Hello.I just salvaged 12 cells from old laptop batteries, but I have small issue with them. Six of then had 3.88V another had 4.08V, I get them charge thru one of that cheap 18650 charger to the 4.2V each, till that everything looks great but when I try found out their cappacity by discharging with LiPo charger at 1A I get only 480mah and at 0.5A 1200mah and Volts imidiatly falls from 4.2V to around 3.9V. I have pink one Sanyo cells, they should have 2600mah from 2010.Can they lost so much capacity over the time??? Or I am doing something wrong??
