The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. The same battery discharging at 0.5C should provide 500mA for two hours, and at 2C it delivers 2A for 30 minutes.Mar 9, 2017 C-rateTime Table 1: C-rate and service times when charging and discharging .. 더보기 How to choose the best power supply 1.
