Hello Friends, You are welcome once again on this website, friends will talk in today’s blog post that what is the meaning of Ah-in battery, there is a lot of confusion about the question of whether we buy Batteries or Inverters. But sometimes we do not know what is the meaning of Ah on the battery we have bought, let us know about this today, you must read this post till the end?
What is Ah in Battery? What is Ah in Battery?
So the Ah in Batteries tells the capacity of the battery like whether a battery is 50 Ah or is 100 Ah or is there a battery of 150 Ah? So Ah means ‘A’ to Ampere and ‘H’ to hour i.e. Ampere-Hour?
As if there is a battery of 100 Ah so it means that this battery will give 100 Ampere current in output for one hour yes?
Now if I am running a load from this 100 Ah battery which consumes 100 Ampere current, then this 100 Ampere load can last for 1 hour, what is the capacity of this battery?
Now, friends, many people make a mistake here, the very thing to note here is that the 100 Ah battery which is giving 100 Ampere current in 1 hour is for an empty DC circuit, yes? Because the battery outputs DC current, that’s why?
Now, most of the people here understand that if a battery is 100 Ah then it means that that battery can run 100 Ampere AC load for 1 hour but friends this is absolutely wrong, a 100 Ah battery empty 100 Ampere Can run DC load for 1 hour, yes? Because the battery gives DC supply in the output, that’s why?
Now if you people are having confusion, then we see it through a normal C calculation?
Now let’s total all the devices we are running here?
Fan = 65 * 2 = 130 Watts
Bulb = 10 * 1 = 10 Watts
T.V. = 100 * 1 = 100 Watts
Total House load = ( 130+10+100 ) = 240 watts
Now here the total load of the house has come to ‘240 watts’ Now here we calculate the current for both AC and DC because the devices in the houses we use mostly run on AC supply, let’s see the calculation?
AC Current Required for 240 Watts load
Power = Voltage * Current * Power Factor
Power = V * I * Power Factor
240 = 220 * I * 0.8
I = 240 / 220 * 0.8
I = 1.36 Ampere
DC Current Required for 240 Watts load
Power = Voltage * Current
Power = V * I
240 = 12 * I
I = 240 / 12
I = 20 Ampere
Now here you have seen that the current calculation of 240 watts is coming in different for the load we are running, in AC the current 1.36 Ampere is coming on the same load while the current 20 Ampere is coming in DC on the same load. ?
What do we understand by this? From this we understood that what we talked about was that the 100 Ah battery had the capacity to deliver 100 Ampere Current in 1 hour but the load should be of DC, that’s why it was called 100 Ah?
Now here we have calculated on both the loads, in which the calculation came in DC, 20 Ampere DC current on the load of 240 watts, this is the same DC current, on the basis of which the Ah of any battery is calculated?
Now here we see that if we run this 240 watts AC load from a 100 Ah battery, then how many hours can that battery backup?
So we had 240 watts of DC current at 20 Ampere
So the battery is 100 Ah?
So, Time in Hours = Battery Ah / DC load Current
Time in Hours = 100 Ah / 20 Ampere
Time in Hours = 5 hours Approx.
So friends, here we understand from this calculation that if an AC load is 240 watts, then it can run for 5 hours with a 100 Ah battery?
Friends, this is the real way to calculate any load or to remove any battery backup time?
So friends, this actually means Ah-in any battery?
