Wer ist der beste Hersteller von Mobilbatterien??

Panasonic ist der führende Anbieter von Lithiumbatterien. Auch LG Sony und Samsung haben große Forschungsabteilungen.. Aber hinken Panasonic in der Kapazität hinterher und werden auch von Tesla in ihren Autos verwendet. Nur als Beispiel die 18650 Das sind 1860 mAh, was der Li-Ion-Akku mit ursprünglicher Kapazität war, der fast überall verwendet wurde, Sie haben 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 Jahre. 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.
