At what point does one recycle 18650s?

I usually dispose of laptop pulls if they are under 1700mah capacity, measured in my hobby charger.

My hobby charger when discharging seems to indicate approx 10% less capacity with a new cell than than HKJ gets in his tests.

Interesting, i bought a Liitokala 300 which tests capacity, it just came the other day. I am surprised to hear yours reads lower then HKJs equipment, i assumed current measurement was more exact.

It only tests liIon to 3.0 volts. some batteries need to go below that to show maximum capacity. On the other hand most LEDs lose significant brightness well before 3.0 volts, so I’ve been happy just to measure useful capacity.

My Turnigy 8150 standard mode cutoff for lion @ 3.0V. Using NiMH discharge mode, changing load & cut off voltage for measuring capacity works on lion batteries to 2.8v. Max discharge rate on mine is 5A. But on another note I’m lazy and also use the default lion mode. My main use for the hobby charger is to charge & balance home built packs.
