Greetings:
There have been several threads of late about the some of the newer designed LiCo 18650 cells that specify a 4.35V maximum charge voltage before switching to CV. Some have hypothesized that these cells will last longer if charged on a traditional charger that uses a 4.20V maximum charge.
While this may be true, it is possible that the danger window before something bad happens has just been shrunk (as a sliding scale ( risk)) from 4.2--4.5 to 4.35--4.5V. To use an example, the pharmaceutical industry regards one of the safety factors in new drugs to be the difference between a therapeutic dose of medication and the LD50 (lethal dose). The narrower the gap the riskier the medication is (obviously this is just one factor).
Does anyone with more experience than I have formal insight into how the changes to these new generation of 4.35V LiIons effects longevity and/or safety?
