Each battery as it leaves the manufacturer''s premises has a capacity rating indicated ...
C-rates determine the charge and discharge rates of a battery. The battery''s capacity is commonly rated at 1C, indicating that a fully charged battery rated at 1Ah should provide 1A of current for one hour. Discharging at 0.5C would provide 500mA of current for two hours, and at 2C, it would deliver 2A of current for 30 minutes.
Here is an example of the capacity of two batteries. A cell phone on average has 10 watt hours battery capacity. If we let a lego block represent one watt hour it looks like this. A Currentium Power Bank has a true measured output …
