I've recently bought a box of 160 new QB18650 12A cells and will only use 144 for my build. So I'm trying to quickly weed out the worst ones. I don't have an accurate way to test quickly so am wondering if there are any other properties that could identify the weaker cells.
90% of them are above 46.0g, but some weigh less (such as 45.89g), would these cells be weaker given they have less of something? Otherwise, I could measure voltage to detect self discharge? All measure close to 3.50V as shipped.
