Optimized charge, battery health management ad AlDente App.....

Thanks for your opinion. I also think more or less the same thing, and coming from the world of solar or stationary lead acid batteries, I know for example that the manufacturers of these batteries have recommended very few things for 30 years to guarantee maximum performance (3 step charge, keep the 100% as much as possible, equalization in some case and temperature compensation etc ..).

While the sellers of chargers and accessories always offer a bunch of techniques (7-step, 9-step charge, pulse charge) that battery manufacturers and scientific research HAVE NEVER recognized. Often these extravagant and complicated features even result in the loss of the battery manufacturer's warranty.

I think something similar happens in the world of third-party apps and Li-ion batteries.

I am not a computer technician or software engineer but I think making an app like aldente and the like is quite simple. And if Apple (or android) has not provided for a manual charge limit by the user, it is not due to inability, but a deliberate choice.

It is enormously more complicated to design an automatic management system than a simple App that disconnects the charger at some point.

But in many forums it is now law to say that leaving the Mac at 100% connected to the Net causes rapid destruction of the battery.

Even now it is said that those who always use a macbook as a desktop should leave the battery at 50%.

I also think that what degrades the battery is not 100% itself, but rather the continuous charging from 80 to 100%, which is the part where the most temperature is generated.

But if this doesn't happen all the time, the operating system lets it calmly reach 100%.

Which is actually a slightly lower real percentage.

Thank you, yes I now the article.

Li-ion battery have the best density energy on the market. Bat lifepo4 have more cycles durability and some type of lead acid even more. For example big stationary Opzs tubular plate flooded lead acid battery. Theyr life can be to 15/20 years of standby use or 4000/6000 cycle. But they energy density is poor and you can discharge regularly only to 30% DOD to last maximum life. And they need a precise maintenance regularly. Refill lost water and periodically equalize charge to combat electrolyte stratification on the floor of the battery. But they can life without problem 12/15years and maybe 20 years,before their capacity drop less 70\80% of nominal capacity.

Li ion and lifepo4 can be discharged regularly with 80/90% DOD.

But li ion have no exceptional cicle life, I think from 600 to 1200 cycles.

Li ion and even more lifepo4 can be charged and discharged with hy current rate (1C). Lead acid have a seafty limit of 0.1/0.2C in charge(the charge is extremely slow, 24 hours from 0 to 100%).

And discharging with high C rate cause the drop of real capacity.

These is peukert coefficient.

Lithium battery have more better peukert coefficient and they conserve almost 100% of nominal capacity also with high C rate (high discharge current).

These is because have very low internal resistance.

Personally I don't now why lithium battery don't love 100% SOC.

Instead, I now why lead acid battery extremely love 100% SOC and in some case regularly controlled overcharge.
