banks for mobile phones. I may revisit them for my big battery bank, just put a lower draw on them.
Then I dismantled one of my Lenovo batteries they hadSony SE US18650GR. 4 of which held more than 2000mah.
One Toshiba hadSanyo/Panasonic UR18650Y, which I am yet to test. These came from a working laptop battery, the laptop had a broken screen. Hoping that they are good, as apparently they only hold 1850mah new.
The second Toshiba had some Sanyo batteries that I cannot identify. They load test at 3.5v so they should be ok. Just chasing some data before I charge them
The marking on the side reads -
Sanyo R1112
003A
They have a purple top. I shall take some better pictures tonight.
For some reason I cannot upload the picture I have.
