Know the battery capacity 450mah and power 22W, find the time t?


First of all, I'll explain to you that the battery capacity of 450mahm means "millisecond"; a means "ampere"; H means "hour"; capacity of 450mah means: with 450mah as the discharge current, it can discharge for 1 hour. Because 1A = 1000mA, 1 hour = 3600 seconds = 3600s, so 450mah = 0.45a × 3600s = 1620 (a



Battery capacity and power, 1W = how much capacity? Or how to understand? Which is bigger?


The capacity of a battery is ampere hour (or milliampere hour), that is, how many hours it can discharge with a certain current. By Watt, you mean how much power the battery can discharge with, that is, the battery voltage multiplied by the discharge current. Voltage * working current = power; 1 watt = 1 ampere * 1 volt; discharge = ampere * hour. The battery voltage is fixed, so the larger the wattage, the greater the capacity

Is the unit of battery capacity MAH the unit of electric energy? What is mah?
How to convert it to kW. H?
If it's not electric energy unit, it can't be converted. What unit is it?
Why does the battery capacity unit use it?


For example, a 1.2V 2000mAh battery means that the battery can continue to discharge at 2000mA for 1 hour, or at 1000mA for 2 hours, and so on. Due to different battery voltages, the value of MAH can not compare the electric energy of different batteries
