Qui est le meilleur fabricant de batteries mobiles?

Panasonic est le leader de la batterie au lithium. LG Sony et Samsung ont également de grands départements de recherche.. Mais en retard sur Panasonic en capacité et il est également utilisé par tesla dans leurs voitures. Juste à titre d'exemple le 18650 qui est de 1860mah qui était la capacité d'origine de la batterie Li Ion utilisée presque partout, ils ont 4400 mah in the same shape and size now. While most Chinese are under 1000mah..

Although not necessarily, I have over 20 year old Li ion batteries still in working condition made by LG Sony etc.. But these were only charged to under 4.10 volts.. None of the batteries charged above that voltage to get higher capacity lasts even 5 years and usually go bad in 1 or 2 ans. if 4.1v is 100% 4.2 gives like 120% and 4.4v gives over 30% etc.. But the faster the battery will die over the 4.1 volts.. Capacity also drops faster for each recharge.. IE a battery charged to 4.3 volts will drop double the capacity each recharge than a battery that is only charged to 4.2 volts. So except capacity to drop much faster for batteries charged higher.

So as you can capacity is directly related to voltage and also directly related to capacity drop. I dont have any Panasonic batteries still working because they sell on capacity and hence charged to higher voltage but they dont expect you to use the device more than a couple of years max anyway.

I do not like our disposable culture. That is a lot of waste. Waste that is dangerous. And no one disposes the waste properly.
