li ion battery judge experience

Li-ion battery capacity could be divided into rated capacity and real capacity. Rated capacity means the minimum electric volume give out under standard discharge condition.


Li-ion battery is stipulated to charge the battery with 1C constant current to 4.2v constant voltage charge to small drain input, under standard temperature and humidity, and then discharge the battery with 1C, the real electric volume of which is battery's real capacity.


Also lithium battery real capacity restricted with discharge rate and temperature.

So lithium ion battery's capacity should specified clarified charging and discharging condition.


Capacity unit generally use mAh, 1Ah=1000mAh.
