Amp Hour Battery Explained. In simple terms, it’s used to define the amount of current a battery can supply in an hour. As clear from the name “ampere hour” is the amount of current that flows for an hour.
Theoretically, we can draw 5 amps, continuously, for 60 minutes before our 5 amp hour battery is drained. Under ideal conditions, a cordless lawn mower that continuously draws 2.0 amperes (amps) of current will drain the total charge of a 2.0ah battery in 1 hour. We use this to help understand how long our battery will power our appliances before it is going to need to be charged.
A typical amp hour specification might read, “100 ah @ 20hr”. Amp hour is the rating used to tell consumers how much amperage a battery can provide for exactly one hour. It's used to estimate the amount of energy a battery can hold.
This is an important distinction to make because. The power and longevity of a battery is noted by its amp hour (ah) rating. The ah rating is the thing that decides to what extent your battery will last per charge.
Take whatever you want your load to be and multiply it by the number of hours you want to run it. A 5c rate for this battery would be 500 amps, and a c/2 rate would be 50 amps. So the c of a 2ah battery is 2a.the amount of current a battery 'likes' to have drawn from it is measured in c.the higher the c the more current you can draw from the battery without exhausting it prematurely.
If playback doesn't begin shortly, try restarting your device. Now, that’s under ideal conditions, perfect temperature, no vibration, and consistent power. The specification is saying that the battery will provide 5 amps of current at a useable voltage, continuously for 20.
This is often referred to as the ‘capacity‘ of a battery. As clear from the name “ampere hour” is the amount of current that flows for an hour. In simple terms, it’s used to define the amount of current a battery can supply in an hour.
