All my 4.2V rechargeables are from laptop pulls: 4 Samsung “2.4Ah” and 6 “2.4Ah” Sanyo cells that I originally deemed ‘good’ from 3 laptop batteries. They accepted 2100-2300mAh charges a year ago and have seen regular use since. Their voltages stabilize at 4.14-4.17V after some sitting around. Under a 1A load, a fully charged cell’s voltage will immediately drop to 3.84-3.91V. Is that acceptable/expected/normal/safe?
